Famicom cartridge dimensions
This page documents the dimensions of common Famicom cartridges, including their cartridge shell and their corresponding PCB type. The source files are open-source and available on Github.

Famicom cartridge PCB outline
HVC-TxROM
Cartridge PCB outline
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.
Card edge 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.
