This is the Adafruit Feather M0 Adalogger – our take on 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, 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 a built-in USB so it has a 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, we 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’s available. We 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.
Note: The package does not include SD Card. You have to purchase it separately.
