After we got the breadboard prototype running it was time to choose an enclosure and design a PCB to get everything together. For the board we choose not getting bigger as 10x10cm to keep costs down.
We searched for a waterproof enclosure which should house booth the solar charging regulator and the pcb. This project box turned out as a perfect fit.
The PCB was designed to fit into the enclosure and hold most of the components from the breadboard. It was designed in KiCAD and ordered on smart-prototyping.
This was the first PCB designed by me, but it turned out very well.
Some pictures of the finished nodes in the boxes
Note that on the last 2 pictures the RPi box is on the lower right side. It’s basically the same PCB repurposed. Instead of a pluged in Arduino pro mini its connected through jumper wires to the GPIO.
