ESP32 LoRa case

thingiverse

This is yet another ESP32 LoRa case! ESP32's are little computers with a few input/output pins. The "ESP32 LoRa" is one of these Micro Controller Units, combined on a printed circuit board with an OLED display, and a LoRa (long-range) transmitter/receiver. Imagine a little thermometer in your greenhouse - the display on it shows the current humidity, and temperature, and the antenna transmits the information up to a few miles away - for example to your PC in the home-office! That's what these ESP32 LoRa gizmos can do when you add a few extra components. This case doesn't come with space for extra components, but you can drill holes into the side (or edit the OpenSCAD script) to expose the input/output pins to wire them up. The model of ESP32 LoRa I have has a power plug pointing AWAY from the circuit board - very awkward. I cut a hole in the back to plug in Li-ion batteries... It doesn't need screws as the base presses onto the front panel. The fit maybe too tight, so the square pillars on the corners of the base may need their sides filing down just a tiny bit.
