Description

Description

Feather is a new Adafruit development board. As its name suggests, this board is small and light ... like a feather! Adafruit designed Feather to become a new standard for portable microcontroller projects.

Here is the Adafruit Feather M0 Adalogger - with which you get a Cortex M0 (all-in-one) datalogger (or data-reader) including USB support and integrating a charging circuit for Lipo battery.
This version of the Adafruit Feather M0 with a microSD connector is ready to do battle! We have other boards in the Feather family, see our range

At the heart of a Feather M0, you'll find an ARM Cortex M0 ATSAMD21G18 processor, clocked at 48 MHz and 3.3V logic, the same as that used on the new Arduino Zero. This chip has a large FLASH memory of 256K (8x more than on an Atmega328 or 32u4) and 32K of RAM memory (16x more than on a Uno)! This chip integrates USB support and therefore has USB-to-Serial and debugging support functionality without having to use an additional FTDI component.

To make it easier to integrate into your portable projects, Adafruit has added a connector to connect a 3.7v Lithium polymer battery (with the possibility of recharging the battery). If you don't need the battery, you can power it directly from the USB port. On the other hand, if you have a battery, you can plug it in and recharge it by plugging a power source into the USB port. The Feather will automatically select the power source between the USB port and the battery depending on what is available. The battery is also connected to an analog input via a voltage divider bridge so that it is possible to monitor the battery voltage and to indicate to the user that it's time to connect the board via USB to recharge the battery.

The Feather M0 Adalogger has enough free space to allow the addition of a MicroSD connector + a green LED:

  • Pin # 8 equipped with a green LED (which you can flash as desired)
  • MicroSD support to add huge storage space for your read and write operations.

Content

Comes fully assembled and tested, with a USB bootloader so that it is possible to get started quickly with Arduino IDE. The board is delivered with some connectors (pinHeader) which you can weld on the board to be able to insert it in a breadboard. The Lipoly battery, MicroSD card and USB cable are not included (but we have these elements on our WebShop!)
