FC Receiver Wiring Help Needed

[King kwad]

Hello everyone,

I am building my first quad and i am having trouble connecting my receiver. So I have a SP Racing F3 V1 Flight controller and I don't know where i should wire my FrySky XSR Receiver? Any help would be greatly appreciated.

Thanks,

You want to use UART3, which is pin 3 on the IO_2 connector. You can get ground and 5V from pin 1 and 2 on the same connector.

I don't have a plug for the IO_2 connector is their a way i can solder the wires on? and where can i connect the telemetry?

They are JST SH connectors, according to the manual. Next thing is the pin count. I.e, "JST SH 7 pin", etc. Should be easy to find on amazon, just look and make sure that it's the right shape- there are a few types of JST connector out there in the wild.

There are UART1 & 3 headers as well, though I know on my clone SPF3 the UART3 header doesn't work. These are shown in the manual I linked. Definitely worth trying.

Will using this connector and splicing the receiver wires to it work?

 

[ElectriSean]

That should work, as long as the connector seats properly. I'd also use a dab of hot glue on the connector just to be safe.

Excellent! And just to double check the telemetry goes to to pin 4? Thanks for your help!

 

[ElectriSean]

No, telemetry will have to go to a different UART.

Okay Thanks for help!
