DDMI (Differential Data Multiple Interface)

Overview

DDMI (Differential Data Multiple Interface) is a work-in-progress (non-)specification for differential data transfer over a 19-pin HDMI® style connector.

This repo contains the pinout for the DDMI connector and the DDMI Pmod™ compatible module.

DDMI Pmod

This project was inspired by DVI-PMOD, SmolDVI and the ULX3S GPDI connector.
