The joystick module for hackxpansion!
The module uses a two-axis potentiometer joystick to provide X and Y analog readings, allowing projects to interpret directional movement and user input. The center button adds an extra digital input for selection or other interactions.

Pin Mapping
| Function | Xpanse GPIO |
|---|---|
| X axis | GPIO7 / ADC0 |
| Y axis | GPIO8 / ADC1 |
| Center button | GPIO9 |
See the Xpanse API docs
The joystick axes are connected as potentiometers between 3.3 V and GND, with their wipers connected to the ADC pins. This allows the X and Y positions to be read as analog voltage levels. The center button provides a digital input.

Questions
How big is the Joystick PCB?
It measures 32 × 25.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Joystick use?
8 parts, built around the RKJXV122400R. 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 arghya-v/hackxpansion-joystick repository on GitHub, at the commit this page was made from: the board is kicad/Joystick.kicad_pcb and its schematic kicad/Joystick.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 states no licence, so its author keeps all rights: ask arghya-v before reusing the design.
