What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
You can build an Arduino game console as either a portable handheld or a desktop arcade setup. The most concrete current reference design is a 3D-printed handheld powered by an Arduino UNO Q 4GB; a desktop alternative uses the UNO Q’s Debian Linux side to run RetroArch and output to an HDMI display. The right route depends on whether you prioritize portability or a larger screen and full-size controls.
What an Arduino game console is
“Arduino game console” describes a project category, not one universal product: Arduino’s hardware catalog spans more than 100 products, including boards, carriers, shields, kits and accessories. Your console is a combination of a computing board, display, controls, power and enclosure, with software chosen for the experience you want.
The current official reference build is Zalmotek’s Retro Game Console powered by the Arduino Q, published July 9, 2026. Arduino’s August 6, 2026 blog post describes the design as approachable and says it requires no soldering. That claim applies to this project’s documented construction, not to every Arduino console someone might design.
Parts for the documented handheld
The reference bill of materials is specific to a handheld build. Check the display connector, carrier and power hardware against the project instructions before buying; not every screen or battery module will fit or work with another design.

| Part | Role in the build |
|---|---|
| Arduino UNO Q 4GB | The console’s main computing board. |
| Arduino UNO Q Media Carrier | The carrier used with the board in this design. |
| Waveshare 8-DSI-TOUCH-A 8-inch DSI touch display | The handheld’s display and touch input. |
| Modulino Buttons | Physical button controls; the instructions note that two of the three modules need their I2C addresses changed before chaining. |
| Modulino Joystick | Directional control. |
| Waveshare UPS Module 3S and 18650 battery | Portable power hardware. |
| Adafruit mono enclosed speaker, 3 W, 4 Ω | Audio output. |
| USB-C 2-in-1 PD + data adapter | USB-C power/data connection specified by the project. |
The enclosure and custom buttons are 3D printed, with M3 threaded inserts used for assembly. Arduino’s blog describes the wiring as mostly premade cables and wires and says no soldering is required for this design.
Assemble and configure the handheld
Build the physical console
- Print the enclosure and button parts, and prepare the M3 threaded inserts as directed in the Project Hub instructions.
- Assemble the UNO Q, Media Carrier, display, power hardware, speaker and controls using the project’s wiring and mounting directions.
- Before chaining the three Modulino Button modules, renumber two of them: they initially share I2C address 0x3E. Follow the project instructions for the address change.
Set up the UNO Q software
- Install App Lab on a workstation, then connect the UNO Q over USB-C.
- Follow the project’s setup flow to set the device identity, password and Wi-Fi connection, and enable SSH.
- Use the display drivers provided for the current image, following the project’s steps for the 8-inch DSI touch display.
The Project Hub instructions estimate about half an hour for the software side after the hardware is assembled and App Lab is available. That is the project’s estimate, not a guaranteed end-to-end build time; printing, assembly and troubleshooting are separate.

Choose between a handheld and a desktop arcade build
Arduino also describes a desktop route using UNO Q’s Debian Linux side with RetroArch, video over HDMI and audio over USB. A controller can use Modulino nodes or other Arduino-compatible hardware. It suits a fixed setup with a larger screen and room for full-size controls.
| Decision point | Handheld reference build | Desktop arcade route |
|---|---|---|
| Form factor | Self-contained portable console. | Fixed desktop or arcade-style setup. |
| Display | 8-inch DSI touch display in the documented design. | HDMI display; screen size depends on the display you choose. |
| Power | UPS module and 18650 battery hardware are in the reference parts list. | Fixed power is the more natural arrangement; the blog does not specify a power supply. |
| Controls | Modulino Buttons and Joystick fitted into a compact printed enclosure. | Controller assembled from Modulino nodes or other Arduino-compatible hardware. |
| Fabrication | Requires a printed enclosure, custom printed buttons and assembly with threaded inserts. | The cited route does not prescribe a particular enclosure or fabrication method. |
| Software and output | App Lab-based setup, device configuration and display-driver steps documented by Project Hub. | Debian Linux with RetroArch, HDMI video and USB audio. |
Before choosing, check five practical constraints: whether you need portability, whether your chosen display matches the board’s connection, how complex a control layout you want, what fabrication you can do, and which software stack you are prepared to configure. For a handheld, also plan the battery installation and safe handling of the chosen battery hardware; the cited project identifies its power components but does not establish a runtime figure.

What the available documentation does not establish
The cited project and Arduino posts do not publish an independent performance benchmark, a supported game count or a battery-runtime measurement. They establish a build path and named components, not how many games will run well or how long the handheld will operate on a charge. Treat compatibility and performance as matters to verify for the particular software and games you intend to use.

If the printed handheld is a large first project, Arduino’s kits offer structured ways to learn relevant hardware skills, though they are not console kits. The Make Your UNO Kit includes components to build a classic UNO, a synthesiser shield and a 3D interactive soldering guide. The CTC GO! education kit describes classroom hardware for up to 24 students, including eight UNO WiFi Rev2 boards, shields, breadboards, batteries, cables, sensors and actuators. The Plug and Make Kit includes seven Modulino nodes, a Modulino Base, an UNO R4 WiFi and seven example projects; it can help you explore interactive controls before tackling a console enclosure.
