Zero-Delay PCBs are found just about everywhere these days, promising no-lag performance and a very economical price tag, often costing less than $12. They are widely used in retro MAME PC arcade cabinet builds and interact with Retropie or EmulationStation boxes powered by Raspberry Pi and Orange Pi variants. However, many lack features that are desirable in the PC fighting game scene, such as X-Input and SOCD (Simultaneous Opposite Cardinal Direction).
Taiwanese company Brook - designers of the popular family of Super Converters and one of the first manufacturers whose converters managed to gain tentative acceptance by EVO - introduce the Pi Zero, an inexpensive yet fully-featured input control PCB designed for retro arcade and FightStick builders.
Pi, Console and PC Compatibility at Just $25.
The Zero Pi Fighting Board PCB packs a lot into its small price, offering control over the following:
- Raspberry Pi and Orange Pi (via USB)
- Playstation 3 (via USB)
- Playstation 2 (via J15 connection)
- PSX/Playstation 1 (via J15 connection)
- PC (via USB, X-Input)
- Nintendo Switch
Connection Features and Notes
The Pi Zero retains many of the connectors and headers that are now part of the Universal Fighting Board. The inclusion of JST headers instead of pin headers allow you connect our 4-Pin L3/R3/Touchpad Button Harness to this model. As now common in the Brook family of PCB boards, you can utilize USB 2.0 B printer cables to connect to the board, such as the 18 Inch Male A-B USB 2.0 Cable which connects to a Neutrik NAUSB-W-B A/B USB Feed-Through, or the 10 Foot Male A-B USB 2.0 Cable.
Screw Terminals Included
The Zero Pi possesses a screw terminal header. This means you can attach separate signal and ground wires to the PCB.
For easier installs, you can also purchase our 20-Pin Joystick/Button Harness at 25% discount when bundled with the Zero Pi. This harness includes eight .110 terminal button connectors, plus 3 option button connectors with ground daisy chain, plus 5-pin JST connector for Sanwa and Seimitsu compatible joystick levers. This will attach to the 20 pin male header located towards the bottom left of the PCB.
HitBox Conversion Harness
Lately, many fighting game players have flocked to the alternative, all-button control found in a HitBox layout. You can purchase our 5-Pin HitBox Conversion Harness, which connects to the 5-pin female joystick connector on our 20-pin Joystick/Button Harness. This allows you to utilize the Zero Pi's built-in SOCD cleaning feature.
Using an American Style Buttons and Joystick?
If you intend to use the Zero Pi to build a retro-style arcade cabinet with long stem pushbuttons from Industrias Lorenzo or Suzo Happ, you may try our Female .187" to Male .110" Conversion Wire (set of 2) for each button. The male end of the red signal and black ground wire attaches to the .110 female terminal on each button connector.
Additionally, you can purchase our .187 to 5-pin Conversion Harness to attach a Suzo Happ Competition or IL Euro Joystick to the 20-pin harness' female 5-pin connector. The conversion harness attaches to the .187" terminal microswitches found on these levers.
