Following on from my previous post, can anyone tell me if I can connect directly together a Pixhawk 4 Mini and a R1 clone receiver to enable Yaapu telemetry over S.Port. The Pixhawk Mini is 3.3V on the telemetry pins and the R1 looks to be the same or is it 5v TTL.? and would need a MAX232.
Obviously I still need a the diode to βmixβ the two TX and RX on the telemetry to the single pin S.port.
