PiGlow is a spiral nebula of 18 coloured, individually-controllable LEDs for your Raspberry Pi.

This diminutive board is compatible with the Raspberry Pi 4, 3, 2, B+, A+, Zero, and Zero W, and can be controlled really simply with our PiGlow Python library.

Use PiGlow for mood lighting/ambience, monitoring the status of your system, scripts, or daemons, Twitter mentions or emails, VESA-mounted behind your monitor or TV, or a zillion other things!


  • 18 coloured LEDs (3x each red, orange, yellow, green, blue, white)
  • Driven by the SN3218 8-bit, 18-channel PWM LED driver
  • Uses I2C (address 0x54)
  • PiGlow pinout
  • Compatible with Raspberry Pi 3, 2, B+, A+, Zero, and Zero W
  • Python library
  • Comes fully assembled


Our PiGlow Python library makes controlling PiGlow a piece of cake. You can control the brightness of the different colour groups of LEDs, the arms of the nebula, or individual LEDs - flexible! There's also a handful of examples to show you what can be done.

Our software does not support Raspbian Wheezy.
