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.
