Konrad Beckmann’s Raspberry Pi Pico project gives a Nintendo 64 digital video and audio output using DVI-compatible signaling through an HDMI-shaped connector. It is a maker-built prototype, not a finished retail adapter: the published build requires a Raspberry Pi Pico, a DVISock output board and wiring. Beckmann reported that his prototype converted an internal 320×240 RGB565 image to a 640×480 signal at 60 Hz; that is his reported operating mode, not an independently tested guarantee for every display.
What the Pico-powered N64 adapter does
The PicoDVI-N64 project is a DIY route to digital video and audio output from an N64. Its README lists a Raspberry Pi Pico and DVISock as required hardware and provides wiring details, prebuilt firmware files and instructions for building the software.
In the prototype report, Hackster.io described Beckmann tapping the console’s raw digital video signal and generating DVI-D signaling through an HDMI port. The familiar phrase “HDMI output” describes the connector and the kind of cable a user may attach; it does not mean the project implements the full HDMI feature set.
Why “HDMI output” needs a qualification
An HDMI-shaped port can carry DVI-compatible video. The signal generated here is DVI-compatible, rather than an indication that the converter supports HDMI-specific features such as content protection or networking. Adafruit’s PicoDVI guide explains the signaling distinction.
#1 Best Overall
- 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'.
The output therefore addresses digital video connectivity; the connector alone does not establish support for every feature associated with HDMI equipment. Nor does the reported prototype mode establish that every television or monitor will sync. Adafruit notes that some PicoDVI timing modes may not work with every monitor.
What Beckmann reported about resolution
Hackster.io quoted Beckmann saying that the prototype “uses 320×240@RGB565 internally and outputs a 640×480@60Hz signal.” These are the maker’s specifications for his prototype, not results from an independent test or a promise that the same mode will work on all displays.

The reported figures describe different stages: 320×240 RGB565 is the internal image mode, while 640×480 at 60 Hz is the output signal. Beckmann characterized the build as an early prototype, saying, “I literally just got it to work” and that there was still room for optimization. The Hackster.io report does not establish a finished product or a retail release.
What you need to build it
- Raspberry Pi Pico: named as required hardware by the project README.
- DVISock: the DVI output board named by the project; a Pico by itself is not the complete adapter.
- Console wiring and assembly: follow the project’s wiring information. This is a hardware modification, not simply a matter of loading firmware onto an untouched console.
The project publishes prebuilt UF2 firmware and instructions to build with the Pico SDK. Its files cover combinations of audio sample rates—32,000, 44,100, 48,000 and 96,000 Hz—and RGB555 or RGB565 color modes. The README identifies the default file as 96,000 Hz with RGB555 and cautions that some applications or games may work better with particular configurations.

Firmware choices and display compatibility
The available firmware combinations are configuration options, not a claim that one setting is best for every game, setup or display. Start with the project’s stated default, then consult the README if a particular game or application behaves better with another listed combination. If a display does not sync, the published material does not guarantee that changing a firmware option will resolve the issue.
The underlying technique is possible because the RP2040’s programmable I/O (PIO) can bit-bang DVI signals. Raspberry Pi explains that approach in its overview of the Pico acting as a GPU. That article provides platform background; it is not an independent test of Beckmann’s N64 prototype.
Rank #4
- 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
Community PCB option: a DIY design, not a retail kit
A separate community project, PicoDVI-N64_PCB, documents a PCB intended to connect to Beckmann’s project. It includes Gerber files, a bill of materials and flex-cable connection options. Its author describes fit changes and testing as ongoing and notes unresolved resistor questions.
That PCB is a community DIY design, not evidence of a validated, universally compatible installation or a finished product for sale. Treat its flex-cable and fit details as design-specific rather than assuming generic parts will be plug-and-play.
