Why?

I really like the idea of modules, and modular things, and making people work together, so I made this.

PCB

The console has two 4 layer PCBs designed in KiCAD, a main-board and a daughter-board, designed for JLC's basic process.

Making Your Own Modules

There are three simple steps to making your own module:

Design the module PCB in KiCAD
Design the module case in CAD
Write a driver for the module

There are detailed docs on the hackxpansion website

Case

The case is designed in Autodesk Fusion, there are .f3z files in the hardware directory.

The models have parameters that can be adjusted to fit your needs.

Shoutouts

Thank you so much for Simon who helped with the fanout of the RP, and also gave a ton of constructive feedback!!!!

Questions

How big is the Linux soc PCB?

It measures 25.5 × 32 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Linux soc use?

57 parts, built around the F1C100S, TMI7003C and DSK24L. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Linux soc KiCad files?

From the hackclub/hackxpansion repository on GitHub, at the commit this page was made from: the board is hardware/modules/linux_soc/pcb/linux_soc.kicad_pcb and its schematic hardware/hackxpansion/pcb/ADC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Linux soc design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
