Hi, I have a HKPilot 500mW Transceiver Telemetry Radio Set V2 (433Mhz) and would like to add OSD. I have Apm 2.8 and the telem port is occupied by the HK unit (above)
Is it possible to to use the one port for both? i.e. splice in to wires? any help would be greatly appreciated. Feel free to answer as though talking to a child.
Im arfaid, but you have to open the case to get the UART 0 or 2 connector for change the Telemetry port.

It is not suitable to split serial connectors.
Telemetry need fixed UART adresses.
If you don´t want to solder on the board, change to Pixhawk. It have more connectors.
You save a lot of time.
