The Adafruit Gemma M0 is a super small microcontroller board, with just enough built in to create many simple projects.

It may look small and cute: round, about the size of a quarter, with friendly alligator clip sew pads. But do not be fooled! The Gemma M0 is incredibly powerful! We've taken the same form factor we used for the original ATtiny85 based Gemma and gave it an upgrade.

The Gemma M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 powerhouse. The Gemma M0 will super charge your wearables! It's just as small, and it's easier to use, so you can do more.

The most exciting part of the Gemma 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 main.

py on it. Edit main.

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 Gemma M0 and your code will go with you.

Here are some of the updates you can look forward to when using Gemma M0:

Each order comes with one fully assembled and tested Gemma M0 with CircuitPython example code programmed in.

So what are you waiting for? Pick up a Gemma M0 today and be amazed at how easy and fast it is to get started with Gemma and CircuitPython!
