Topic: K resistor value at 3.3v positive

Does anyone know what the "k" resistor is on the circuit board. It is right at the 3.3v power input.

Could you post a picture. I have a stock board just collecting dust now but I see no resistor near the 3.3v input.

Bottom Resistor labeled "K" is R57 and top one is R47

You have one of the newer boards. Those are just zero ohm resistors that are being used as fuses to my knowledge. Based off of other post where they have been burned. The second rev boards like mine do not have them

Hmm. a while back I soldered a zero ohm resistor there and it made one of the diodes turn off furthering more problems to my board.

Its not the best soldering job but that resistor is zero ohms.

I found these on mouser, I'm not sure if they are the right fuses one is a 1206 and the other is a 0603 series 437 and 438
