Gameboy: common questions

What microcontroller does the Gameboy use?

The Gameboy is built around the MCU-005, from the STM32 family.

How big is the Gameboy PCB?

The Gameboy measures 200 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gameboy?

125 components, from 53 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 Gameboy design files?

From the Nalydmerc/gameboy repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Gameboy design in my own project?

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

Can I test firmware for the Gameboy without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
