Website
A handheld console with 4 expansion solts
Key Features
- Resistor based module identification at start up
- 2" 240x320 ST7789 LCD panel
- RP2354 MCU
- Easily adaptable module standard
- Rust firmware with embassy and slint-ui
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.
Main-Board
Daughter-Board
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 Joystick PCB?
It measures 25.5 × 32 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Joystick use?
6 parts, built around the COM-09032. 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 Joystick KiCad files?
From the hackclub/hackxpansion repository on GitHub, at the commit this page was made from: the board is hardware/modules/joystick/pcb/joystick.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 Joystick 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).
