Pico Fighting Board

Open source PCB for arcade sticks using Raspberry Pi Pico.

Introduction

They say imitation is the highest form of flattery. If that's the case then the Brook line of arcade controller boards must be blushing beet red. The Pico Fighting Board uses the same form factor and layout of the Brook PCBs to maintain compatibility with existing arcade stick cases, wiring harnesses, wire management accessories, etc.

The files for PCB production are in the Releases section. The zip file contains the Gerber and drill files, which is all you'll need if you're soldering SMT components yourself. There are also csv files for the BOM (Bill of Materials) and component positioning for SMT assembly service.

Firmware

The GP2040 gamepad firmware for Pi Pico/RP2040 has a pre-configured build for use with the Pico Fighting Board, providing support for XInput (PC, Android, Raspberry Pi, etc.), DInput (PC/PS3) and Nintendo Switch. Go to the releases and download the GP2040-PicoFightingBoard.uf2. To flash:

1. Unplug your Pico Fighting Board.
2. Hold the BOOTSEL button on the Pico and plug into your computer. A new removable drive named RPI-RP2 should appear in your file explorer.
3. Drag and drop the GP2040-PicoFightingBoard.uf2 file into the removable drive. This will flash the board.
4. The board should now be running the GP2040 firmware and should appear as a controller on your computer.

Modification

If you want to modify the PCB layout you'll need the free KiCad software installed. KiCad 5.1.9 was used for these instructions.
