Adafruit ItsyBitsy M4 Express featuring ATSAMD51

Nice compact easy to use circuitPython equipped micro. Had to update the bootloader and the circuitPython but that was expected and pretty easy to do.

Amazing tiny Arduino

This Arduino is both tiny AND powerful. After soldering it into the heart of my project I am very pleased with it's quality and performance! It's even at a great price from Little Bird. I can recommend Adafruit to anyone looking for quality products for their projects.
