XMOS microphone boards or alternative?

Post by aclassifier »

XCORE.AI EVALUATION KIT (XK-EVK-XU316), HW description here has a connector for one or two PDM mics.

It connects to "XMOS microphone boards" - which I didn't find. Any URL?

However, if they haven't appeared yet, anyone out there who has used any commercial breakout boards?
Off Topic
Since one of my two mic array boards went dead here (and I haven't tried heating it in the oven, which my friend the expert suggested as a last resort. I fear it, bottom parts may fall off..) I need to port my SW onto the xCORE-200 dev board (which I have some of, here), and I am in need of a mic. I only need one. I have an overview (so far) at My MEMS microphones notes.

The Mic_clk and Mic_data are also available via headers, I guess just getting any old dual PDM module should work attached to these.

Thanks! That's really a good tip. I didn't think of it. Maybe I could then use that defect board as a mic board then, since the power is fine.

I have bought some, NW-AUD-ICS52000 board from notWired.co, see Using a PLL for mic clock(s) and will now use the XCORE-200 Explorer board with them. I guess I would'nt need the lib_mic_array now.
