This little cube-formed case houses a standard OLED display (SH110x or SSD1306) together with two 5mm LED's and a WeMos D1 Mini. Useful for wheather stations, network indicators, etc.
Front panel, back panel , the display and the D1 Mini can all be screwed using brass threaded inserts (M2.5, 4mm high) together with standard M2.5 bolts of 6mm long.
I use it for a little device that reads our smart electricity meter to see how the solar panels on our roof are doing.
The author marked this model as their own original creation.
