In the Hd’s description, It mentions:
The board haves a 5V boost converter and 5V<->3.3V IO level shifters for the I2C interfaces and hot plug signals on the HDMI ports.
Does it have a boost converter for the TMDS channels and other HDMI signals? If not what is the idea for communicating with the other HDMI interfaces?
Upon looking a little further, it turns out I might be a donut, because apparently the TMDS channels can be 3.3V.
