Famicom cartridge PCB outline
These outlines of different cartridge PCB types are based on the most space-filling variant, so that designers may choose to cut off unused portions that their designs may not need. Some outlines of cartridges with no maximally space filling PCB are thus modified to be such, with measurements being based on adjacent types made by the same producer.
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.
HVC-TxROM
This outline is based on measurements from a HVC-TGROM-01 cartridge, compatible with any cartridge shell that supports any HVC-AxROM / FxROM / PxROM / SxROM / TxROM/ PCB or similar/bigger. These measurements are measured with vernier calipers with 1/128 inch accuracy. Note that this outline also details where the soldermask ends for the card edge.
