814 B

v1

this version comes as dongle, which can directly be plugged in the monitor. the impedance and length of the differential signal pairs are properly taken care of. a breakable tab replaces the WP switch. pads are still present to override the disabled WP and 5V.

the shield is not connected to ground, which causes EEPROM read errors with cheap HDMI cables skimping on the ground wire (pin 17). the workaround is to scratch the solder mask near one of the HDMI receptacle shell tab and solder it.

v0

first working version.

based on the design of the original research. the HDMI connectors are on opposite sides of the board to make the routing easy (the differential signals are straight lines). the impedance does not seem to by optimal, leading to EMF leakage (reported by the original researchers).
