Arcade machines rely on various connectors and interfaces to ensure smooth operation and connectivity. The most common types include:

1. JAMMA Connector: The standard for arcade cabinets, the JAMMA (Japan Amusement Machinery Manufacturers Association) connector simplifies wiring by integrating power, video, and audio signals into a single harness.

2. VGA Interface: Used for video output, VGA (Video Graphics Array) connects arcade PCBs to CRT or LCD monitors, providing high-quality display signals.

3. DB15 Connector: Often used for control panels, the DB15 (D-subminiature) connector links joysticks and buttons to the arcade PCB.

4. RCA Connectors: These are commonly used for audio output, connecting speakers or amplifiers to the arcade machine.

5. Power Connectors: Molex and ATX power connectors are frequently used to supply electricity to arcade PCBs and peripherals.

Understanding these connectors ensures proper arcade machine setup, maintenance, and troubleshooting for an optimal gaming experience.
