Feather is a development board from Adafruit, and like its namesake it is thin, light, and lets you fly! Adafruit designed Feather to be a new open standard for portable microcontroller cores.
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. It is an Adafruit Feather M0 with a microSD holder ready to rock! Adafruit has other boards in the Feather family here
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.
To make it easy to use for portable projects, Adafruit added a connector for 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. The battery is tied thru a divider to an analog pin, so you can measure and monitor the battery voltage to detect when you need a recharge.
Here’s some handy specs! Like all other Feather M0’s you get:
The Feather M0 Adalogger uses the extra space left over to add MicroSD + a green LED:
Comes fully assembled and tested, with a USB bootloader. Includes some header so you can solder it in and plug into a solderless breadboard.

This is the latest stable release of CircuitPython that will work with the Feather M0 Adalogger.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the Feather M0 Adalogger.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
