Please note:  These are the older 26-pin version of the PiGlow! They will work with newer Raspberry Pi, but will require an adapter cable such as

Get visual feedback from your Pi! 

The PiGlow is a small add on board for the Raspberry Pi that provides 18 individually controllable LEDs. You can use it for all sorts of things! And of course, it fits inside a Pibow! 

There are tons of things you can do with it:

• Mood lighting / ambiance
• Showing current system load
• Notify you of events like mentions in tweets or incoming e-mail
• Feedback the status of scripts/daemons running on your Pi
• Works great when VESA mounted to provide a cast against a wall
• ...and pretty much anything else you can think of!

This board uses the SN3218 8-bit 18-channel PWM chip to drive 18 surface mount LEDs. Communication is done via I2C over the GPIO header with a bus address of 0x54 (Python example code provided). Each LED can be set to a PWM value of between 0 and 255. Comes fully assembled and ready to rock.

• 18 LEDs (three each of red, orange, yellow, green, blue, and white)
• Great to provide feedback if you're running your Pi headless
• PWM (dimming) control for each channel
• Fully assembled (no soldering required)
• Python code to access and control lighting provided
