The controller uses the ATmega328P to interface with the SNES controller inputs and handle communication with external hardware over the I²C bus.
The KiCad project contains the circuit schematic and PCB design, providing a starting point for reviewing, modifying, and manufacturing the hardware. Requirements
KiCad — for viewing and editing the schematic and PCB
ATmega328P-compatible programming hardware — for flashing firmware, if applicableGetting Started
Clone this repository:
git clone <repository-url>
cd <repository-directory>
Open the .kicad_pro file in KiCad.
Review the schematic (.kicad_sch) to understand the circuit.
Open the PCB editor to inspect or modify the board layout.
Run the electrical rules check (ERC) and design rules check (DRC) before manufacturing.Manufacturing
Before ordering or assembling the PCB:
- Verify the schematic and PCB design.
- Check component footprints and pin assignments.
- Run ERC and DRC in KiCad.
- Generate Gerber files and drill files using KiCad's fabrication tools.
- Confirm the bill of materials (BOM) and component availability.Parts

Questions
How big is the Snes Ctr PCB?
It measures 120.5 × 59 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Snes Ctr use?
25 parts, built around the ATMEGA328-PU. 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 Ctr KiCad files?
From the f0gger/Snes-Ctr repository on GitHub, at the commit this page was made from: the board is Snes-Ctr.kicad_pcb and its schematic Snes-Ctr.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Snes Ctr design in my own project?
Its repository states no licence, so its author keeps all rights: ask f0gger before reusing the design.
