This repository contains a KiCad project for a NES-CN-ROM-256-05 cartridge pcb.

Original NES-CN-ROM-256-05 schematic is from N. Schenk's NES repo. The schematic was modified to include currently available parts and their associated footprints.

Nes cnrom: common questions

What microcontroller does the Nes cnrom use?

The Nes cnrom is built around the ATTINY13A-PU, from the AVR/Arduino family.

How big is the Nes cnrom PCB?

The Nes cnrom measures 99.7 × 63.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Nes cnrom?

10 components, from 8 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Nes cnrom design files?

From the emeargt/nes-cnrom repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Nes cnrom design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which emeargt chose for the repository.

Can I test firmware for the Nes cnrom without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
