Adafruit PiCowbell DVI Output for Pico - HDMI Display Adapter

Ding dong! The Adafruit PiCowbell DVI Output for Pico is a compact breakout board that enables you to display images and graphics directly from a microcontroller to an HDMI monitor or television via DVI (no audio support).

This DVI output board is the same size and shape as a Raspberry Pi Pico and sockets underneath it for easy integration. Features include a mini HDMI connector, STEMMA QT / Qwiic I2C connector, reset button, and a slide switch for customizable functions.

Key Features:

• Mini HDMI connector for DVI output compatible with standard HDMI displays
• Right angle JST SH connector for I2C (STEMMA QT / Qwiic) providing 3V, GND, and I2C lines with level shifting
• Reset button for restarting your program
• Slide switch on GPIO #3 configurable for various purposes
• Pin breakout for HDMI utility, CEC, and HotPlug signals
• Gold-plated pads and duplicated hole pads for flexible soldering and configuration

In Arduino, Adafruit provides a fork of PicoDVI library supporting 320x240 or 400x240 16-bit pixel framebuffers that output 640x480 or 800x480 pixel-doubled video. This library is compatible with AdafruitGFX for easy graphics programming. CircuitPython also supports DVI output but requires significant memory.

Note: The DVI video generation uses one full core, both RP2040 PIOs, and 150K-190K of SRAM, so system resources are heavily utilized.

Technical Specifications:

• Dimensions: 52.5mm x 20.2mm x 4.9mm (2.1" x 0.8" x 0.2")
• Weight: 4.3 grams

Included: Assembled PCB and header (requires soldering headers yourself).

Multiple header and stacking options available for various applications and form factors.
