Yes I saw that. I believe the 'A' on the 4 pads is NOT the pad a referred to in the text. SOLVED thanks Mike again, I've checked and reflow the solder joint on the X4R pin (on the back side) that come loose pheraphs with too many hits or wasn't good from the beginning, and now fixed with hot glue. ...

That's my point. That is the SBUS (servo output) signal from the Rx, not the SPort (telemetry input) signal. The telemetry input looks to be a point on a 3-pin component from something I found on the web. I'll check at home and keep you posted, maybe I've confused picture! This was my resource: htt...

Double checking here, but you have connected the UART6 signal to the SPort (non-inverted) place rather than the SBUS connection, haven't you? Thanks Mike for your help. I've connected the TX of UART6 (configured in Betaflight as Smartport) of my FC, an F4 board that doesn't do inversion to the A po...

Is the most used in quads

I know well the good soul JB... RX is slightly different, but is exactly my case. I can't do discovery on 9X, and I don't see A4 and Cbat value

The SPort signal is inverted serial data. Does the FC send inverted data? No, F4 chip doesn't have an inverter, so you have to connect directly an UART TX (in my case uart6) to A port on X4R-SB http://cdna3.zoeysite.com/Adzpo594RQGDpLcjBynL1z/cache=expiry:31536000/resize=fit:max,width:1200/compress...

Hi all, I'm a new user and this is my first post because I've a problem, maybe is just an already answered question, and I'm sorry for open a new topic, so you can address me to the solution. My setup is this: TGY 9X stock board M64 THR e AIL mod done (2 res 220k to pin 41 and 42) Telemetry mod done...
