What if your business card could do more than share contact information? A community creator has made an RP2040-powered business card capable of running the classic 1993 game, Doom, showing that even small microcontrollers can handle retro gaming.
The project uses a Raspberry Pi RP2040 microcontroller, known for its dual-core capabilities, along with:
- 8MB Flash Memory for the game and assets.
- Color TFT LCD display and basic sound output via MAX98357 Amplifier.
- sleek PCB design that integrates all components into a business card-sized form.
- Two Type-C Ports- One port is dedicated to powering the device, while the other is used for connecting external peripherals, offering more versatility and functionality.
The build is based on a custom Doom port for the RP2040, designed for memory efficiency and optimal display.
In the image above, you can see a clear demonstration of the user playing Doom directly on this business card-sized device.
It’s an excellent showcase of the RP2040’s ability to handle not only business tasks but also deliver an enjoyable retro gaming experience. Whether you’re into gaming or electronics, this RP2040 business card is worth checking out.
