Can I use an ESP32 microcontroller to convert a terminal Model M to USB?
« on: Sat, 26 October 2019, 14:36:20 »
I don't have a Teensy and don't really want to buy one unless I absolutely have to. I do however have two ESP32 microcontrollers and was wondering if I can use these to convert the terminal output of the Model Ms to USB. I'm assuming it's physically possible, but has anyone done it? Is there any code already written? Thanks!

The Model M uses 5V logic level and the ESP32 uses 3.3V, so converter circuitry would be needed.
There is Bluetooth HID firmware out there for the ESP32, but you would probably have to port TMK's terminal protocol code to the ESP32.

I think it would be easier and probably cheaper to just get a $5 Pro Micro and flash it with TMK's or Soarer's converter firmware.
