I am trying to use an off brand arduino nano from a hackpack to convert the ir robot into an rc robot. I haven’t got any sign of info from my RadioMaster RP3 ELRS Receiver 2.4GHz ExpressLRS Nano receiver. I found a zz-cat CRSF library on GitHub but it doesn’t like my arduino. Any thought on where to connect it and how to read the channels?
No clue as to what you are asking. Post annotated schematic showing how you have wired this. Include all power, ground and power source connections. Include links to all of the hardware items showing technical information. Explain what is sending what and what is expected on the receive end.
