General Purpose Input Output (GPIO)

Resources:

eLinux.org RPi Low-level peripherals

Notes:

GPIO pins are 3.3 volt logic levels and are not tolerant of 5V levels
GPIO properties can be set as a block (GPIO pins 0-27 are in the same block) not per pin.
1. Can interrupt based on high/low/rise/fall/change.
2. Input hysteresis (Schmitt trigger) can be on or off,
3. Output slew rate can be fast or limited, and
4. Source and sink currents are configurable from 2 mA up to 16 mA.

The first 26 pins on J8 (A+ and B+ models) are the same as H1 on the A and B models.

H5 is only on the A and B models. GPIO 28-31 are not available on the + models. These signals should probably not be used.
