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
