Adafruit Trinket M0 - for use with CircuitPython and Arduino IDE

The Adafruit Trinket M0 is a tiny microcontroller board, built around the Atmel ATSAMD21, a little chip with a lot of power. 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 Adafruit's lowest-cost CircuitPython programmable board! It is the same form factor as the original ATtiny85-based Trinket. 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 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 Trinket M0 and your code will go with you. Five GPIO pins with digital input/output with internally connected pullups or pulldowns Three of the I/O pins can be used for 12-bit analog input True analog output on one I/O pin - can be used to play 10-bit quality audio clips
