NEW GUIDE: Adafruit Feather M4 Express #Feather @MicrochipMakes #SAMD51


The newest member of the Adafruit Feather Microcontroller ecosystem is here!

It’s what you’ve been waiting for, the Feather M4 Express featuring the Microchip Technology 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.
