Radxa ZERO3E PDM

#1

Hello,

I noticed that the Rockchip RK3566 SoC supports Pulse Density Modulation (PDM) for audio input. However, I couldn’t find specific information in the datasheet about which GPIO pins are assigned to the PDM interface. Could someone clarify whether the PDM interface is accessible through the GPIO pins on the Radxa Zero? If so, which pins are designated for this function?

I really appreciate your help,
best regards

Sorry, the ZERO 3E does not have the PDM connector out on the 40 PIN.
But there are I2S related PIN pins, you can refer to this link:
