This is a universal microcontroller adapter for my modular microcontroller and breadboard holder.

It should be able to hold almost any microcontroller out there. If you find one that doesn't fit, just let me know!

You can ether screw the microcontroller in or clamp it with the indents.

To assemble the holder, you will need 4x M3 10mm screws and 4x nuts. To hold the controller, you can either use the M2 version or the M3 version, depending on the holes in the controller. There are short and long arms, so you should be able to hold even the larger boards.
