This incredibly small stereo amplifier is surprisingly powerful - able to deliver 2 x 2.1W channels into 4 ohm impedance speakers (@ 10% 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% efficient when driving an 8Ω 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!
Feather is the new development board from Adafruit, and like it's namesake it is thin, light, and lets you fly! 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' ESP8226 WiFi development boardwith built in USB and battery charging. Its an ESP8266 WiFi module with all the extras you need, ready to rock!
Add lots of touch sensors to your next microcontroller project with this easy-to-use 8-channel capacitive touch sensor breakout board, starring the CAP1188. This chip can handle up to 8 individual touch pads, and has a very nice feature that makes it stand out for us: it will light up the 8 onboard LEDs when the matching touch sensor fires to help you debug your sensor setup.
CircuitPython is the best new way to code microcontrollers. But what if you want to run that same code on a more POWERFUL computer like a Raspberry Pi (or really any Linux SBC?) Well now you can - take advantage of the wide collection of drivers and example code we have for CircuitPython and now you can run it right on your Pi!
This TFT display is big (2.8" diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive or capacitive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
New to CircuitPython? Looking for an easy way to get started? We've written a library for the Circuit Playground Express that makes it super simple to begin using all the sensors, switches and lights. This guide will show you all the features of this library and how to use each one. Let's get coding!
This little USB port go-between is like a speed gauge for your USB devices. Instead of hauling out a multimeter and splicing cables, plug this in between for a quick reading on how much current is being drawn from the port. Great for seeing the charge rate of your phone or tablet, checking your battery chargers, or other USB powered projects.
Now you can add eInk displays to your favorite single-board Linux computers! This tutorial will show you how to wire and run the RePaper eInk displays in the Adafruit shop on a Raspberry Pi or BBB. Learn how to assemble and program the RePaper eInk Development Board. These daylight readable displays are excellent for data-logging applications, outdoor displays, or any other ultra-low power project.
