Adafruit GEMMA M0 - Miniature wearable electronic platform

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, but do not be fooled - Gemma M0 is incredibly powerful! The Gemma M0 has swapped out the lightweight ATtiny85 (Gemma V2) for a ATSAMD21E18 and it comes with CircuitPython on board.

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.

Specifications:
- Same size, form-factor, and pinout as classic Gemma
- Updating ATtiny85 8-bit AVR for ATSAMD21E18 32-bit 48 MHz Cortex M0+ processor with 256KB Flash and 32 KB RAM
- Native USB supported by every OS - can be used in Arduino or CircuitPython as USB serial console, Keyboard/Mouse HID, even a little disk drive for storing Python scripts
- Can be used with Arduino IDE or CircuitPython
- Built in RGB DotStar LED
- Three big-hole sew-pads can be used for conductive thread or alligator-clips for fast prototyping
- Each I/O pad can be used for 12-bit analog input, or digital input/output with internally connected pullups or pulldowns
- M0 pads have the exact same names as the original Gemma so all your existing Arduino code will work exactly the same as-is without changes
- True analog output on one I/O pad - can be used to play 10-bit quality audio clips
- Two high speed PWM outputs on other two I/O Pads - for servos, LEDs, etc
- All three pads can also be used as hardware capacitive touch sensors with no additional components required
- Can drive NeoPixels or DotStars on any pins, with enough memory to drive 8000+ pixels. DMA-NeoPixel support on one pin so you can drive pixels without having to spend any processor time on it.
- Native hardware I2C or Serial available on two pads so you can connect to any I2C or Serial device with true hardware support (no annoying bit-banging)
- Reset switch for starting your project code over
- On/Off switch built in
- JST battery connector for plugging in AAA's or LiPoly battery (no built-in LiPoly charging so it is safe to use with NiMH/Alkalines)
