Adafruit GEMMA M0 - Miniature wearable electronic platform
- Same size, form-factor, and pinout as classic Gemma
- 256K of FLASH and 32K of RAM
- 48 MHz 32 bit processor - 6x faster than ATtiny85
- Native USB supported by every OS (ATtiny85 does not have native USB)
- Can be used with Arduino IDE or CircuitPython.
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! Adafruit took the same form factor they used for the original ATtiny85-based Gemma and gave it an upgrade. The Gemma M0 has swapped out the lightweight ATtiny85 for a ATSAMD21E18 (48MHz with 3.3V logic/power) 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, it is shipped 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.
