2026-06-29 (M) EWC_Mobile EasyEDA schematic

I decided to create a schematic for the MIDI controller, but I left off the addressable LEDs. The first version I wanted to make would use a premade light bar with eight lights. Each input had a 10KΩ pull-up resistor, and the circuit was mostly inputs, with six encoders, each with three digital inputs because it had an integrated pushbutton. There were also a couple of keyswitches. EasyEDA had the necessary footprints, but the hardest to align was the microcontroller demo board. Fortunately, I found it by name, although I could not verify the version number. I did not include the MIDI port in my first sketch, but I will add a 3.5mm headphone jack to transmit digital notes. All power will come from the USB port.
