From the project

PHL GameBox Uzebox fork repo

Welcome to the official hardware design repository for the PHL GameBox, a factory-manufactured, feature-packed fork of the retro UzeBox 8-bit game console.

This repository contains all the KiCad schematics, PCB layouts, libraries, and manufacturing files needed to explore, modify, or manufacture the PHL GameBox hardware.

The PHL GameBox upgrades the traditional ATmega644-based UzeBox architecture with an integrated SMD-based component layout and expanded connectivity:

GameBox: common questions

What microcontroller does the GameBox use?

The GameBox is built around the RP2040, from the RP2040/RP2350 family.

How big is the GameBox PCB?

The GameBox measures 100 × 81 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the GameBox?

128 components, from 48 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 GameBox design files?

From the PHOL-LABS/GameBox 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 GameBox design in my own project?

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

Can I test firmware for the GameBox without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
