FRM303 is a multi-function high performance RF module in compliance with the AFHDS 3 third generation automatic frequency hopping digital system protocol. It features an external replaceable single antenna, support of bi-directional transmission, three power supply methods, support of voltage alarm function in case of external power supply, and support of inputting PPM, S.BUS and UART signals.
Adaptive devices — PPM: devices that can output standard PPM signals, such as FS-TH9X, FS-ST8, FTr8B receiver; S.BUS: devices that can output standard S.BUS signals, such as FS-ST8, FTr8B receiver; closed source protocol 1.5M UART: PL18; open source protocol 1.5M UART: EL18; open source protocol 115200 UART: devices that can output open source protocol 115200 UART signal.
Compatible combinations: PL18 + FRM303 + FGPZ01 adapter, EL18 + FRM303 + FGPZ03 adapter, ST8 + FRM303 + FGPZ03 adapter, PL18 Ultra + FRM303 + FGPZ03 adapter, FRM303 + FGPZ02 adapter. Supports ELRS.
