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.

Hello,
The TMDS physical layer specifications defines that the signals are 3.3v, so these pairs don’t need voltage conversion

Yeah the I2C interface is at 5V, TMDS (video signals) run at 3.3V. It’s kind of like USB, 5V power, 3.3V signaling.

Good to know. I saw the I2C voltage and assumed that everything was at the level. I am very new to electrnics at a whole so I know vey little. Thanks.
