GY PCM5102 DAC module
This inexpensive DAC module can be found on AliExpress and other places like eBay for very little money. It features the Texas Instruments PCM5102A on a small breakout board with integrated 3.5mm jack.
The module has four solder-pad jumpers on the back which must be set correctly before sound will be produced. Some boards arrive with no jumpers soldered at all, or configured incorrectly, so be sure to check it and (re)solder the pads.
Ensure your board is configured as shown in the picture above, that is:
- 1 = L
- 2 = L
- 3 = H
- 4 = L
Connect your module to the Raspberry Pi as follows:
