I am lucky, the screen backlight is not damaged by my mistake. 😂
The LCD backlight power consume is 5V 100mA, 0.5w, pretty much. I think that’s why the media always says the screen is one of the most power-hungry components in the phone. 😅
Next part, let’s hack SPI and check if we can display anything to it.
PS: many people(include me) find white VoCore2 is hard to clean and go ugly after solder wires, so if no special request, we will ship green pcb version at vocore.io/store(also we still product white pcb version).
