    Adafruit Analog Output K-Type Thermocouple Amplifier - AD849

    -Titulo Original : Adafruit Analog Output K-Type Thermocouple Amplifier - AD8495 Breakout [ADA1778]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1778 // Stock Type: Sensors >> Temperature // In Stock & Ready to Ship // Thermocouples are very sensitive, requiring a good amplifier with a cold-compensation reference. We have a couple digital thermocouple amplifiers in the shop already from Maxim. Now we're happy to introduce an excellent analog-output amplifier. This is a very simple sensor to use, and if your microcontroller has analog input capability, you'll be ready to go really fast! The AD8495 K-type thermocouple amplifier from Analog Devices is so easy to use, we documented the whole thing on the back of the tiny PCB. Power the board with 3-18VDC and measure the output voltage on the OUT pin. You can easily convert the voltage to temperature with the following equation: Temperature = (Vout - 1.25) / 0.005 V. So for example, if the voltage is 1.5VDC, the temperature is (1.5 - 1.25) / 0.005 = 50°C Each order comes with a 2 pin terminal block (for connecting to the thermocouple), a fully assembled PCB with the AD8495 + TLVH431 1.25V precision voltage reference, and pin header (to plug into any breadboard or perfboard).

    Adafruit DC Motor and Stepper FeatherWing Add-on For All Fea

    -Titulo Original : DC Motor and Stepper FeatherWing Add-on For All Feather Boards-Fabricante : ADAFRUIT-Descripcion Original: 4 full H-Bridges: the TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC. // Up to 4 bi-directional DC motors with individual 12-bit speed selection (so, about 0.02% resolution) // Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping. // Big 3.5mm terminal block connectors to easily hook up wires (18-26AWG) and power // Polarity protected 2-pin terminal block and jumper to connect external power, for separate logic/motor supplies // A Feather board without ambition is a Feather board without FeatherWings! This is the DC Motor + Stepper FeatherWing which will let you use 2 x bi-polar stepper motors or 4 x brushed DC motorx (or 1 stepper and 2 DC motors). Using our Feather Stacking Headers or Feather Female Headers you can connect a FeatherWing on top or bottom of your Feather board and let the board take flight! The original Adafruit Motorshield Kit is one of our most beloved kits, which is why we decided to squish it all together on a FeatherWing to make something even smaller, lighter, and more portable! Instead of using a latch and the Arduino's PWM pins, we have a fully-dedicated PWM driver chip onboard. This chip handles all the motor and speed controls over I2C. Since the FeatherWing only uses the I2C (SDA & SCL pins), it works with any and all Feathers- ATmega32u4, ATSAM M0 or ESP8266-based. You can stack it with any other FeatherWing or with itself (just make sure you have each wing with a unique I2C address). Comes with an assembled & tested FeatherWing, terminal blocks & plain header. Some soldering is required to assemble the headers on. Stacking headers not included, but we sell them in the shop so if you want to stack shields, please pick them up at the same time. Feather and motors are not included but we have lots of motors in the shop. You can use any DC or stepper motors that run from 4.5-13.5VDC and draw under 1.2A (3A peak) per coil. You'll likely also need to provide some external power supply for your motors, since its not suggested you run motors from the Feather's lipoly battery. Please note that unlike the full sized shield, there's no servo connections (they wouldnt fit!) So if you need a bunch of servos, check out our 8-channel Servo Featherwing.

    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...

These chips take a serial input (SPI) of 1 byte (8 bits) and then output those digital bits onto 8 pins. You can chain them together so putting three in a row with the serial output of one plugged into the serial input of another to make 3 x 8 = 24 digital outputs. You can chain pretty much as many as you want. This makes it easy to control a lot of outputs like LEDs from only 3 digital microcontroller pins. This item contains ! These chips similarly to the more well known 7HC595s but they are high power drains, able to sink 150mA per pin. They cannot source current so they should be connected to LED cathodes. This makes them ideal for use with LED matrices where you end up sinking 8 or more LEDs at once. These chips are DIP package so you can easily plug them into any breadboard or perfboard with 0.1 spacing. They are not the same pinout as '595s so check the datasheet!

    -Titulo Original : Adafruit (PID 1497) Software Defined Radio Receiver USB Stick - RTL2832 w/R820T-Fabricante : ADAFRUIT-Descripcion Original: Packed with the powerful RTL2832U and R820T tuner // Can tune into signals from 24MHz to 1850MHz // Includes a basic 'DVB-T' antenna // If you've ever been curious about software defined radio (SDR), this USB stick is the easiest way possible to have fun with a powerful, configurable receiver. Packed with the powerful RTL2832U and R820T tuner, it can tune into signals from 24MHz to 1850MHz. That means you can use a computer (with Windows, Mac, or Linux) to tune into: FM Radio, AM signals (but not AM radio), CW (morse code!), unencrypted radio signals (such as those used by many police and fire departments), POCSAG pagers, and more. We plugged it into our windows computer and used Zadig+SDR# to poke around and listen to the wireless world around us, it's lots of fun! Please visit adafruit website for more information Comes with a very compact (but very good quality) RTL2832+R820T module with an MCX RF connector, and a basic 'DVB-T' antenna (used to tune into DVB TV signals, not available in the US but will work in Europe or any country with DVB-T broadcasts) as well as an IR remote which isn't terribly useful. The antenna seems OK for basic experimentation. We also have some MCX to BNC and MCX to SMA adapters (see below) which you may want to use to connect a better antenna. Please note! Depending on your location, listening in to some radio signals may not be legal. So consider this your warning to check before 'accidentally' tuning into naughty frequencies...

  • Adafruit SGP30 Air Quality Sensor Breakout - VOC and eCO2 (3
    Precio:  $3,725.00

    Adafruit SGP30 Air Quality Sensor Breakout - VOC and eCO2 (3

    -Titulo Original : Adafruit SGP30 Air Quality Sensor Breakout - VOC and eCO2 (3709)-Fabricante : ADAFRUIT-Descripcion Original: fully integrated MOX gas sensor // output signals with a typical accuracy of 15% // This part will measure eCO2 // Breathe easy with the SGP30 Multi-Pixel Gas Sensor, a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing and fully calibrated output signals with a typical accuracy of 15% within measured values. The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals. This is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running our library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C. The SGP30 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching. This part will measure eCO2 (equivalent calculated carbon-dioxide) concentration within a range of 0 to 60,000 parts per million (ppm), and TVOC (Total Volatile Organic Compound) concentration within a range of 0 to 60,000 parts per billion (ppb). Please note, this sensor, like all VOC/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources! That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use. Another nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC/eCO2 values...
  • Adafruit Stereo 2.1W Class D Audio Amplifier - TPA2012
    Precio:  $2,179.00

    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.

    Adafruit 24-Channel 12-bit PWM LED Driver - SPI Interface -

    -Titulo Original : Adafruit 24-Channel 12-bit PWM LED Driver - SPI Interface - TLC5947 [ADA1429]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1429 // Stock Type: Breakout Boards >> PWM Drivers // In Stock & Ready to Ship // For all of you out there who want to control 24 channels of PWM, we salute you! We also would like you to check out this breakout board for the TLC5947 PWM driver chip. This chip can control 24 separate channels of 12-bit PWM output. Designed (and ideal) for LED control, this board is not good for driving servos. If you need to drive servos, we have a controller for that over here . Only three SPI pins are required to send data (our Arduino library shows how to to use any digital microcontroller pins). Best of all, the design is completely chainable. As long as there's enough power for all the boards you can chain as many as you'd like, like a little trail of blue PCBs stretching out into the sunset. Each of the 24 output's is constant-current and open drain. You can drive multiple LEDs in series, with a V+ anode supply of up to 30V. If you want to drive something that requires a digital input, you must use a pullup resistor from the drive pin to your logic level to create the full waveform. One resistor is used to set the current for each of the outputs, the constant current means that the LED brightness doesn't vary if the power supply dips. We use a 3.3K resistor for about 15mA but you can solder a thru-hole resistor over it if you'd like to change that value. Check the TLC5947 datasheet for details on resistor-to-current values. We include a few extras to make this board easy to use: a durable 5V low-dropout regulator (with reverse polarity protection in case y'know, you plug it in backwards), a green power-good LED, four mounting holes and a current-set resistor. A bit of 0.1 header is also included so you can solder it on and plug into a breadboard. To use: Power V+ with 5-30VDC, and connect ground to the common ground. Then send 3-5V logic SPI data on DIN (data in), CLK (clock) and LAT (latch). If you'd like to quickly turn off all the outputs, raise th...

    Adafruit Green 7-segment clock display - 0.56 digit height [

    -Titulo Original : Adafruit Green 7-segment clock display - 0.56 digit height [ADA813]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 813 // Stock Type: LEDs >> Segmented // In Stock & Ready to Ship // Design a clock, timer or counter into your next project using our pretty 4-digit seven-segment display. These bright crisp displays are good for adding numeric output. Besides the four 7-segments, there are decimal points on each digit and an extra wire for colon-dots in the center (good for time-based projects). These are ultra bright 125mcd! You can drive these with less current to get the same brightness to save power, or crank them up to 20mA and have them really bright. These displays are multiplexed, common-cathode. What that means it that you can use a 74HC595 or just 8 microcontroller pins if you can spare them to control the 8 anodes (7-seg + decimal) at about ~15mA each, and then connect NPN transistors or a TPIC6B595 to the cathodes to sink the 8*20mA = ~120mA maximum per digit. These come in a bright green color, we also have many other sizes and colors...

Its also easy to use. Simply plug in the gold plated contacts into any USB port and a 3.7V/4.2V lithium polymer or lithium ion rechargeable battery into the JST plug on the other end. There are two LEDs - one red and one green. While charging, the red LED is lit. When the battery is fully charged and ready for use, the green LED turns on. Seriously, it could not get more easy. Charging is performed in three stages: first a preconditioning charge, then a constant-current fast charge and finally a constant-voltage trickle charge to keep the battery topped-up. The charge current is 100mA by default, so it will work with any size battery and USB port. If you want you can easily change it over to 500mA mode by soldering closed the jumper on the back, for when you'll only be charging batteries with 500mAh size or larger. For use with Adafruit LiPoly/LiIon batteries only! Other batteries may have different voltage, chemistry, polarity or pinout.Comes assembled and tested with a free bonus JST cable!5V input via PCB-style USB connectorFor charging single Lithium Ion/Lithium Polymer 3.7/4.2v batteries (not for older 3.6/4.1v cells)100mA charge current, adjustable to 500mA by soldering a jumper closedFree 2-pin JST cable included!The MicroLipo charger can get hot during charging.
