- PCB Gerber Zip - Download
The hardware used for this project originally comes from instructables.com. This folder contains the PCB (printed circuit board) design that you will need to send off to a PCB printing/milling service. This has been printed with JLCPCB but any printing service should do as the board is relatively simple. For component assembly instructions, follow the instructables link.
Furthermore, the Stevenson screen enclosure can be 3D printed, however the design isn't well optimized and instead for this project we opted to use injection-molded junction boxes to house the PCB and solar panel.
