GPIO Scheme Raspberry Pi

A big feature of the Raspberry Pi is the row of GPIO (general purpose input/output) pins. These pins are a physical interface between the Pi and the outside world.

Raspberry PI model B+/2B/3B/ZERO has 40Pins:

  • 2x 3.3V
  • 2x 5V
  • 8x GND
  • 26x GPIO
  • 1x ID_SD
  • 1x ID_SC
WARNING: GPIO pins use a 3V3 logic level and are not tolerant of 5V levels.
If you short 5 V to any other pin you may permanently damage your Raspberry PI
