The Adafruit Trinket M0 may be small, but do not be fooled by its size! It’s a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. Adafruit designed a microcontroller board that was small enough to fit into any project, and low cost enough to use without hesitation. Perfect for when you don’t want to give up your expensive dev-board and you aren’t willing to take apart the project you worked so hard to design. It’s one of the lowest-cost CircuitPython programmable boards!
Adafruit used the same form factor for the original ATtiny85-based Trinket and gave it an upgrade. The Trinket M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse. It’s just as small, and it’s easier to use, so you can do more.
The most exciting part of the Trinket M0 is that while you can use it with the Arduino IDE, it ships with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with code.py on it. Edit code.py with your favorite text editor to build your project using Python, the most popular programming language. No installs, IDE or compiler needed, so you can use it on any computer, even ChromeBooks or computers you can’t install software on. When you’re done, 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:
Each is fully assembled and tested Trinket M0 with CircuitPython & example code programmed in.

This is the latest stable release of CircuitPython that will work with the Trinket M0.
Start here if you are new to CircuitPython.
This is the latest unstable release of CircuitPython that will work with the Trinket M0.
Unstable builds have the latest features but are more likely to have critical bugs.
Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
