Singtown who make the OpenMV camera have made a custom OpenFlexure Microscope
Not only have they used their own camera, they have their own electronics for the motors with a screen on the front and buttons for moving the stage!
They made a really nice video. It is great to hear them talk about why they chose OpenFlexure over modifying a traditional microscope.
SingTown have also contributed their changes to the optics module back to the project via GitLab
