This is the Adafruit Feather M0 Adalogger - Adafruit's take on an 'all-in-one' Cortex M0 datalogger (or data-reader) with built in USB and battery charging. Its an Adafruit Feather M0 with a microSD holder ready to rock! At 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.
