Ahoy ye most based and redpilled Framework laptop (and others) users (read in a
|
|
pirate voice). This here repository contains the schematics for the first LTE
|
|
expansion card for the Framework laptop in the whole of the seven seas matey!!
|
|
|
|
Since we are a most merciful and generous crew, we are sharing the schematics
|
|
and assorted design files for the electrical and mechanical aspects of the
|
|
device with ye! Ye are free to modify and republish the design as ye wish under
|
|
the terms of our `CC BY SA 4.0` license, which requires that ye must provide
|
|
attribution for our design to our crew. To see more open the `LICENSE` file.

## 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](https://fcc.report/FCC-ID/2AAGEEG95NAX/5041436.pdf).
|
|
|
|
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.
