At the heart of the Feather M0 is an ATSAMD21G18 ARM Cortex M0 processor. It is clocked at 48MHz and runs at 3.3V logic, the same one used in the 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 also comes with built-in USB. So it has built-in USB-to-serial programming and debugging capabilities. All without the need for an FTDI-like chip.
For ease of use in portable projects, a connector has been added for 3.7V lithium polymer batteries and a built-in battery charger. You don't need a battery, it works fine straight from the micro USB connector. But if you do have a battery, you can take it with you on the go and then plug in the USB to charge. The Feather will automatically switch to USB power when it's available.The battery is also connected to an analog pin via a splitter, so you can measure and monitor the battery voltage to detect when it needs to be charged.
