This chip has 32K of flash and 2K of RAM, with built in USB so not only does it have a USB-to-Serial program \u0026amp; debug capability built in with no need for an FTDI-like chip, it can also act like a mouse, keyboard, USB MIDI device, etc.\u003c\/p\u003e\n\u003cp\u003eTo make it easy to use for portable projects, Adafruit added a connector for any of their 3.7V Lithium polymer batteries and built in battery charging. You don't need a battery, it will run just fine straight from the micro USB connector. But, if you do have a battery, you can take it on the go, then plug in the USB to recharge. The Feather will automatically switch over to USB power when its available. They also tied the battery thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.\u003c\/p\u003e\n\u003cp\u003eHere's some handy specs!
