Adafruit HalloWing M0 Express Board | DigiKey Daily

Adafruit’s HalloWing—a play on Halloween—M0 Express board is a skull-shaped ATSAMD21 board with a ton of extras built-in to make for an attractive wearable, badge, development kit, or the engine for your next costume or prop. On the board’s front side is a 1.44-inch sized 128 by 128 full-color TFT display. The four fang teeth, below the display, are the analog and capacitive touch inputs with large alligator-clip holes. This board comes with Adafruit’s default example code that has a spooky eye demo running in glorious color. In technical terms, this board is a tricked-out Feather M0 Express with rearranged pins. Also, it has both Arduino and CircuitPython build support so you can pick your favorite development language.
