Description
Feather M0 Basic Proto ATSAMD21 based on the ATSAMD21G18 ARM Cortex M0 processor clocked at 48MHz and running at 3.3V logic, the same as used in the new Arduino Zero. This chip sports a whopping 256K of FLASH (8x more than the Atmega328 or 32u4) and 32K of RAM (16x more)! This chip also comes with built-in USB, so it has USB to Serial and debugging capabilities without the need for an FTDI-like chip.
