Every time I looked at a development board that had USB A plug integrated into its PCB, I saw the teeth of a skull. So one night when I couldn't sleep, I fired up Inkscape, drew a rectangle and three ellipses, and made this.
Once I had it imported into Fritzing, I had to decide what components to put on it. I could simply make it an USB light, with two LEDs in the eyes. Or I could make it play a melody, like the #Nyan Board. In the end, I decided to just put a SAMD21 chip on it, and make it equivalent to an Adafruit Gema M0.
Once the PCBs arrive, I will make a board definition for CircuitPython for it.
