MOS6581: common questions

What microcontroller does the MOS6581 use?

The MOS6581 is built around the ATMEGA2560-16AU, from the AVR/Arduino family.

How big is the MOS6581 PCB?

The MOS6581 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the MOS6581?

52 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the MOS6581 design files?

From the dandandrea/MOS6581-PCB repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the MOS6581 design in my own project?

The repository has no license, so all rights stay with dandandrea. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MOS6581 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.
