Description

An Arduino Zero (M0) compatible or CircuitPython compatible designed for embedded project

At MC Hobby we really love all the Feathers products. But this Feather is very special. It's the very first Feather that is specifically designed for use with CircuitPython! CircuitPython is a beginner-oriented flavor of MicroPython developed by Adafruit Industries - and as the name hints at, its a small but full-featured version of the popular Python programming language specifically for use with circuitry and electronics.

CircuitPython is still in beta (may 2017) and Adafruit is working hard to make it awesome!

You cant also use the Feather M0 Express with Arduino IDE! The Feather M0 is propeled by a  ARM Cortex M0+ ATSAMD21G18 processor. Clocked at 48 MHz with a 3.3V logic, this board is technically the same than a Arduino Zero. This chip has a large FLASH memory of  256K (8x more than the Atmega328 or 32u4) and 32K of RAM memory (16x as much)!
This chip does also have a natif support for USB so it has USB-to-Serial program and debug capability without the need of a FTDI-like chip.

Here is some speficiations

  • Measures 51mm x 23mm x 8mm - without headers soldered in
  • Light: 5 grams
  • ATSAMD21G18 @ 48MHz
  • 3.3V logic/power
  • 256KB of FLASH + 32KB of RAM
  • No EEPROM
  • 32.768 KHz crystal for clock generation & RTC
  • Voltage regulator 3.3V (500mA peak current output)
  • USB native support
  • Comes with USB bootloader and serial port debugging
  • 20 GPIO pins
  • Hardware Serial, hardware I2C, hardware SPI support
  • PWM outputs on all pins
  • 6 x 12-bit analog inputs (0 to 4095)
  • 1 x 10-bit analog ouput (DAC, 0 to 1023)
  • Built in 100mA lipoly charger + charging status indicator LED
  • USER LE on pin #13 (red)
  • Power/enable pin
  • 4 mounting holes
  • Reset button

The Feather M0 Express uses the extra space left over to add:

  • a Mini NeoPixel,
  • 2 MB SPI Flash storage
  • a little prototyping space.

You can use the SPI Flash storage like a very tiny hard drive.
When used in CircuitPython, the 2 MB flash acts as storage for all your scripts, libraries and files.
When used in Arduino, you can read/write files to it, like a little datalogger or SD card, and then with Adafruit's helper program, access the files over USB.

Comes fully assembled and tested, with a USB bootloader that lets you quickly use it with the Arduino IDE or for loading CircuitPython. We also toss in some header so you can solder it in and plug into a solderless breadboard.

Technical details

  • Dimension: 51.0mm x 22.8mm x 7.3mm
  • Poids: 4.7gr
