Cart: common questions

What microcontroller does the Cart use?

The Cart is built around the ATTINY13-P, from the AVR/Arduino family.

How big is the Cart PCB?

The Cart measures 100 × 61.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cart?

38 components, from 19 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 Cart design files?

From the digilogistist/The-Open-Source-USB-NES-Project repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Cart design in my own project?

Yes, under the terms of its CC0-1.0 license, which digilogistist chose for the repository.

Can I test firmware for the Cart 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.
