Are you the kind of person who doesn't like taking down the skeletons and spiders until after January? Well, we've got the development board for you. This is electronics at its most spooky! The Adafruit HalloWing is a skull-shaped ATSAMD21 board with a ton of extras built in to make for an adorable wearable, badge, development kit, or the engine for your next cosplay or prop.
You're a human! Right? For now anyway... There's a red pulsing in the distance... NO! A ZOMBIE! You're losing health, but what's this? A white pulsing from around a corner, a healer! You'll stay human for a little longer... We've written up a fun game for you to play with Circuit Playground Express and CircuitPython or MakeCode. Hopefully you'll be a human long enough to check out this guide!
Easy e-paper finally comes to microcontrollers, with this breakout that's designed to make it a breeze to add a tri-color eInk display. Chances are you've seen one of those new-fangled 'e-readers' like the Kindle or Nook. They have gigantic electronic paper 'static' displays - that means the image stays on the display even when power is completely disconnected. The image is also high contrast and very daylight readable. It really does look just like printed paper!
It's what you've been waiting for, the Feather M4 Express featuring ATSAMD51. This Feather is fast like a swift, smart like an owl, strong like a ox-bird (it's half ox, half bird, OK?) This feather is powered by our new favorite chip, the ATSAMD51J19 - with its 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset.
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!
You already have Git setup, and you have a GitHub account. You want to contribute to an open source project like CircuitPython, but you're not sure where to start. This guide walks through the steps from forking your first repo to your GitHub account, to cloning it locally, creating a working branch, making a commit, pushing your code to your fork, creating a PR, and both receiving and giving a review. You'll learn good practices and tips and tricks, and before you know it, you'll be a pro contributor. Pick a project, find an issue, and let's get started!
What's smaller than a Feather but larger than a Trinket? It's an Adafruit ItsyBitsy M4 Express featuring the Microchip ATSAMD51! Small, powerful, with a ultra fast ATSAMD51 Cortex M4 processor running at 120 MHz - this microcontroller board is perfect when you want something very compact, with a ton of horsepower and a bunch of pins. This Itsy is like a bullet train, with it's 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will zig and zag and zoom, and with a bunch of extra peripherals for support, this will for sure be your favorite new chipset.
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!
ItsyBitsy M0 Express is only 1.4" long by 0.7" wide, but has 6 power pins, 23 digital GPIO pins (12 of which can be analog in, 1x analog out, and 13x PWM out). It's the same chip as the Arduino Zero and packs much of the same capability as an Adafruit Metro M0 Express or Feather M0 Express but really really small. So it's great once you've finished up a prototype on a Metro M0 or Feather M0, and want to make the project much smaller. It even comes with 2MB of SPI Flash built in, for data logging, file storage, or CircuitPython code.
