@Olli Rinne We allready tested a prototype on the Audiomoth.

Hi Olli, That is exactly the point 😊 We are planning to test the first boards next week. The boards will be circular 10mm (same size as electret) and prepared for selectable 2 or 3 wire connection.

We are working on a plug and play compatible circuit with a Knowles SPU0410LR5H-QB, does anyone have interest in such a board?
