A tiny, tightly-packed matrix of 77 individually-controllable bright white LEDs. Ideal for scrolling text, animations, bar graphs, or just general illumination, and it's Raspberry Pi and Arduino-compatible.

This tiny, white LED matrix has 77 pixels packed onto a board that's the same size as a postage stamp! Each LED's brightness can be controlled individually, meaning that you can display all sorts of cool text, animations, and more on it. Why not use it as a controllable light source for your Raspberry Pi Camera?

Like Pimoroni other breakouts, this one just pops straight onto your Pi's pins once you've soldered on the included right-angle female header, and we included a trace that can be cut to change the I2C address from 0x75 to 0x77, if you want to use two matrices at once!

Features

• 11x7 (77 total) bright white LEDs
• Uses the IS31FL3731 driver chip
•  22x14mm active area
• 2mm LED pitch
• I2C interface (address 0x75/0x77 (cut trace))
• 3.3V or 5V compatible
• Reverse polarity protection
• Compatible with all models of Raspberry Pi, and Arduino
• Python library

Kit includes

• 11x7 LED Matrix Breakout
• 1x5 male header
• 1x5 female right-angle header

We've designed this breakout board so that you can solder on the piece of right-angle female header and pop it straight onto the bottom left 5 pins on your Raspberry Pi's GPIO header (pins 1, 3, 5, 7, 9).

Software

We've put together a Python library to make it really easy to drive the 11x7 LED Matrix Breakout, along with a handful of examples to show what it can do. 

Our software does not support Raspbian Wheezy.

Notes

Dimensions: 23x25x3mm.
