Adafruit Trinket M0 - for use with CircuitPython & Arduino IDE

The Adafruit Trinket M0 is a compact but powerful microcontroller board, designed around the Atmel ATSAMD21 chip. Despite its small size, it's a powerhouse, offering much more than you'd expect from a board this tiny. Perfect for projects where you need a low-cost, efficient solution without sacrificing performance, the Trinket M0 is Adafruit's lowest-cost CircuitPython-programmable board.

Taking the original ATtiny85-based Trinket and upgrading it, the Trinket M0 swaps the 8-bit ATtiny85 with the powerful ATSAMD21E18, a 32-bit Cortex M0+ processor. It maintains the same small form factor and is easier to use, allowing you to accomplish more.

One of the standout features is its native support for CircuitPython, making it incredibly easy to use. When plugged in, the Trinket M0 appears as a small disk drive containing a file. You can easily edit this file on any computer, even Chromebooks, without needing additional software or installations. Once you're done, unplug it and take your code with you.

Key Features:

• Same size, form factor, and pinout as the classic Trinket.
• 32-bit Cortex M0+ processor running at 48 MHz, 6x faster than the ATtiny85.
• 256KB Flash and 32KB RAM, significantly more storage and memory than the ATtiny85.
• Native USB support, enabling USB serial console, HID devices (Keyboard/Mouse), or a small disk drive for storing Python scripts (unlike the ATtiny85).
• Compatible with Arduino IDE and CircuitPython.
• Built-in green ON LED, red pin #13 LED, and RGB DotStar LED.
• All 5 GPIO pins are available and can be used for digital input/output with pull-ups or pull-downs.
• True analog output on one pin, ideal for playing 10-bit quality audio clips in Arduino.
• PWM outputs for driving servos or LEDs.
• Capacitive touch sensing on 3 pins, no extra components needed.
• Can drive NeoPixels or DotStars on any pin, with support for up to 8000+ pixels.
• Hardware SPI, I2C, and Serial support for seamless device connections.
• Easy reset switch to restart your project.
• Powers via USB or external sources (automatically switches between them).
• Mounting holes for convenient placement in projects.

Each Trinket M0 comes fully assembled with CircuitPython pre-loaded, and includes example code to help you get started immediately. Whether you're creating a small gadget or expanding a larger project, the Trinket M0 makes coding and building easier and faster than ever before!
