Hi all,

i have a RasPi 3 with an attached DAC+ Board.

For an ambilight project (http://powerpi.de/atemberaubendes-ambilight-am-eigenen-tv-selber-bauen-raspberry-pi-2-tutorial-teil-1/) i need to attach some cables to PIN 9, 19 and 23.

Questions: Are these Pins allready used by DAC +?

How to connect to them? If the DAC is attached i can not solder to the Pins?

 

Sorry, if you think this is a stupid question.

 

Thanks and best regards

  Hi,

  check out this documentation:
  https://www.hifiberry.com/build/documentation/gpio-usage-of-hifiberry-boards/

  You can solder a pin header or cables directly onto the DAC+. There is seconds row of connectors that are connected in parallel to the Raspberry Pi GPIO. Note that soldering onto the board will void the warranty.

  Best regards,
