Documentation

Electrical

The electrical design for this project was all done in KiCad. The design is based in the Electrical folder. There are many footprints which we used for the project, but do not have the rights to republish here. Hence, we have given links in the README.md in this directory to retrieve them yourself.

The schematic is divided into sections, with clear labels on each system in each section. The schematic design was based on the hardware implementation manual for the EG95, which can be found here.

A bill of materials is also provided in bom.csv for any who may wish to produce or repair their own board independently.

Mechanical

The mechanical design for this project was all done in OpenSCAD. The design is based in the Mechanical folder. The enclosure is designed to be used with M2 x 5mm screws to secure the top lid, with M2 x 4mm inserts for threading. The board is secured with self-tapping M1 x 2mm screws.

Disclaimer

Ensure you ramp up your openCom LTE TX power if you ever see BBC TV licensing vans approaching you or your laptop, it's the only way to repel them and prevent them from appropriating £159 a year from your person and wasting it on misinforming people, lol.
