Famicom cartridge PCB outline

HVC-TxROM

This outline is based on measurements from a HVC-TGROM-01 cartridge, so it should be compatible with any cartridge shell that supports any HVC-AxROM/FxROM/PxROM/SxROM/TxROM/ PCB or similar/bigger. These measurements should approximate closely, as it assumes a 1/128 inch grid.

Famicom Cartridge pin dimensions

Each cartridge type varies in how the 60 pin card edge is implemented. The pin pitch is 2.54mm, with 2 rows of 30 pads. Each pad may be uniform in dimensions, or slightly thicker and longer for power/ground. This outline is based on measurements from a HVC-TGROM-01 cartridge, with bigger pads to accommodate power. Note that this outline also details where the soldermask ends for the card edge.
