Apart from preparing the audio module there is not much soldering involved. All the components are plugged together with jumper wires and put into the case.

If you are also using the CMJCU-5102 module, you will have to <a href="https://blog.sengotta.net/connecting-a-pcm5102a-breakout-board-to-a-raspberry-pi/">pull the XMT pin to high by connecting it to the 3.3V pin via a 10 k&#8486; resistor.</a> This will unmute the audio output. Also, the FLT, DMT, SCL and FMT pins should be <a href="images/IMG_20190122_120812.jpg" data-fancybox data-caption="While not being the nicest soldering job known to man, the connection of the FLT, DMT, SCL and FMT pins to GND serves its purpose.">connected to the module's GND pin on the backside</a>. That way, only a single cable connection to GND on the Raspberry Pi is needed.
