The board is probably powered by USB, because if the whole point is to emulate a keyboard and type in the numbers, then you're going to have USB anyways.

- alias_neo 7y agoNot necessarily, ESP32 has WiFi and Bluetooth so you could emulate a Bluetooth keyboard or so something entirely different using WiFi. But yes, I suspect USB like you suggest.
- unwind 7y agoUh, the actual article says it's USB, and talks about HID implementation and so on. No need to second-guess anything.
