It is written in the product information table that it can be powered by a 9V/12V USB PD charger, and a single 5V charger is not supported. However, due to project integration reasons, it is necessary to use a way to power the Raspberry Pi from the 5V GPIO like the Raspberry Pi. Does Rock Pi 4 support 5V power supply via GPIO? If so, what is the maximum current?
Does Rock Pi 4 support power supply via GPIO?
