Open Source Cartridge Reader

This project represents a community-driven effort to provide an easy to build and easy to modify cartridge dumper.
Happy making. 🔧🔨😊

For any questions or issues please also visit the accompanying thread in the Arduino Forum.
And be sure to check the guides in the Wiki too.

Features:
  • Completely stand-alone, does not need a PC to operate (unless for updating firmware)
  • Easy to modify open-source code, write your own extensions and share them with others
  • Portable thanks to a battery
  • Modular design using mostly off-the-shelf components

Questions

How big is the Snes adapter PCB?

It measures 96.6 × 25.5 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Snes adapter use?

8 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Snes adapter KiCad files?

From the dkidd928/cartreader repository on GitHub, at the commit this page was made from: the board is hardware/snes_adapter/snes_adapter.kicad_pcb and its schematic hardware/famicom_adapter/famicom_adapter.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Snes adapter design in my own project?

Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
