    Adafruit Inductive Charging Set - 5v @ 500ma Max [ada1407]

    -Titulo Original : Adafruit Inductive Charging Set - 5V @ 500mA max [ADA1407]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1407 // Stock Type: Power >> Inductive Chargers // In Stock & Ready to Ship // The squarish board with two chips on it is the transmitter (power with 9V).  The longer board is the output and you can connect that to the part of your project that needs powering.Inductive charging is a way of powering a device without a direct wire connection. Most people have seen inductive charging in a rechargable electric toothbrush: you may have noticed that you recharge it by placing it into the holder, but there's no direct plug. These chargers work by taking a power transformer and splitting it in half, an AC waveform is generated into one, and couples into the second coil. This is a basic charger set, and it does work, providing 5V DC output from the output half when the input half is powered with 9V to 12VDC. You can draw as much as ~500mA if the coils are 2 or 3 mm apart. If you only need 100 or 200mA you can be up 7mm apart. For 10mA draw, the coils can be up to half an inch (12.5mm) apart. Any non-ferrous/non-conductive material (eg air, wood, leather, plastic, paper, glass) can be used between the two coils. The material doesn't affect the distance or efficiency. The coils do need to be fairly co-axial, try to get them to be parallel and have the circles line up for best power-transfer. (This is why the electric toothbrush must fit into the plastic holder, it's lining up the two coils for best efficiency) Because its an air-core transformer, it's fairly inefficient. Only about 40% of the energy in shows up on the other end, but for low power or charging project. If you draw 5V 100mA on the output side (0.5W), you'll need 0.5W * 2.5 / 9V = ~150mA from the input end. The quiescent current is about 70mA at all time, even when the other coil is not anywhere near by. These are basic modules, probably used for some low cost toy. We don't have any datasheets or specifications for them. We do see a feedback resistor divider on the output side using 0...

    Adafruit 3297 DRV8833 DC/Stepper Motor Driver Breakout Board

    -Titulo Original : Adafruit (PID 3297 DRV8833 DC/Stepper Motor Driver Breakout Board-Fabricante : Adafruit-Descripcion Original: DRV8833 motor driver chip // Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel // 2 full H-bridges // 2.7V to 10.8V motor power // DRV8833 an handle a peak of 2A, but only for a short amount of time // Spin two DC motors or step one bi-polar or uni-polar stepper with up to 1.2A per channel using the DRV8833. This motor driver chip is a nice alternative to the TB6612 driver. Like that chip, you get 2 full H-bridges, but this chip is better for low voltage uses (can run from 2.7V up to 10.8V motor power) and has built in current limiting capability. We set it up for 1A current limiting so you don't get more than 2A per chip, but you can also disable the current limiting, or change it to a different limit! We solder on DRV8833 onto a breakout board for you here, with a polarity protection FET on the motor voltage input. Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive two DC motors bi-directionally, or one stepper motor. Just make sure they're good for about 1.2 Amp or less of current, since that's the limit of this chip. They do handle a peak of 2A but that's just for a short amount of time, if you turn off the current limiting we set. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver! You also don't have to worry as much about burning out the chip with overdriving since there is current limiting. There's two digital inputs per H-bridge (one for each half of the bridge), you can PWM one of the inputs to control motor speed. Runs at 2.7V-10.8V logic/motor power. The motor voltage is the same as the logic voltage, but logic voltage from 2.7V or greater will work so no need to worry if you are powering the motors from 9V and using 3.3V logic. For higher voltages, check out the TB6612. For much higher voltages and currents check out the DRV8871! Comes as one assembled and tested breakout plus a small strip of header. You'll need to do some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power supply not included...

    Adafruit Rotary Encoder (1 piece)

    -Titulo Original : Adafruit Accessories Rotary Encoder (1 piece)-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 377 // Stock Type: Sensors >> Touch // In Stock & Ready to Ship // This rotary encoder is the best of the best, its a high quality 24-pulse encoder, with detents and a nice feel. It is panel mountable for placement in a box, or you can plug it into a breadboard (just cut/bend the two mechanical side tabs.) We also include a nice soft-touch knob with an arrow in it, fits perfectly and looks great. This encoder also has a push-button built into it so you can press onto the knob to close a separate switch. One side has a 3 pin connector (ground and two coding pins) and the other side has two pins for a normally-open switch.Rotary encoders are useful as rotation sensors or selectors and look similar to potentiometers. However they are not like potentiometers at all, so it's important to realize the difference! These rotary encoders rotate all the way around continuously, and are divided up into 24 'segments'. Each segment has a click-y feeling to it, and each movement clockwise or counter-clockwise causes the two switches to open and close. There is no way to know what the current 'position' is - instead you would use a microcontroller to count how many 'clicks' left or right it has been turned. If you need to detect rotational 'position' a potentiometer would be a better choice...

    Adafruit Dotstar Digital Led Strip - Black 144 Led/m - 0.5.

    -Titulo Original : Adafruit DotStar Digital LED Strip - Black 144 LED/m - 0.5 Meter - BLACK [ADA2328]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 2328 // Stock Type: LEDs >> Strips // In Stock & Ready to Ship // Move over NeoPixels, there's a new LED strip in town! These fancy new DotStar LED strips are a great upgrade for people who have loved and used NeoPixel strips for a few years but want something even better. DotStar LEDs use generic 2-wire SPI, so you can push data much faster than with the NeoPixel 800 KHz protocol and there's no specific timing required. They also have much higher PWM refresh rates, so  you can do Persistence-of-Vision (POV) and have less flickering, particularly at low brightness levels.Like NeoPixels, DotStar LEDs are 5050-sized LEDs with an embedded microcontroller  inside the LED . You can set the color/brightness of each LED to 24-bit color (8 bits each red green and blue). Each LED acts like a shift register, reading incoming color data on the input pins, and then shifting the previous color data out on the output pin. By sending a long string of data, you can control an infinite number of LEDs, just tack on more or cut off unwanted LEDs at the end. The PWM is built into each LED-chip so once you set the color you can stop talking to the strip and it will continue to PWM all the LEDs for youHowever, unlike NeoPixels, these LEDs have 2 wires (input and output) for sending data - one clock pin and one data pin. That means you need two pins, not one, to control DotStars.  Because the clock and data is seperated, you can use any processor speed or type to control these strips, and you don't have to worry about being careful with the timing . Hardware SPI support is handy but not required. This makes them excellent for use with any microcontroller or microprocessor, including Arduino, Raspberry Pi, BeagleBone, Propeller, SparkCore, and any 'raw' microcontrollers/microprocessors. It's very easy to port the library, and you can send data to the pixels at up to 32MHz clock rate!Another nice thing about DotStars is their high PWM rate. You only have to set the 24-bi...

    -Titulo Original : Adafruit 4279 Ultimate GPS With USB - 66 Channel W/10 Hz Updates-Fabricante : Adafruit-Descripcion Original: The Bluefruit can also act like an HID Keyboard (for devices that support BLE HID) // Can become a BLE Heart Rate Monitor (a standard profile for BLE) - you just need to add the pulse-detection circuitry // Turn it into a UriBeacon, the Google standard for Bluetooth LE beacons. Just power it and the 'Friend will bleep out a URL to any nearby devices with the UriBeacon app installed. // Built in over-the-air bootloading capability so we can keep you updated with the hottest new firmware. Use any Android or iOS device to get updates and install them! // Add powerful and easy-to-use Bluetooth Low Energy to your robot, art or other electronics project! With BLE now included in modern smart phones and tablets, its fun to add wireless connectivity. So what you really need is the new Adafruit Bluefruit LE SPI Friend! The Bluefruit LE SPI Friend makes it easy to add Bluetooth Low Energy connectivity to anything with 4 or 5 GPIO pins. With SPI, you don't have to worry about baud rates, flow control, or giving up a hardware UART port. Connect to your Arduino or other microcontroller using the common four-pin SPI interface (MISO, MOSI, SCK and CS) plus a 5th GPIO pin for interrupts (to let the Arduino know when data or a response is ready). This multi-function module can do quite a lot! For most people, they'll be very happy to use the standard Nordic UART RX/TX connection profile. In this profile, the Bluefruit acts as a data pipe, that can 'transparently' transmit back and forth from your iOS or Android device. You can use Adafruit's iOS App or Android App, or write your own to communicate with the UART service. If you like Serial communication more than SPI, we also have a version that can talk UART The board is capable of much more than just sending strings over the air! Thanks to an easy to learn AT command set, you have full control over how the device behaves, including the ability to define and manipulate your own GATT Services and Characteristics, or change the way that the device advertises itself for other Bluetooth Low Energy devices to see. You can also use the AT commands to query the die temperature, check the battery voltage, and more, check the connection RSSI or MAC address, and tons more. Really, way too long to list here...

Resistive touch screens are incredibly popular as overlays to TFT and LCD displays. If you want to connect one to a computer you need something to handle the analog to digital conversion. Most converters we've found are not very easy to use, and are 'fixed' - making them difficult to calibrate. The AR1100 is a nice chip that solves this problem by acting as a touch->USB converter and also comes with calibration software. The calibration software is Windows only, but once you've calibrated you can use the screen on any OS. The AR1100 shows up as a regular Mouse or Digitizer HID device so no drivers are required. We've tested it sucessfully on Mac, Windows, and Debian Linux (Raspbian on a Raspberry Pi). Other Linux distributions may or may not work, but if you're running Linux you're probably used to that.This breakout board features the AR1100, which has both USB and UART interfaces available. 99% of the time, you'll want to use the USB interface but there is some functionality for getting TTL UART data out (see the datasheet for details) There is also a red LED that lights up to indicate when a touch has been detected. For the screens that have 1mm pitch FPC cables, you can plug the cable right into the connector. The majority of medium/large touchscreens have that kind of connector. If you have another kind of touch screen, the four X/Y contacts are available on 0.1 pitch breakouts so you can hand-solder or wire them. We set this breakout up for 4-wire sensing only. You can pretty much just plug and play to get started, for more details including calibration software, check out the AR1100 page . Plug any 1mm-pitch 4-wire resistive touchscreen to the on-board FPC connector, when you plug into a computer's USB port you should see a new device and touching the screen will cause the mouse cursor to move around...

    Adafruit Stereo 2.1W Class D Audio Amplifier - TPA2012

    -Titulo Original : Adafruit Stereo 2.1W Class D Audio Amplifier - TPA2012-Fabricante : ADAFRUIT-Descripcion Original: Output Power: 2.1W at 4Ω, 10% THD, 1.4W at 8Ω, 10% THD, with 5V Supply // PSRR: 77 dB typ @ 217 Hz with 6 dB gain // Designed for use without an output filter, when wires are kept at under 2"-4" long // Four pin-selectable gains: 6dB, 12dB, 18dB and 24dB. Select with the onboard switches or by setting the G0 and G1 breakout pins // Thermal shutdown protection // This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 2.1W channels into 4 ohm impedance speakers (@ 10 pct THD). Inside the miniature chip is a class D controller, able to run from 2.7V-5.5VDC. Since the amp is a class D, it's incredibly efficient (89 pct efficient when driving an 8 ohm speaker at 1.5 Watt) - making it perfect for portable and battery-powered projects. It has built in thermal and over-current protection but we could barely tell it got hot. This board is a welcome upgrade to basic LM386 amps. The inputs of the amplifier go through 1.0uF capacitors, so they are fully 'differential' - if you don't have differential outputs, simply tie the R- and L- to ground. The outputs are Bridge Tied - that means they connect directly to the outputs, no connection to ground. The output is a ~300KHz square wave PWM that is then 'averaged out' by the speaker coil - the high frequencies are not heard. All the above means that you can't connect the output into another amplifier, it should drive the speakers directly. Comes with a fully assembled and tested breakout board with 1.0uF input capacitors. We also include a dual mini DIP switch for setting the amplifier gain on the fly, 3.5mm screw-terminal blocks so you can easily attach/detach your speakers, and some header in case you want to plug it into a breadboard.

    Adafruit TCA9548A I2C Multiplexer [ADA2717]

    -Titulo Original : Adafruit TCA9548A I2C Multiplexer [ADA2717]-Fabricante : ADAFRUIT-Descripcion Original: Finally, a way to get up to 8 same-address I2C devices hooked up to one microcontroller - this multiplexer acts as a gatekeeper, shuttling the commands to the selected set of I2C pins with your command. // Using it is fairly straight-forward: the multiplexer itself is on I2C address 0x70 (but can be adjusted from 0x70 to 0x77) and you simply write a single byte with the desired multiplexed output number to that port, and bam - any future I2C packets will get sent to that port. In theory, you could have 8 of these multiplexers on each of 0x70-0x77 addresses in order to control 64 of the same-I2C-addressed-part. // Like all Adafruit breakouts, we put this nice chip on a breakout for you so you can use it on a breadboard with capacitors, and pullups and pulldowns to make usage a snap. Some header is required and once soldered in you can plug it into a solderless-breadboard. The chip itself is 3V and 5V compliant so you can use it with any logic level. // You just found the perfect I2C sensor, and you want to wire up two or three or more of them to your Arduino when you realize Uh oh, this chip has a fixed I2C address, and from what I know about I2C, you cannot have two devices with the same address on the same SDA/SCL pins! Are you out of luck? You would be, if you didn't have this ultra-cool TCA9548A 1-to-8 I2C multiplexer!

    Adafruit 3296 DS1307 Real Time Clock Breakout Board

    -Titulo Original : Adafruit 3296 DS1307 Real Time Clock Breakout Board-Fabricante : Adafruit-Descripcion Original: DS1307 Real Time Clock Breakout Board This real time clock (RTC) with battery backup allows your microcontroller project to keep track of time even if it's reprogrammed or if the power is lost. It's perfect for data logging, clock-building, time stamping, timers, alarms, and more. The DS1307 is the most popular RTC but it requires 5V power to work (although we've used it with 5V power and 3.3V logic successfully). The DS1307 is simple and inexpensive but not a high precision device. It may lose or gain up to 2 seconds a day. For a high-precision, temperature compensated alternative, take a look at the DS3231 precision RTC . It works great with an Arduino using our RTC library or with a Raspberry Pi (or similar single board linux computer) . Note: This product does not come with a CR1220 coin cell battery. We recommend you purchase a CR1220 coin cell battery to use with this product. Features PCB & header are included Plugs into any breadboard, or you can use wires Two mounting holes Will keep time for 5 years or more Specifications Length: 25.8mm/1.02in Width: 21.7mm/0.85in Height: 5mm/0.2in Weight: 2.3g/0.09oz Mounting holes are 2.2mm(0.086in) diameter, 25mm(0.98in) apart This board/chip uses I²C 7-bit address 0x68 .

    Adafruit 1335 Peltier Thermoelectric Cooler Module With Heat

    -Titulo Original : Adafruit 1335 Peltier Thermoelectric Cooler Module With Heat Sink Assembly, 12 Volt, 5 Amp-Fabricante : Adafruit-Descripcion Original: Keep the heat down with a peltier module. These unique electronic coolers can generate a temperature differential when powered. Put simply, apply 12V 5a power supply to the red (positive) and black (negative) wires and one side will get frosty cold while the other side gets hot. For best results, you'll need to wick away that heat (otherwise the cold side will slowly get warmer). a fan and/or heat sink is ideal. The unit comes fully assembled with the peltier module, heat sink and fan. This is a 12V module, and is rated for up to 72 Watts max (up to 14V/6a) but when used with a regulated 12V output, they don't draw much more than 5 Amps, so we suggest our 12V/5a power adapter for use. (You will need to cut the connector and expose the wires or use a power jack to screw terminal adapter.). Max current: 6a at 12V. Suggested voltage range: 12V to 15.5V. Maximum temperature differential (tmax at QC = 0): 66°c. Maximum cooling power (QC max.) at 15.3V: 97W. 127 peltier elements. DC resistance: 2.5 ohms. Silicone seal. Peltier module: 1.6 inch x 1.6 inch x 0.13 inch (40 x 40 x 3.5 mm). aluminum plate: 1.6 inch x 2.4 inch (40 x 60 mm). heat sink: 3.5 inch x 3.5 inch (90 x 90 mm)...

    Adafruit Pro Trinket 5v 16mhz (1 Unidad)

    -Titulo Original : Adafruit Pro Trinket 5V 16MHz (1 Piece)-Fabricante : Adafruit -Descripcion Original: Chip integrado ATmega328P en paquete QFN Velocidad de reloj de 16MHz, FLASH de 28K disponible El cargador de arranque USB con un buen indicador LED se parece a un USBtinyISP para que pueda programarlo con AVRdude y / o Arduino IDE (con algunas modificaciones simples de configuración). También tiene encabezados para un puerto FTDI para reprogramación Conector micro-USB para alimentación y / o carga USB, puede colocarlo en una caja o pegarlo con cinta adhesiva y usar cualquier cable USB para cuando desee reprogramar. Regulador de potencia incorporado de 5.0V con capacidad de salida de 150mA y caída ultra baja. Entrada de hasta 16 V, protección de polaridad inversa, protección térmica y de límite de corriente. Trinket tiene una hermana mayor en la ciudad: ¡Pro Trinket 5V! Pro Trinket combina todo lo que te gusta de Trinket con la familiaridad del chip Arduino de núcleo común, el ATmega328. Es como un Arduino Pro Mini con más pines y USB, tan delicioso. Trinket ya tiene un año, y aunque ha sido genial ver toneladas de pequeños proyectos, a veces solo necesitas más pines, más FLASH y más RAM. Es por eso que diseñamos Pro Trinket, con 18 GPIO, 2 entradas analógicas adicionales, 28K de flash y 2K de RAM. Al igual que el Trinket, tiene soporte de carga de arranque USB integrado: esta vez optamos por un conector MicroUSB. También agregamos el soporte Optiboot, para que pueda programar su Pro Trinket a través de USB o con un cable FTDI al igual que el Pro Mini y sus amigos. El Pro Trinket PCB mide solo 1.5 x 0.7 x 0.2 (sin encabezados) pero tiene casi la misma capacidad que un Arduino UNO. Por lo tanto, es excelente una vez que haya terminado un prototipo en un Arduino UNO oficial y quiera hacer el proyecto es más pequeño. El Pro Trinket 5V usa el chip Atmega328P, que es el mismo chip central en el Arduino UNO / Duemilanove / Mini / etc. a la misma velocidad y voltaje. Por lo tanto, le alegrará saber que no solo es Pro Trinket programable usando el IDE de Arduino como ya configuró, ¡pero el 99% de los proyectos de Arduino funcionarán de inmediato! Aquí hay algunas cosas que debe tener en cuenta al adaptar los bocetos de Arduino: los pines # 2 y # 7 no están disponibles (están exclusivamente para USB) El regulador de 5 V integrado puede proporcionar una salida de 150 mA, no una salida de 800 mA. No puede enchufar los protectores directamente en Pro Trinket. No hay un chip de serie a USB integrado. Esto es para mantener el Pro Trinket pequeño y económico, puede usar cualquier cable FTDI para conectar al puerto FTDI para una conexión en serie. nnection es solo para cargar código nuevo. El gestor de arranque en Pro Trinket usa 4KB de FLASH, por lo que el tamaño máximo de boceto es de 28,672 bytes. El gestor de arranque no afecta el uso de RAM...
