I want to connect UMA-16 mic array to MCHStreamer

Both of them have PDM interface, so I think it can be connected.

Could you bring a detailed guide for it?

should I link PDM_CLK(J3-16) of UMA-16 to PDM_CLK(J3-11) of MCHStreamer?
or PDM_CLK0(R27B) to PDM_CLK(J3-11) & PDM_CLK4(R16B) to PDM_CLK2(J3-12) of MCH?

For information sake for others who might want to do the same, here is the information:
It's indeed possible as below using just the "MEMS array microphone part of the UMA16".

power:
- no need to plug DC jack on UMA-16
- connect 3.3V and GND that power from MCHStreamer to UMA-16

PDM clock:
- connect PDM_CLK1(J3-16) of UMA-16 to PDM_CLK1(J3-11) of MCHStreamer
- PDM_CLK2 is nc

PDM data:
- connect PDM data0~7

Hoping this info helps and feel free to contact us if you have further questions.
