⚠️ This project is currently under development; the PCBs have not been tested and may require additional optimization.
Introduction
This project aims to create an open-source, modular, and easy-to-understand design for a Hit Box layout using the Raspberry Pi (RP2040) as the core. My goal is to make the project as accessible and customizable as possible, providing everyone with the flexibility to adapt the design to their specific needs.
Chip Compatibility
- GP2040 chip: Offers higher compatibility with PC, PS4, PS3, Switch, and Xbox.

Costs
The cost to build the fight-stick will depend on parts, shipping, and tools. Below is a breakdown:
- PCB (minimum order of 5) without shipping: $8. Shipping will vary by location and method.
- Parts for PCB assembly: $25 (hot swap sockets, keys, switches, Pro Micro, and IC Sockets).
- Tools: Varies widely, but a cost-effective approach is possible.
Part List
Micro Chips List
Below is a list of top-tier microcontrollers that I've found to be the best in the market. While more cost-effective alternatives are available from sites like Aliexpress (which I've personally tested and found satisfactory), the following options are slightly more expensive but come with a guarantee of proper functionality.
If you're using a different 12-pin microcontroller that you think should be included here, feel free to leave a comment!
To ensure affordability, I've listed essential parts and some alternatives:
- PCB | $8 (without shipping)
- (optional) Hot-swappable PCB socket | $3
- Keycaps | $5-$15 (depends on quality)
- Switch | $5-$50 (depends on the manufacturer and "quality" of the switch)
- Pro Micro | $4-$30 (ensure the chip is RP2040)
Recommended
- KESTER SOLDER | $35-$60 (quality soldering wire)
- PINECIL – Smart Mini Portable Soldering Iron (Version 2) | $25.99-$35.99
Code
Upon connecting the microcontroller to your computer, a new drive will appear.
- Drag the
nuke.hfile into this drive; the microcontroller will disconnect and then reconnect. - Drag the
OpenBlock.hfile into the drive. You'll hear a sound indicating that the drive has disconnected and reconnected.
To test your controller, visit the Gamepad Tester Website. For modifying the code or creating new code, go to the GP2040-CE website. There, you'll find all the resources you need to customize or create new code. If you have any questions, refer to our Discord channel — they're awesome!
Note
This project is an open-source initiative, designed for modularity and ease of understanding. Contributions and suggestions from the community are welcome, fostering collaboration and growth.
