A over-powerful mini microcontroler for Arduino IDE / CircuitPython based on ATSAMD21 Cortex M0

The Trinket M0 from Adafruit is small but incredibly powerfull! It's a tiny microcontroller board propelling the ATSAMD21, this little Atmel chip offers a bunch of power and ressources to your project. This board is designed to to be small enough to fit into any project and low cost to use it everywhere without getting worry about the price. Keep your expensive development board for prototyping and use this mini-microcontroler to turn your project into a final setup.
The Trinket M0 is the cheaper CircuitPython programmable board!

This new Trinket keeps the same form-factor than those used for the ATtiny85-based Trinket... the same size but seriously upgraded. On the Trinket M0, a ATSAMD21E18 Cortex M0 did replaced the ATTiny-85. The ATSAMD is smaller, easy to use to also allow you to do more with this single chip.

Arduino IDE compatible: the most interesting feature of Trinket M0 is that it can program it with Arduino IDE. Like the Trinket, Feather and many other Adafruit's board, you can leverage the power of Arduino environnement with your favorite board :-)

CircuitPython ready: The board is delivred with CircuitPython flashed on the board. CircuitPython is de tuned MicroPython including tons of stuff to facilitate electronic prototyping with python script. The board will show up as a very small disk having a file on it. Edit the to add python code with your with your favorite text editor and you are ready to make your electronic project running with python code. Python is one of the most popular programming language in the world.
With CircuitPython, no need for installs, no need for IDE, no need for compiler! You just need a computer, even ChromeBooks able to edit text file. When you're done, just unplug the Trinket M0 and your code will go with you. Please check out the Trinket M0 CircuitPython guide for a list of capabilities and quick-start code examples - CircuitPython is easier to code but not as low-level and complete as Arduino.

Here are some of the updates you can look forward to when using Trinket M0:

  • Same form-factor : same size and same pinout than classic Trinket
  • ATSAMD21E18 32-bit Cortex M0+ instead of ATtiny85 8-bit AVR
  • Flash 256KB : 32x as much as 8 KB on ATtiny85
  • RAM 32 KB : 64x as much as 512 bytes on ATtiny85
  • Clock: 48 MHz 32 bit processor : 6x as fast as ATtiny85 (not even taking into account 32-bit speedups)
  • Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts. (ATtiny85 does not have native USB)
  • Can be used with Arduino IDE or CircuitPython
  • LEDs:
    • Green ON LED
    • Red pin #13 LED
    • LED RGB DotStar LED
  • All 5 GPIO pins are available and are not shared with USB - so you can use them for whatever you like!
    • Five GPIO pins with digital input/output with internally connected pullups or pulldowns
    • Three of the I/O pins can be used for 12-bit analog input
    • True analog output on one I/O pin - can be used to play 10-bit quality audio clips
    • We gave the M0 pads the exact same names as the original Trinket so all your existing Arduino code will work exactly the same as-is without changes
    • Two high speed PWM outputs - for servos, LEDs, etc
    • Three pins can also be used as hardware capacitive touch sensors with no additional components required
    • Can drive NeoPixels or DotStars on any pins, with enough memory to drive 8000+ pixels. DMA-NeoPixel support on one pin so you can drive pixels without having to spend any processor time on it.
    • Native hardware SPI, I2C and Serial available on two pads so you can connect to any I2C or Serial device with true hardware support (no annoying bit-banging). You can have either one SPI device or both I2C and Serial.
  • Same Reset switch for starting your project code over
  • Power with either USB or external output (such as a battery) - it'll automatically switch over
  • Size: 27 x 15.3 x 2.75mm (3.5mm height with microUSB)
  • Weight: 1.4g

This board is really very small and still include mounting holes!


For each order, you will receive a Trinket M0 fully assembled and tested with Circuit Python flashed on the board and example code programmed on the board.
