This is made possible by the PicoDVI library, which uses the RP2040's PIO state machines and one entire ARM core to bit-bang TMDS-encoded digital video without a dedicated display IC. The board generates a 320×240 or 400×240 pixel framebuffer that it pixel-doubles to 640×480 or 800×480 for output, compatible with any DVI or HDMI monitor (note: no audio is transmitted). Eight GPIO pins are dedicated to the DVI data signals. The DVI connector also exposes I2C through its DDC lines (level-shifted) as well as Hot Plug Detect, CEC, and utility pads for extended display communication. The rest of the board follows the standard Adafruit Feather specification: 8 MB SPI flash, 264 KB SRAM (up to ~150 KB available for user code after DVI buffers), USB Type-C for programming and power, 200 mA LiPo charger, onboard NeoPixel RGB LED, four mounting holes, and a STEMMA QT I2C connector. It is compatible with CircuitPython 8.1+, Arduino via the PicoDVI fork, and the Pico SDK with PicoDVI library. Ideal for retro gaming consoles, media players, and display-driven projects. ## Where to Buy - [Adafruit](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F5710&ref=openhardware.directory&product=adafruit-feather-rp2040-dvi&source=md-export) — 14.95 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.adafruit.com%2Fproduct%2F5710&ref=openhardware.directory&product=adafruit-feather-rp2040-dvi&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2Fadafruit%2FPicoDVI&ref=openhardware.directory&product=adafruit-feather-rp2040-dvi&source=md-export) - [learn guide](https://openhardware.directory/r?to=https%3A%2F%2Flearn.adafruit.com%2Fadafruit-feather-rp2040-dvi&ref=openhardware.directory&product=adafruit-feather-rp2040-dvi&source=md-export) ## Tags `adafruit`, `feather`, `rp2040`, `dvi`, `hdmi`, `display`, `circuitpython`, `video` ## Images ![Adafruit Feather RP2040 with DVI Output](https://nbg1.your-objectstorage.com/openhardware-directory/entities/adafruit-feather-rp2040-dvi/ab8783e77dbd.jpg) ![Adafruit Feather RP2040 with DVI Output](https://nbg1.your-objectstorage.com/openhardware-directory/entities/adafruit-feather-rp2040-dvi/2b42bdb8e6e9.jpg) ![Adafruit Feather RP2040 with DVI Output](https://nbg1.your-objectstorage.com/openhardware-directory/entities/adafruit-feather-rp2040-dvi/74b1afb50f71.jpg) --- [View full device page](https://openhardware.directory/devices/adafruit-feather-rp2040-dvi)
