Konrad Beckmann’s Raspberry Pi Pico project taps the Nintendo 64’s digital video and sends DVI-compatible video through an HDMI-shaped connector. Beckmann reported that his prototype converted an internal 320×240 RGB565 image to 640×480 at 60 Hz. It is a DIY project—not evidence of a finished, currently available retail adapter—and the HDMI connector does not mean the output supports the full HDMI feature set.
What the Pico-powered N64 adapter does
The PicoDVI-N64 project is designed to provide digital video and audio output from a Nintendo 64 using a Raspberry Pi Pico and a DVISock. Rather than simply converting the console’s analog video output, Beckmann’s prototype taps its raw digital video signal and generates DVI-D signaling.
Beckmann described the reported mode as “320×240@RGB565 internally” and “a 640×480@60Hz signal” at the output in Hackster’s project report. Those are maker-reported prototype specifications, not independent test results or a guarantee that every display will accept the signal.
Why it is called HDMI output, but is DVI-compatible
The project sends DVI-compatible video through an HDMI-shaped port and cable. The connector’s shape can make “HDMI output” a convenient shorthand, but it does not establish support for the broader HDMI feature set, such as content protection or networking. The Adafruit PicoDVI guide explains the distinction between the connector and the signaling.

- The Raspberry Pi Pico is a beginner-friendly microcontroller board that uses MicroPython to give you a taste of the Internet of Things and microcontrollers. The RP2040 is a well-designed microprocessor that can be utilized in almost any Internet of Things project. It has enough power to complete the task quickly.
- 【Raspberry Pi RP2040 Microcontroller】Raspberry Pi Pico features Dual-core ARM Cortex M0+ processor, flexible clock running up to 133 MHz. With 264KB of SRAM, and 2MB of on-board Flash memory.Supports up to 16 MB of off chip flash memory via a dedicated QSPI bus
- 【Multiple Software Support】Pico has rich and complete software support, it comes with a complete Rasberry Pi official C/C++ SDK, Micropython SDK.The programming and burning of Pico need to be carried out on the computer. Supported operating systems and computers include:Raspberry Pie with Raspberry Pi OS,Other platforms equipped with Debian based Linux system Computer with MacOS, Computers with Windows, etc.
- 【Rich Hardware Interface】Raspberry Pi Pico has 30 GPIO pins, 4 pins for analog signal input and 26 × multi-function GPIO pins, 2 × SPI, 2 × I2C, 2 × UART, 3 × 12-bit ADC, 16 × controllable PWM channels.USB 1.1 supported by host and device, The installation mode can be flexibly selected by users to facilitate welding with other development boards.
- 【Build Project in Tiny Size】Only 2.1cm*5.1cm ( as small as your thumb). Pico has been designed to use either soldered 0.1" pin-headers or can be used as a surface-mountable 'module'.
What you need to build it
The project README lists two required hardware items: a Raspberry Pi Pico and a DVISock. The Pico alone is not an HDMI adapter; the build also involves wiring the hardware as documented in the repository.
- Raspberry Pi Pico: the RP2040-based microcontroller used by the project.
- DVISock: the DVI-output hardware specified by the project.
- Wiring and assembly: follow the repository’s wiring information; this is a hands-on DIY build rather than a plug-in retail accessory.
The project publishes prebuilt UF2 firmware and instructions for building with the Pico SDK. Its available firmware options pair audio sample rates of 32,000, 44,100, 48,000, or 96,000 Hz with RGB555 or RGB565 color modes. The README identifies the default file as 96,000 Hz with RGB555 and notes that particular games or applications may work better with different configurations. These are firmware choices, not guarantees of improved compatibility or picture quality.

How the Pico generates the video signal
PicoDVI uses the RP2040’s programmable I/O (PIO) to bit-bang DVI signals. Raspberry Pi describes that technique in its overview of the Pico as a possible GPU. That platform-level explanation helps clarify how a small microcontroller can generate a digital video signal; it is not a performance test of Beckmann’s N64 setup.
Prototype status and the community PCB option
Hackster described Beckmann’s implementation as an early prototype using wires and an external Pico. At the time of that report, he said a more complete kit might appear but that details were unknown. The cited project information does not establish that a finished retail adapter is now available.

A separate community PicoDVI-N64 PCB project documents a board intended to connect to Beckmann’s project. It includes Gerber files, a bill of materials, and flex-cable connection options. Its author described fit changes and testing as ongoing and noted unresolved resistor questions, so it should be treated as a community DIY design—not a validated kit or a universally compatible installation.
Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Display compatibility to keep in mind
Even if the console and adapter produce a signal, a particular monitor still needs to sync to its timing. The Adafruit guide warns that some PicoDVI timing modes may not work on every monitor. The reported 640×480-at-60-Hz prototype mode therefore should not be read as proof of universal display compatibility.

- This breakout board is specially made for Raspberry Pi Pico, with additional pin headers, which are fully compatible with the board
- The product needs to be soldered by itself, and the pico can be inserted after successful welding
- The breakout board is gold-plated on both sides and holes are plated, and the material of the PCB board is excellent
- The breakout board is equipped with Raspberry Pi pico, which is convenient for users to develop and integrate flexibly
- Note: The package does not include Raspberry Pi pico. This product needs to be soldered and assembled by yourself
The guide mentions other RP2040 boards capable of PicoDVI, but that does not establish that they are electrically or mechanically compatible with this N64 project. For a build, use the hardware and wiring specified by the PicoDVI-N64 project rather than assuming another DVI-capable board is a drop-in replacement.
