Fs-ia6b connected with sp racing f3 problem

[Ardzej]

Hi i connected receiver to fc, controller is binded with receiver but when im in betaflight nothing happens in ,receiver' overlap, of course all setting are made for ibus connect

It looks like you are using the 8 pin connector IO_2! It might be better to use UART2 which is close to the usb and labelled uart2. Check the pins before you plug the rx in. Then set the rx in BF.
Hope that helps?

meybe you know which pin is gnd +5 and signal? uart 2 have 4 pins

It would appear that you can use the 8 pin connector that you are using.
On the connector you are using:
1 = GND
2 = VCC
3 = CH3 (UART3 rx)
Then make sure that uart3 is selected in the ports tab as the serial rx. UNLESS uart is for USB!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Then on the config page select flysky and ibus.
That should get you up and running?

Thanks for helping me,
if i understand i have to connect here?

It should work with the connector as you had it in the initial photos. Just make sure you set the correct uart in the ports tab to be a serial rx then in config set serial rx flysky and ibus. Then you should be fine.
