We designed Feather to be a new standard for portable microcontroller cores. This is the Adafruit Feather HUZZAH ESP8266 - our take on an 'all-in-one' ESP8266 WiFi development board with built in USB and battery charging. 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.

    Adafruit I2S MEMS Microphone Breakout - SPH0645LM4H (3421)

    -Titulo Original : Adafruit I2S MEMS Microphone Breakout - SPH0645LM4H (3421)-Fabricante : ADAFRUIT-Descripcion Original: small, low cost MEMS mic with a range of about 50Hz - 15KHz // there are three digital pins: // The microphone is a single mono element // This I2S MEMS microphone is bottom ported // MEMS mics can detect sound and convert it to voltage // Listen to this good news - we now have a breakout board for a super tiny I2S MEMS microphone. Just like 'classic' electret microphones, MEMS mics can detect sound and convert it to voltage, but they're way smaller and thinner. This microphone doesn't even have analog out, its purely digital. The I2S is a small, low cost MEMS mic with a range of about 50Hz - 15KHz, good for just about all general audio recording/detection. The microphone is a single mono element. You can select whether you want it to be on the Left or Right channel by connecting the Select pin to power or ground. If you need stereo, pick up two microphones! You can set them up to be stereo by sharing the Clock, WS and Data lines but having one with Select to ground, and one with Select to high voltage. This I2S MEMS microphone is bottom ported, so make sure you have the hole in the bottom facing out towards the sounds you want to read. It's a 1.6-3.6V max device only, so not for use with 5V logic (its really unlikely you'd have a 5V-logic device with I2S anyways). Many beginner microcontroller boards don't have I2S, so make sure its a supported interface before you try to wire it up! This microphone is best used with Cortex M-series chips like the Arduino Zero, Feather M0, or single-board computers like the Raspberry P...

Besides, all the interfaces of HUSKYLENS are reserved for your convenience. // In addition, the surface of the silicone sleeve is coated with the matte oil, so it is not easy to stain, and has a smooth feel, which brings you a better experience. // Note: This product does not include the HUSKYLENS board. // What's the HUSKYLENS? HuskyLens is an easy-to-use AI Machine Vision Sensor. It is equipped with multiple functions, such as , , , , , and . HuskyLens adopts the new generation of specialized AI chip Kendryte K210. The performance of this special AI chip is 1,000 times faster than that of the STM32H743 when running neural network algorithm. With these excellent performances, it is capable of capturing even fast-moving objects.With the HuskyLens, your projects have new ways to interact with you or environment, such as interactive gesture control, autonomous robot, smart access control and interactive toy. There are so many new applications for you to explore. AI Machine Vision Sensor HuskyLens is designed to be smart. It has the built-in machine learning technology that enables HuskyLens to recognize faces and objects. Moreover, by long pressing the learning button, HuskyLens can continually learn new things even from different angles and in various ranges. The more it learns, the more accurate it is. Compatible with Arduino, RPi, etc. Through the UART / I2C port, HuskyLens can connect popular main control boards like Arduino, micro:bit, Raspberry Pi and LattePanda to help you make very creative projects without playing with complex algorithms. Easy to Use - Just Press the Button! HuskyLens is pretty easy-to-use. You can change various algorithms by pressing the function button. Click the learning button, HuskyLens starts learning new things. After that, HuskyLens is able to recognize them. Comes with IPS Screen HuskyLens carries a 2.0 inch IPS screen. So you don’t need to use a PC in the parameters tuning. Enjoy the convenience it brings, what you see is what you get! New Ways to Interact with HuskyLens Interative Gesture Control HuskyLens' object-tracking skills can be used to learn specific gestures. It is able to recognize those learned hand movement patterns and feed their positions. With these data, creating awesome interactive projects are never so easy. Autonomous Vehicle HuskyLens can detect and follow lines. It provides a new way to do line following: simply click the button, then it starts learning and tracking new lines. Let's enjoy the fun of making with HuskyLens! Robotic Eyes HuskyLens can be eyes of robots. which allows your robot to recognize you, understand your hand gesture commands, or help you put stuff in order and so on. With Huskylens, nothing is impossible!

    Precio:  $5,659.00

    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...
