Summary

This is just a simple design for a case to hold a LM2596 Dc-DC step down conmverter, a Wemos D1 Mini, 5mm plug, and a logic level shifter. This is intended to provide an easy means to put these things together in one case to make it easier to use 12v LED's with the 5v Wemos.

The LM2596 is NOT encased in the enclosure, since it can get warm when in use. All components are attached to the case with hot glue to make them solid, easy to repair, and to make allowances for slight size deviations based on component manuifacturer.

I am using a Wemos D1 Mini Pro, so there is a hole on the upper corner for the external antenna wire- you can cover that up or just ignore it.

SKP file incliuded for customization.
