A case for microcontrollers
Cases can be expensive for micro-controllers, but if you can forgo the exactness you can use very inexpensive containers, This is especially true for controllers that might have several layers or capes, and or add-on boards You can get inexpensive containers 3 or more for a dollar at a discount store. Once you have your containers, you will want to modify them. Then lastly you will want to bolt down the board. #4 machine screws should work fine for this. and viola you have your own case.
