Overview
The RadioMaster SBUS Wireless Trainer Module is a wireless trainer module designed to link an instructor radio and a student radio without using a trainer cable. It transmits the trainer signal via SBUS for a flexible, cable-free training setup and is configured through the trainer menu in EdgeTX.
Compatibility is based on using a receiver that supports a 5V SBUS serial output. For student radios with built-in ExpressLRS modules, recommended receivers include RadioMaster RP1/RP2. For radios with an internal 4-in-1 multi-protocol module or CC2500 module, the recommended receiver is the RadioMaster R81 V2.
