orange_hand Posted April 25, 2012 Report Share Posted April 25, 2012 Hi Guys, I was wondering what the following two pins in the encoder footprint are used for ? Cheers orange Quote Link to comment Share on other sites More sharing options...
nILS Posted April 25, 2012 Report Share Posted April 25, 2012 For encoders with included switch (would work as a shift button if your encoders had it). Quote Link to comment Share on other sites More sharing options...

orange_hand Posted April 26, 2012 Author Report Share Posted April 26, 2012 Hi, another question that came to my mind. Would it not be possible to use those connections to supply the voltage for the LED's for the encoders ? Cheers orange Quote Link to comment Share on other sites More sharing options...
nILS Posted April 26, 2012 Report Share Posted April 26, 2012 Well, one pin is ground and the other is 5V via a 10k resistor. That'll give you 0.5mA if you connect a LED to it. Not a lot ;) If you replaced the resistor with something smaller you'll get more current, but you'll also feed the shift register... So, in short, I'd rather not do it.

That was clear, without cutting the tracks it wont work. But if the 5V would be sourced directly, it would be easier to provide the power for the LEDs, so no flying wires would be required....
