64x32 1/8 Issue

How are you powering the panel? You shouldn’t be powering from USB. That part looks like a diode which is meant to prevent external power from flowing to the computer. You likely can still run your ESP32 from external power if your shield supports it. You should contact the person that designed your hardware for support

I am powering it from external power supply connected to the esp32’s micro usb.

I will contact the designer of the shield.

Louis, thank you so much!

I didn’t test it time enough but i lowered the brightness to 15% and so far so good!
