PiBoy Advance: What It Is and What You Need to Build One

PiBoy Advance is a DIY Game Boy-style handheld built around an original RP2040 Pico, an ILI9225 display and custom electronics—not a confirmed retail console.

PiBoy Advance is a DIY Game Boy Advance-style handheld project by Arnov Sharma, not a standardized, ready-made retail console. It puts a custom Raspberry Pi Pico-based circuit in a modified GBA-style shell and runs Game Boy ROMs from an SD card. The documented build uses the original RP2040 Raspberry Pi Pico, an ILI9225 display and a MAX98357 I2S audio module.

What is PiBoy Advance?

PiBoy Advance is a maker project that combines custom electronics with a modified handheld shell. The project instructions describe a Pico running Game Boy ROMs from an SD card, with a small display, speaker and physical buttons. It is one documented build design, not a family of confirmed PiBoy Advance models or evidence of a complete retail product. Arnov Sharma’s project instructions were published on 20 September 2025.

What parts does the documented build use?

Part Documented setup What to check
Microcontroller board Original Raspberry Pi Pico with RP2040 The author reports that the selected software worked with the original Pico, but not Pico 2 or Pico W. Do not treat those variants as drop-in replacements.
Display ILI9225 display module Confirm the module’s board layout, interface and physical dimensions against the project wiring before buying.
Audio MAX98357 I2S amplifier module and a small speaker The project used a 1 W speaker, including an example reclaimed from another device; no specific speaker brand is established as necessary.
Power Single-cell 3.7 V, 1000 mAh LiPo with a power-management circuit This is the author’s example configuration, not a universal battery requirement. Cell dimensions and circuit layout affect fit and runtime.
Enclosure Modified Game Boy Advance-style shell The project does not establish current shell supply or universal fit with third-party replacement shells.

The build also requires a custom PCB and physical assembly. Sharma describes surface-mount work using solder paste, ESD-safe tweezers and a reflow hotplate, followed by fitting the electronics and buttons into the shell. The cited build does not document a simpler preassembled-board route, so builders should not assume one is available.

Which Pico board should you choose?

For the software setup documented by Sharma, choose the original Raspberry Pi Pico with the RP2040. The author reports trying Pico 2 and Pico W but says the chosen software worked only with the original Pico. That is project-specific compatibility guidance, not a general claim about what those boards can do with other software.

Can you print the enclosure?

Yes. Pinshape’s PiBoy Advance listing includes printable STL files for the shell, buttons and other parts, and identifies the files as downloadable under CC BY-SA. The listing establishes a printable-file option; it does not establish that a complete electronics kit is for sale. Check the model details and compare dimensions with your selected components before printing or buying other parts.

How long does its battery last?

Sharma reports 2.5 to 3 hours of gameplay from his build with a 1000 mAh, 3.7 V LiPo. This is the builder’s result, not an independent test or a guarantee for another unit. Battery choice, power-management implementation and the particular components can affect what a separate build achieves.

Is PiBoy Advance available as a kit or finished console?

The cited project and model pages describe a DIY build and printable enclosure files; they do not establish current availability of a complete kit, finished unit, original GBA shell or every electronic module. Treat the project as a build to source and assemble yourself, and verify component and shell availability before committing to it.

What to know before starting

  • Use the original RP2040 Pico for the documented software configuration.
  • Check display wiring, interface and dimensions against the project before ordering an ILI9225 module.
  • Plan for custom PCB assembly and reflow equipment if following the documented surface-mount route.
  • Confirm the chosen battery and power circuit fit the shell; the published runtime is specific to the author’s build.
  • Choose either a modified GBA-style shell or the printable project files, and verify fit rather than assuming every shell or replacement part is interchangeable.
