We are using Raspberry Pi Model B: We used USB connector from PC - confirmed output - 5V, with 2 leads: Connected +5V to Pin 2 Connected GND to Pin 6 on connector -
Inserted Ethernet cable connected to the HUB/Router. We see the following LEDs: PWR - Solid RED ACT - Slow Blink GREEN TDX, LNK, 100 - OFF
Question: Do we need to power other GPIO pins as well example 3v3 or the other 5V (pin 4) to power the PRi? Or what are the pins we need to power to power the RPi?
