Raspberry Pi to JAMMA Adapter

Description

The Raspberry Pi to JAMMA  is an adapter that will allow your Raspberry Pi to connect to a JAMMA compatible arcade cabinet for an unbeatable multi-game emulation experience.

Features

Here’s a quick summary of the features of the PJ Raspberry Pi to JAMMA adapter.

• Inexpensive. See pricing information above.
• Works on all Pi devices with a 40 pin header (no Pi 1 A models unfortunately)
• Low latency control hardware – joystick and button status updates each frame.
• Straight, one step digital to analog, video and sound conversion for a clean picture and sound.
• Native video resolution – no scaling or shimmering artifacts with standard resolution games.
• Zero latency video – one step digital to analog conversion, no scaler buffering required. 
• Power monitoring and reporting.
• Auto shutdown on brownout (with a super capacitor bank) will not chew up your SD card. Just turn off your arcade machine and walk away.
• Images for major Retropie releases will be provided.
• Opensource drivers and configuration for more customization.
• Plugs into JAMMA with SF2 kick harness support.
• All IO done through GPIO header. Nice and clean with no messy wires.
• Old skool, through hole design with IC sockets for easy repair and troubleshooting.
