PSPi 6 turns the PSP 1000 into a Raspberry Pi handheld with open hardware designs

A hobbyist project that reached the Hacker News front page, PSPi 6, replaces the original mainboard of a PlayStation Portable 1000 with a custom circuit board that runs a Raspberry Pi, converting the classic 2000s handheld into a modern portable computer.

According to the project's GitHub repository, PSPi 6 is a personal project by the developer behind othermod. The repository publishes the hardware designs, firmware and software needed to build and use the device. The board's development is described as complete, with boards shipping and minor revisions still possible.

What the board does

Once installed, a Raspberry Pi becomes the handheld's brain. The repository lists three main use cases: playing retro games and emulators, running full Linux distributions as a portable computer, and using most software that works on a Raspberry Pi.

The conversion preserves the PSP's physical character. The board drives an 800x480 LCD with adjustable brightness, plays audio through the original PSP speakers or headphones, and wires up all of the original buttons and joystick. Volume and mute are handled with the PSP's own buttons, and the board supports two extra buttons and an additional joystick. LED indicators and an on-screen display report system status.

Power management is more sophisticated than a typical hobbyist build, with efficient charging, real-time battery monitoring and power-saving modes. One limitation noted in the repository: the Pi Zero and CM4 Carrier configurations produce mono audio, while a planned Universal Carrier is intended to add stereo output.

Compatibility

The project works exclusively with the PSP 1000 series; later PSP revisions are not supported.

On the compute side, the board accommodates the Raspberry Pi Zero, Zero 2 W, and the CM4 when paired with a CM4 Carrier board. It is electrically compatible with all 40-pin Raspberry Pis, but only the Zero and Zero 2 form factors physically fit inside the PSP shell.

The software options are broad. Supported operating systems include RetroPie, Lakka, Ubuntu, Raspberry Pi OS, Batocera and Kali, among others. The project maintains wiki pages covering required components, board installation, operating system setup and troubleshooting, with video tutorials available and a full assembly guide in progress.

Open hardware and how to get one

The hardware design is published under a Creative Commons (CC BY-SA) license, meaning anyone can share and adapt the design as long as credit is given. That opens two paths to ownership: buy a ready-made board from othermod.com for a closer-to-plug-and-play experience, or download the PCB design files from the repository, send them to a PCB manufacturer of your choice, and source and assemble the components yourself. The developer notes using JLCPCB for every board sold, but cautions that the self-build route requires advanced electronics and soldering skills.

The developer describes PSPi 6 as primarily a personal effort but welcomes community contributions, including bug reports, feature suggestions and documentation improvements. A Discord server hosts support and build-sharing, YouTube carries tutorials and updates, and the project accepts donations via PayPal and Patreon.

Why it matters

PSPi 6 sits at the intersection of two trends: right-to-repair-style hardware revival and open-source hardware reaching shipping products. Rather than letting aging consoles become e-waste, the project reuses the PSP's shell, controls and ergonomics, swapping only the electronics inside. Publishing the board files under a permissive license means the design can be independently manufactured, modified or forked by anyone, long after a commercial product would have been discontinued.

It also demonstrates how accessible custom hardware has become: a single developer can design a carrier board, have it manufactured cheaply, document it publicly and sell it worldwide. For retro gaming and Linux enthusiasts, the appeal is straightforward — a pocketable device that runs emulators and full desktop distributions while keeping one of the most recognizable handheld designs intact.
