Its an ESP8266 WiFi module with all the extras you need, ready to rock! We have other boards in the Feather family, check'em out here. At the Feather HUZZAH's heart is an ESP8266 WiFi microcontroller clocked at 80 MHz and at 3.3V logic. This microcontroller contains a Tensilica chip core as well as a full WiFi stack. You can program the microcontroller using the Arduino IDE for an easy-to-run Internet of Things core. We wired up a USB-Serial chip that an upload code at a blistering 921600 baud for fast development time. It also has auto-reset so no noodling with pins and reset button pressings. To make it easy to use for portable projects, we added a connector for any of our 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. Here's some handy specs!

    Adafruit Electret Microphone Amplifier - Max4466 With...

    -Titulo Original : Adafruit Electret Microphone Amplifier - MAX4466 with Adjustable Gain [ADA1063]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1063 // Stock Type: Sensors >> Sound/Noise // In Stock & Ready to Ship // Add an ear to your project with this well-designed electret microphone amplifier. This fully assembled and tested board comes with a 20-20KHz electret microphone soldered on. For the amplification, we use the Maxim MAX4466, an op-amp specifically designed for this delicate task! The amplifier has excellent power supply noise rejection, so this amplifier sounds really good and isn't nearly as noisy or scratchy as other mic amp breakouts we've tried! This breakout is best used for projects such as voice changers, audio recording/sampling, and audio-reactive projects that use FFT. On the back, we include a small trimmer pot to adjust the gain. You can set the gain from 25x to 125x. That's down to be about 200mVpp (for normal speaking volume about 6 away) which is good for attaching to something that expects 'line level' input without clipping, or up to about 1Vpp, ideal for reading from a microcontroller ADC. The output is rail-to-rail so if the sounds gets loud, the output can go up to 5Vpp! Using it is simple: connect GND to ground, VCC to 2.4-5VDC. For the best performance, use the quietest supply available (on an Arduino, this would be the 3.3V supply). The audio waveform will come out of the OUT pin. The output will have a DC bias of VCC/2 so when its perfectly quiet, the voltage will be a steady VCC/2 volts (it is DC coupled). If the audio equipment you're using requires AC coupled audio, place a 100uF capacitor between the output pin and the input of your device. If you're connecting to an audio amplifier that has differential inputs or includes decoupling capacitors, the 100uF cap is not required. The output pin is not designed to drive speakers or anything but the smallest in-ear headphones - you'll need an audio amplifier (such as our 3.7W stereo amp) if you want to connect the amp directly to speakers . If you're connecting to a microcontroller pin, you don&...

    -Titulo Original : Adafruit (PID 2423) PiTFT Plus 320x240 2.8 TFT + Capacitive Touchscreen-Fabricante : ADAFRUIT-Descripcion Original: PiTFT Plus 320x240 2.8" TFT+Touchscreen for Raspberry Pi Zero, Pi3, Pi2 or Model A+, B+ (any Pi with a 2x20 connector) // 320x240 3.5" TFT touchscreen LCD // Custom kernel available at Adafruit // The display uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24 // Is this not the cutest little display for the Raspberry Pi? It features a 2.8 display with 320x240 16-bit color pixels and a capacitive touch overlay. That's right, instead of a resistive touchscreen, which requires a fingernail or stylus, you can now use a fingerpad. The screen looks much nicer, with a black bezel and glass overlay. If you don't need a capacitive touchscreen, check out the resistive touch version. This updated design fits perfectly onto the Pi Zero, Pi 3, Pi 2 or Model A+, B+! (Any Pi with a 2x20 connector) Not for use with an old Pi 1 with 2x13 connector If you'd like to use a 2.8 display with the original Pi A or Pi B, check out the Model B version. This version also has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath. Now that it's the same outline as a Pi 3/2/B+ it fits well on top of a Pi in our Raspberry Pi Enclosure base and can use our faceplate for a compact touchscreen Pi The display and touchscreen uses the hardware I2C Pins (SDA & SCL), SPI pins (SCK, MOSI, MISO, CE0) as well as GPIO #25 and #24. All other GPIO are unused and you can still share the I2C pins with sensors, LED drivers, etc. Since we had a tiny bit of space, there's 4 slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface. For example, you can use one as a power on/off button. Use it for console access or easily pop up X11 onto the PiTFT for a mini monitor, although its rather small at 320x240. Instead, we recommend using PyGame or other SDL-drawing programs to write onto the frame buffer. Raspberry Pi computer and enclosure not included!

    Adafruit PID 2030 PowerBoost 1000 Basic 5V USB Boost 1000ma

    -Titulo Original : Adafruit (PID 2030 PowerBoost 1000 Basic - 5V USB Boost @ 1000mA from 1.8V+-Fabricante : ADAFRUIT-Descripcion Original: Synchronous operation means you can disconnect the output completely by connecting the ENable pin to ground. This will completely turn off the output // 4A internal switch means you can get 1000mA+ from as low as 1.8V, 1500mA+ from 2 NiMH or Alkaline batteries, and at least 2000mA from a 3.7V LiPoly/LiIon battery or 3 NiMH/Alkalines. Just make sure your batteries can actually supply the required 2-4A, OK? // Low battery indicator LED lights up red when the voltage dips below 3.2V, optimized for the most common usage of LiPo/LiIon battery usage // On-board 1000mA charge-rate 'Apple/iOS' data resistors. Solder in the included USB connector and you can plug in any iPhone or iPod for a speedy 1000mA charge rate. Works with iPads, both mini and 'classic' type. // Full breakout for battery in, control pins and power out 90%+ operating efficiency in most cases (see datasheet for efficiency graphs), and low quiescent current: 5mA when enabled and power LED is on, 20uA when disabled (power and low batt LED are off) // PowerBoost is the perfect power supply for your power-hungry portable project! This little DC/DC boost converter module can run from 1.8V batteries or higher, and convert that voltage to 5.2V DC for running your 5V projects. With a beefy 4A DC/DC converter, it can give you 1A+ from as low as 2V. Like our popular 5V 1A USB wall adapter, we tweaked the output to be 5.2V instead of a straight-up 5.0V so that there's a little bit of 'headroom' long cables, high draw, the addition of a diode on the output if you wish, etc. The 5.2V is safe for all 5V-powered electronics like Arduino, Raspberry Pi, or Beagle Bone while preventing icky brown-outs during high current draw because of USB cable resistance. The PowerBoost 1000 has at the heart a TPS61030 boost converter from TI. This boost converter chip has some really nice extras such as low battery detection, 4A internal switch, synchronous conversion, excellent efficiency, and 700KHz high-frequency operation. Check out these specs! Great for powering your robot, Arduino project, single-board-computer such as Raspberry Pi or BeagleBone! Each order comes with one fully assembled and tested PCB, a loose 2-PH JST jack, a 2-pin Terminal block and a loose USB A jack. If you are powering your project from USB, solder the USB A jack in (a 3-minute soldering task). Then choose either JST for input (JST is often used for our LiIon batteries, but the connector is only rated for 2A) or a terminal block. The 1000 version comes with a 2-pin terminal block so you can solder it to the output spot where the USB jack would go. Or don't solder any connectors in for a more compact power pack and go with 22AWG wires soldered directly in...

    -Titulo Original : Adafruit Barcode Reader/Scanner Module - CCD Camera - USB Interface [ADA1203]-Fabricante : ADAFRUIT-Descripcion Original: Adafruit Part Number: 1203 // Stock Type: Sensors >> Readers/Scanners // In Stock & Ready to Ship // Decode nearly any kind of 1D (striped) barcode in your project using this adorable compact barcode scanner. We've looked all over for a small, light, low-power module that can be easily integrated. This OEM scanner has a little camera inside that takes 100 photos per second, instead of using a 'scanning mirror' assembly. This means its less likely to get damaged or out of alignment. Please note: this is a camera-based not laser-based scanner - you'll have to hold it farther away than you usually do for laser-mirror scanners! Try 10cm/4 or more distance with the button held down. This all in one module is the simplest we could find. On the end is just a USB cable, plug it into any computer (or microcomputer such as BeagleBone, Raspberry Pi, etc) and it will show up as an HID keyboard. When a barcode is scanned, the raw data is decoded, parity-checked and spit out as if they were typed on a keyboard. Like all barcode scanners, you can do some basic configuration by powering it up and 'scanning' in special barcodes in the manual. For example you can change the delay between 'typed' characters, or what the terminating character, if any, should be. Check the download tab for the printable manual. If you'd like to set up the scanner to be different than the default, print it out on plain white paper and scan each 'configuration' code. The config will be saved to non-volatile memory so you only have to do it once. This reader will read a wide variety of barcode standards. The most common ones such as CODE39 and UPC are supported out of the box. To enable some of the rarer standards, check the manual as you may have to 'scan configure' to enable it.

    Teensy 3.2 With Pins

    -Titulo Original : Teensy 3.2 with pins-Fabricante : PJRC-Descripcion Original: Teensy 3.2 and 3.1 have exactly the same pinout. // Teensy 3.2 provides more power on its 3.3V pin, and accepts a wider voltage input range. // The Teensy is a breadboard-friendly development board with loads of features in a, well, teensy package. The Teensy 3.2 brings a 32 bit ARM Cortex microprocessor into the mix so you can do some serious number crunching. The Teensy 3.2 comes pre-flashed with a bootloader so you can program it using the on-board USB connection: No external programmer needed! You can program for the Teensy in your favorite program editor using C or you can install the Teensyduino add-on for the Arduino IDE and write Arduino sketches for Teensy! The processor on the Teensy also has access to the USB and can emulate any kind of USB device you need it to be, making it great for USB-MIDI and other HID projects. The 32 bit processor brings a few other features to the table as well, such as multiple channels of Direct Memory Access, several high-resolution ADCs and even an I2S digital audio interface! There are also 4 separate interval timers plus a delay timer! Oh yeah, and all pins have interrupt capability. Also, it can provide system voltage of 3.3V to other devices at up to 100mA. All of this functionality is jammed into a 1.4 x 0.7 inch board with all headers on a 0.1 grid so you can slap in on a breadboard and get to work! On top of everything else the Teensy has been gifted with more RAM (64K, thats 4x more than the Teensy 3.0) and 256kb of flash memory! The Teensy 3.2 now now has 5V tolerance on its digital inputs however all analog-only pins are still 3.3V only. Teensy 3.2 adds a more powerful 3.3 volt regulator, with the ability to directly power ESP8266 Wifi, WIZ820io Ethernet and other power-hungry 3.3V add-on board...
