Hi,

Just installed and configured the Dac Pro from Raspberry. It works but now the colors inside the case don’t function anymore. Is this a common issue and resolvable?

There are shared pins.

Please note that the SPI’s GPIO10 pin cannot be reassigned, as the RGB signal is directly connected to this pin (which serves as the SPI’s MOSI line).

If you connect another module that also uses the SPI MOSI pin (GPIO10), a pin conflict will occur. This can cause the RGB LEDs to malfunction, and you will have to choose only one of the two devices to work at a time—they cannot operate simultaneously.
