Is it possible to supply power to Raspberry Pi 4 using gnd on pin 9?
I need to power the Raspberry Pi 4 using GPIO pins. In most cases, people do this using 2 or 4 pins for 5V and 6 pins for GND. But the 6th pin is already occupied for cooling, and it is difficult to replace it, because the connector is dual with a voltage of 5 V.
