Note: This board comes with loose headers, so soldering is required. please take EXTRA PRECAUTION while doing soldering works. We don't want you to get burnt.
Feather is the new development board from Adafruit, and like its namesake, it is thin, light, and lets you fly! We designed Feather to be a new standard for portable microcontroller cores.
This is the Adafruit Feather M0 Adalogger - an 'all-in-one' Cortex M0 datalogger (or data-reader) with built-in USB and battery charging. It's 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. 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.
To make it easy to use for portable projects, Adafruit added a connector for any of our 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 it is available. The battery is also tied thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
Features and specifications:
- Measures 2.0" x 0.9" x 0.28" (51mm x 23mm x 8mm) without headers soldered in

- 256KB of FLASH + 32KB of RAM
- No EEPROM
- 3.3V regulator with 500mA peak current output
- USB native support comes with a USB bootloader and serial port debugging
- You also get tons of pins - 20 GPIO pins
- Hardware Serial, hardware I2C, hardware SPI support
- 8 x PWM pins
- 10 x analog inputs
- 1 x 10-bit analog output (DAC)
- Built-in 100mA lipo charger with charging status indicator LED
- Pin #13 red LED for general purpose blinking
- Power/enable pin

The Feather M0 Adalogger uses the extra space left over to add MicroSD + a green LED:
- Pin #8 green LED for your blinking pleasure
- MicroSD card holder for adding as much storage as you could possibly want, for reading or writing.
Comes fully assembled (but header pins are not soldered) and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE. Some header is also tossed in so you can solder it in and plug into a solderless breadboard. Lipo battery, MicroSD card, and USB cable are not included.
- 1 x Adafruit Feather Cortex-M0 Adalogger board
- 2 x 16 pins header
