EDID Emulator

The Design is finished, but the Hardware must be tested and programmed.

This Adapter is connected between a HDMI/DVI source and a Display replaces the EDID and Hotplug Detect of the Display.

Use cases:

• Keeping monitors connected to a PC while switching between different PCs with an inexpensive HDMI switch.
• Controlling the display settings when using an HDMI splitter.
• (Hopefully) use the HDMI Port of the TAng Nano 9k Dev board as a Input
• Create and save multiple EDIDs over Serial Interface
• Clone EDIDs of other Displays
• Inspect and read out EDIDs over Serial Interface

It has a USB-C Connector to access the Serial Interface, and two HDMI Ports for Input and Output.

The PCB is a 6-Layer PCB, so the TMDS lines have enough shielding.

It also provides a tiny formfactor with a PCB size of only 22,3mm x 33,7mm
