M12 Lense suggestions for ESP32CAM microscope?

Hi guys,

I'm thinking about making a microscope of one of my esp32Cams to be able to get images of electronical platines.
I struggle to find a fitting m12 lense for that purpose, all I find seem to be wideangle and for surveillance cameras, not for doing macro stuff.

Thus, may you guide me here on which lense to buy?
