Feather M4 Express ATSAMD51

Description

Feather M4 Express ATSAMD51. Based on the ATSAMD51J19 – with its 120MHz Cortex M4 with floating point support and 512KB Flash and 192KB RAM. Your code will run blazing fast on this chipset. This feather form factor fits the featherwings, so you can quickly get started with extensions. The Feather M4 is compatible with the Arduino IDE and runs very fast with it. It ships with CircuitPython onboard. When you plug it in, it appears as a tiny 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 installations, IDE, or compiler required, so you can use it on any computer, even ChromeBooks or computers where you can't install software. When you're done, unplug it and your code comes with you.
