I have now created a schematic & working rats nest prototype board (but for reliability, I’ll order a ‘proper’ PCB). If there’s any interest I’ll publish the details.
Edit: This is a board for an LED system that is already powered & fused, so this design is purely a controller, not for power distribution. It used the WT32-ETH01 board, a Pmod I2S2 line-in ADC and a INMP441 I2S circular microphone module.
