Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0 info

Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0 has a free prototyping space on the board. Feather is a new development board series from Adafruit. As the name suggests, Feather boards are thin and light. Feather is designed to be a new standard for open source development platforms.

Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0 is based on ATSAMD21G18 ARM Cortex M0 processor clocked at 48 MHz and at 3.3V logic. This chip also used in the Arduino M0 series. ATSAMD21G18 has 256K flash and 32K RAM and built in USB support. Therefore this chip has USB-to-Serial program & debug capability readily (and there is no need for an FTDI-like chip).

For easy use in portable projects, Adafruit added a connector suitable for their 3,7V Lithium polymer batteries and built in battery charging. There is no need for a battery, the board can be powered directly from the micro USB connector. If you want to use it with a battery, you are also free to run your project with a battery and then plug in the USB for the battery to be recharged. Feather boards will automatically switch over to USB power when it is available. The battery is also tied through a divider to an analog pin, so it is possible to measure and monitor the battery voltage and detect when it needs a recharge.

Adafruit Feather M0 Basic Proto - ATSAMD21 Cortex M0 has some extra space left over, so a tiny little prototyping area is left free on the board. If you just need to attach a button or sensor, you can use this prototyping area directly instead of wiring them from the breadboard.

The board has a USB bootloader, so you can use it with the Arduino IDE. The pack also includes some headers for you to solder them and use in your projects or on your breadboard.

Note: USB cable and Li-Po battery are not included.
