X4r 4Ch flash to s-port

Post by nick9one1 » Sat Aug 10, 2019 2:54 pm

I have an X4R 4Ch module (the one without sbus).

Is it possible to flash this and get sbus?

It looks like there are only 2 firmwares available, EU and non-EU?

They both run the same firmware, the difference is done in hardware by the placement of a 0-Ohm resistor on the board (the connector pin for CH4 either connects to the SBUS signal or the CH4 one). If you're able to solder very small things you can change it.
