Built using KiCad and ordered from PCBWay.
The Expansion Pak (or EP) was an add-on for the Nintendo64 console that gave it 4MB of extra RAM. This allowed for better textures and increased performance on some games; whereas other games like Donkey Kong 64 and The Legend of Zelda: Majora's Mask require the EP to operate.
There's been a lot of work done by very smart people to document other components of the board in this way including the console's motherboard, controllers, and other adapters, but nothing for the EP. This project aimed to create a version that could utilize the available 2MB modules that can still be found online. While not super abundant, this opens the door to use those modules and add more stock of reliable EPs to the market, as well as provide a starting point should new research be done with different RAM modules
