PIN REFERENCE: Adafruit Feather M0 Express #PrettyPins

Here’s a pin reference for the Adafruit Feather M0 Express in PNG format. A PDF vector version resides in the corresponding PCB repository on GitHub.

When you need more than just a pin number for simple input or output, diagrams like these reveal a board’s hardware peripheral multiplexing options — PWM outputs, analog channels, SPI ports and so forth.

In the past such diagrams were painstakingly produced by hand, but now we’re dabbling in automating some of that process, coalescing data from Fritzing and the CircuitPython and Arduino core source code. It’s less prone to typos and gives a more consistent look across all Adafruit boards.

More to come!
