ELRS

Glossary

CRSF: TBS Crossfire, more specifically in our case most often referring to the communication protocol between

TX and TX module and
RX and FC respectively

Supported receiver protocols: CRSF, SBUS, SUMD, HoTT Telemetry, MAVLink, and PWM
ExpressLRS is written in C++ using the Arduino framework.
