it sounds a bit strange but I have realised that one SMD part is mising on my KISS FC board. I have bought it “used” and maybe it was aleady gone or I have desoldered it when soldering the pins of the voltage supply.
It is the small SMD part next to the “minus” input at the VIN. It is located between VIN “minus” and the edge of the processor.
PS: Do not regard the marked areas of this pic, I just took this by chance…. 😉
The result of this “gap” is that the “pitch” signal is missing, thats what I have realised after a few hours.
Could somebody help me in identfying the SMD brick?
I know it will be not easy to install it, but I would try it….
