Adafruit PiCowBell HSTX DVI Output for Pico

The PiCowbell HSTX DVI Output for Pico makes connecting a microcontroller to an HDMI display simple and efficient. Designed to pair seamlessly with the Pico, it mirrors its size for an easy socket fit underneath.

Equip your projects with a mini HDMI connector for video output, and utilize the STEMMA QT/Qwiic for quick I2C connectivity. Features such as a reset button and a slide switch offer customizable functionality, enhancing user control.

The PiCowbell is distinguished by its slim slide-switch and USB host port pads, which allow you to integrate peripherals using PIO-USB. With optimal compatibility on Pico 2 models, leverage the HSTX peripheral for efficient video generation, saving on PIO and processor resources.

Technical specifications include GPIO pins for raw HDMI output, pin breakout for HDMI extras, including CEC and HotPlug pins, and solder-jumpering options with duplicate hole pads and clearly marked ground pads. The gold-plated pads ensure easy soldering, offering flexibility with Pico Stacking, Socket, or Short Socket Headers for various assembly configurations.

By utilizing the Adafruit DVI libraries, create sharp digital displays effortlessly from internal framebuffers, with support in CircuitPython. The HDMI I2C pins connect through a level shifter, enabling you to read display EDID EEPROMs. Additionally, receive real-time updates when displays connect via the Hot Plug Detect.
