Version of openXsensor to be used with expressLRS
This project is foreseen to generate telemetry data to a ELRS receiver when a flight controller is not used.
It can provide
* up to 4 analog voltages * the altitude and the vertical speed when connected to a pressure sensor (optional) * GPS data (longitude, latitude, speed, altitude,...) (optional)
This project requires a board with a RP2040 processor (like the rapsberry pi pico).
A better alternative is the RP2040-Zero (same processor but smaller board): https://www.waveshare.com/rp2040-zero.htm
This board can be connected to:
a pressure sensor (GY63 or GY86 board based on MS5611) to get altitude and vertical speed
a GPS from UBlox (like the beitian bn220)
some voltage dividers (=2 resistors) when the voltages to measure exceed 3V
