Bd845-pwb board
Bd845-pwb board is an open source STM32 PCB design by bluedot-arcade: a 4-layer, 185 × 110 mm board with 172 components (43 distinct parts). It is built around the C5947, C85364, C6186, C9865 and more.
A clone of the original Konami GN845-PWB(B) Stage I/O board for DDR machines.
The goal of the project is to replicate the original Konami GN845-PWB(B) Stage I/O board by designing a drop in replacement board for future-proofing DDR cabinets.
It emulates the original DDR Stage I/O communication protocol boot sequence allowing to run the game without an I/O Check Bypass. Other protocol features are currently not supported.
It also provides additional features such as debouncing and a Light-On-Press mode that lights up the arrow light when pressed without the need of an external lights driver board.
