2HP Expander (USB-A)

2HP expander adding a USB-A host port, MIDI out and two trigger jacks ยท beau-seidon

Clone of Expander for the Ornament and Crime Teensy 4.1 build. Pairs with the 14HP Ornament and Crime Teensy 4.1 panel in the same folder. Some fabs will not cut the rectangular USB-A slot unless you add a note to the order. The repo has no license file, though the readme says the O_C T4.1 design is CC BY-SA 4.0.
