Adafruit Feather M0 Express ATSAMD21 Cortex M0 POL_Electronics Prototyping With this Feather we're getting

With this Feather we're getting a little nostalgic for the ATmega328P - the classic 'Arduino' chip - with this Adafruit Feather 328P running at 3

Programmable RGB LED and controlled by GPIO45

Software Configurable Resolution Settings

5mm TRS connector is included as an alternative to easily insert an audio cable

Really it\'s quite small

Adafruit Feather M0 Express ATSAMD21 Cortex M0 POL_Electronics Prototyping With this Feather we're gettingAt the Feather M0's heart is an ATSAMD21G18 ARM Cortex M0+ processor, clocked at 48 MHz and at 3. 3V logic, the same one used in the new Arduino Zero . This chip has a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x as much)! This chip comes with built in USB so it has USB to Serial program & debug capability built in with no need for an FTDI like chip. Please note that while this board was our first for CircuitPython
