The most exciting part of the ItsyBitsy M0 is that while you can use it with the Arduino IDE, it's 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. When you're done, unplug the Itsy' and your code will go with you.
