Adafruit Trinket M0 Development Board

Adafruit Trinket M0 Development Board is a tiny easy-to-use microcontroller board small enough to fit into any project without hesitation. This development board retains the same size (27mm x 15.3mm x 2.75mm / 1.07" x 0.6" x 0.1"), form-factor, and pinout as classic Trinket.

The Trinket M0 is built around the Atmel ATSAMD21E18 powerhouse and can be used with Arduino IDE or Adafruit's CircuitPython. The Trinket M0 board is equipped with for coding using Python in any text editor of the user's choice. This eliminates the need for any software installs, IDE, or compilers.
