Adafruit Trinket M0 Development Board is a tiny easy to use microcontroller board that is 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 theAtmel ATSAMD21E18 Cortex M0+ powerhouse and can be used with Arduino IDE or Adafruit's CircuitPython. The Trinket M0 board is equipped with main.py for coding using Python in any text editor of the user's choice. This eliminates the need for any software installs, IDE, or compilers.
The ATSAMD21E18 32-bit Cortex M0+ feature 256KB flash, 32KB RAM, and 48MHz speedups. The native USB of this Trinket M0 board is supported by every OS and can be used in Arduino or CircuitPython as USB serial console. This development board offers built-in LEDs and five General Purpose IO (GPIO) pins that are not shared with USB for multipurpose usage. The Trinket M0 board is designed with native hardware SPI, I2C, and serial on two pads for true hardware support.
