RPIO is an advanced GPIO module for the Raspberry Pi.

  • PWM via DMA (up to 1us resolution)
  • GPIO input and output (drop-in replacement for RPi.GPIO)
  • GPIO interrupts (callbacks when events occur on input gpios)
  • TCP socket interrupts (callbacks when tcp socket clients send data)
  • Command-line tools rpio and rpio-curses
  • Well documented, fast source code with minimal CPU usage
  • Open source (LGPLv3+)

The easiest way to install/update RPIO on a Raspberry Pi is with either easy_install or pip:

$ sudo apt-get install python-setuptools
$ sudo easy_install -U RPIO

After the installation you can use import RPIO as well as the command-line tools rpio and rpio-curses.

Debian packages are available at

An Arch Linux PKGBUILD is available at


You can find lots of examples inside the documentation, as well as in the /examples/ source directory.
