V0 OLED display pcb. It's simple" because there's no standalone electronics on it, you need to use the motherboard's outputs for all functions.
You need to do SMD soldering for the RGB LED on this PCB. If this is not a problem, or you don't want to use an LED, then choose this version. Otherwise, you can choose the other option with the assembled SMD components.
