This monitor has a resolution of 480x272 and comes with a USB touch control board, making it easy to connect to the AM3359-SOM-EVB-IND via USB port.

How do you power the ESP32-POE? Is it powered from the same source as the LED strip? If not - did you measure if there is voltage difference between the two grounds? Can you give me a diagram or sketch or schematic on how the hardware connection and power supplies and grounds are connected?
