ESP32-S2 Handheld Retro Gaming Console (gameboyy)

An open-source, custom PCB design for an ESP32-S2-powered handheld retro gaming console, designed in KiCad.

Features an integrated power management circuit, onboard USB-C programming, SD card storage for game ROMs, full tactile controls, and a display setup optimized for a compact form factor.

📐 PCB Design & Layout Highlights

  • Form Factor Optimization: Updated from an initial T-shaped outline to a solid rectangular board profile for better structural rigidity and easier 3D-printed enclosure integration.
  • Dual-Layer Copper Routing: Fully manual 2-layer track layout using both top (F.Cu) and bottom (B.Cu) copper layers, backed by full Ground (GND) Copper Pours on both sides for signal integrity and noise reduction.
  • RF Antenna Keepout: Carefully configured the ESP32-S2 board placement with an unshielded antenna keepout zone to prevent Wi-Fi attenuation.
  • Compact Vertical Stacking: Utilizes header pin socket height clearance so the TFT display mounts directly over the microcontroller, dramatically saving horizontal board space.

Questions

How big is the Game console project 1 PCB?

It measures 157.5 × 68.3 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Game console project 1 use?

21 parts, built around the ESP32-S2-WROVER-I(4M). The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Game console project 1 KiCad files?

From the weakestcatguy/gameconsolepcb repository on GitHub, at the commit this page was made from: the board is game console project 1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the Game console project 1 design in my own project?

Its repository states no licence, so its author keeps all rights: ask weakestcatguy before reusing the design.
