RFD900X Data Link Set UAV Data Radio Data Transmission Module For PPM SBUS Singal Forwarding GH1*25

Attention:
The new version of the firmware already supports SBUS remote control signal forwarding. You can download the 3.14 version of the firmware from the official website to update it. You need to download the latest RFDTools-V2.36.zip software to update and configure the firmware. SBUS signal is set to send and receive on the P1.1 port (non-reserved P1.3), check GPO1_1SBUSIN on the ground end, and select the SBUS output type under GPO1_1SBUSOUT for the air end, generally SBUS1 or SBUS1/2.

A single terminal is equipped with a UART cable, suitable for additional pairs and multi-point users. The so-called lock and no lock are just the difference between wiring. You can choose according to the type of flight control plug connected (for Pixhawk commonly uses two types of plugs), other flight controllers or serial communication devices need to DIY wiring.
