Adafruit Trinket M0 - for use with CircuitPython & Arduino IDE

Description

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. We wanted to design 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 our lowest-cost CircuitPython programmable board!
We've taken the same form factor we used for  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, we are shipping it with CircuitPython on board. When you plug it in, it will show up as a very small disk drive with  on it. Edit  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.  - CircuitPython is easier to code but not as low-level and complete as Arduino.
Each order comes with one fully assembled and tested Trinket M0 with CircuitPython & example code programmed in.
So what are you waiting for? Pick up a Trinket M0 today and be amazed at how easy and fast it is to get started with Trinket and CircuitPython!
