Re: SBitx: Capacitor across gpio's tx line

 

Hi Gary,

Thank you for the links.? They do provide more information than what is on the Raspberry Pi site.

I still do not understand the issue with C66.? None of the documentation lists a maximum capacitance load.? Some of the examples given in online recommendations suggest using capacitors to help reduce contact bounce, which leads me to believe that it is not that C66 is too much of a load on the GPIO output.? That means there is a circuit issue that I do not understand.
