A minimal ESP32 telemetry solution is an ESP32-WROOM-xx wired directly to the FC and powered by 3v from the FC. Simple and incredibly lightweight. Initial programming is done with a snap-in interface to the module. Then it gets wired in.
It would be great to be able to update the firmware over the air, rather than having to unsolder and remove the module. Mav8266 already has OTA updates.
