Simple DIY Electronic Music Projects presents the design for a MiniDexed IO board for the Raspberry Pi 5 which supports four GY-PCM5102 modules as described here: RPi 5 Quad Stereo Sound with PCM5102A.
This is based on my MiniDexed Raspberry Pi IO Board including provision for a SSD1306 OLED display, two buttons, MIDI IN, OUT and optional THRU and a rotary encoder.
It includes connections for four GY-PCM5102 modules using the four I2S lanes of the Raspberry Pi 5, but note that it is not intending to use the built-in 3.5mm stereo output of any of the PCM5102 modules but instead will hook up additional 3.5mm TRS sockets to the audio L/R/GND additional pins.
The design allows for either DIN or TRS MIDI sockets. The DIN sockets are mounted underneath the PCB whereas the TRS sockets (if used) will be on top with the other components.
Check out the design in the post here.
