01 / Project overview
OGX-Mini is a published controller-adapter firmware project that supports multiple RP2040 and RP2350 hardware arrangements. The supported-board list includes Waveshare RP2040-Zero. Its documentation describes controller compatibility, output modes and a configuration interface for mappings and deadzones.
02 / Materials & software
- Waveshare RP2040-Zero or another explicitly supported board
- USB host wiring or supported adapter PCB
- compatible controller
FROM THE ORIGINAL PROJECT
The original RP2040-Zero internal arrangement shows one supported wired hardware build.

03 / Compatibility & setup notes
Compatibility depends on both the input controller and the target platform. Some targets have additional requirements; this overview does not claim that every controller works with every console.
AI CONCEPT
A conceptual controller, adapter and output-device workflow. AI-generated illustration; not the original project, a wiring guide or a tested build.
04 / Build the project
- Select the hardware arrangement and firmware flavor that match the board.
- Follow the upstream USB-host wiring or adapter-board guide and inspect the connections before power-up.
- Connect a supported controller and test a basic supported output mode before changing mappings.
FROM THE ORIGINAL PROJECT
The original web interface preview shows how adapter settings are exposed to the user.

05 / Check the result
Test buttons, axes and neutral positions on a simple gamepad tester. Confirm that a saved mapping survives a restart before assembling the adapter case.
PineMux build note: Keep a record of the board revision, firmware version and first successful test. Follow the upstream guide for exact pins and commands.
