Feather of the Day: Adafruit Feather M0 Adalogger #Feather @MicrochipMakes

The Adafruit Feather ecosystem is so rich with hardware diversity, we wanted to share them, one each day. Today is the Adafruit Feather M0 Adalogger!

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. Its 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 Arduino Zero. This chip has 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.

Here’s some handy specs! Like all Feather M0’s you get:

  • Measures 2.0″ x 0.9″ x 0.28″ (51mm x 23mm x 8mm) without headers soldered in
  • Light as a (large?) feather – 5.3 grams
  • ATSAMD21G18 @ 48MHz with 3.3V logic/power
  • 256KB of FLASH + 32KB of RAM
  • No EEPROM
  • 3.3V regulator with 500mA peak current output
  • USB native support, comes with 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 lipoly charger with charging status indicator LED
  • Pin #13 red LED for general purpose blinking
  • Power/enable pin
  • 4 mounting holes
  • Reset button
  • Programmable with Arduino

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.
