DPS5020 case

A case for the DPS5020 Power supply Module. It is designed so that you dont have to work precicely when removing the support. The screwholes for the lid are 2,5mm so M3 should work, however special plastic screws are better. For mounting the electronics from the bottom I recommend countersunk screws.

Besides the DPS5020 I used this step up-down module, mounted with the heatsink facing upwards:

I connected the fan to this step up-down converter and mounted it with superglue. The Hole for the fan has a diameter of 43mm. The cables for the DPS go over the heatsink of the converter.

Under the Bluetooth logo is a hole for a switch, which toggles between USB and Bluetooth connection. I connected the switch between the ground of the the USB/Bt module.

The holes for the banana terminals in the front and in the back have a diameter 7mm.
