DolphinRC RC Link Transponder
Voltage:2-6S BEC: 5V 3A
RX:Support PPM/CRSF
TX:ELRS transmitter supports CRSF
TX:TBS transmitter supports CRSF or PPM
Recommend different frequencies for RX and TX
For example ELRS 2.4GHz RX and ELRS/TBS 915MHz TX
---------
If using ELRS-ELRS is very simple:
On rx: no change
On
tx: review the hardware and look for a UART. This depends on the TX, but many have a UART inside and outside. For example, on Radiomaster Bandit there is an external JST mount for the UART. On Radiomaster Nomad the uart will be inside.
Put the TX into wifi mode. Go to 10.0.0.1/hardware
.
Update the hardware json file and change the CRSF serial pins from SPort to 3 (rx) and 1 (tx)
This is the pin standard for serial uart on ELRS tx
RX TX + -
This is a uart for the 3 and 1 pins
If you wire this to another rx or tx you can make the relay work.
