It supports CircuitPython out of the box for instant coding on any computer, including Chromebooks, and offers USB and GPIO connectivity. Compatible with all FeatherWing add-ons, it includes a built-in Mini NeoPixel and 2MB SPI Flash storage, making it ideal for rapid prototyping and advanced embedded projects. ## Description 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. And best of all, it's a Feather - so you know it will work with all our FeatherWings! What a great way to quickly get up and running. The most exciting part of the Feather M4 is that while you can use it with the Arduino IDE - and it's bonkers fast when you do, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with main.py on it. Edit main.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can't install software on. When you're done, unplug the Feather and your code will go with you. The Feather M4 Express uses the extra space left over to add a Mini NeoPixel, 2 MB SPI Flash storage and a little prototyping space. You can use the SPI Flash storage like a very tiny hard drive. When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files. When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with our helper program, access the files over USB. Review: Powerful processor. Excellent support in the Arduio development envionment. - Excellent SAMD51 board with great support. The only option I found with 12-bit analog in AND out!
