Get retro with this pair of 5x7 LED micro dot matrices - available in green or red!

We've always loved these old school LTP305 LED matrices (first developed in the 1970s!) and we thought it was high time we made a breakout with them. You get two 5x7 displays (plus a decimal point) and an LED driver, mounted on a Breakout Garden compatible I2C breakout. This breakout is preassembled, so there's no need for tiny soldering (unless you want to attach the breakout to a header).

This breakout is perfect for readouts that involve two numbers or letters - like countdown timers, percentage readouts, or country codes. You can also use the LEDs for graphical displays - a tiny graphic equaliser perhaps, or creepy light up eyes for a very small pumpkin! Their weird science vibe makes them great for cosplay and wearable projects too.

You can attach this breakout to your Pi's GPIO directly or via a breadboard with the included headers, but it's also compatible with our fancy solderless Breakout Garden, which makes it easy to use several different breakouts at the same time.

Features

IS31FL3730 LED matrix driver chip
2x LTP-305 green or red LED matrices
2x M2.5 mounting holes
I2C interface (default address: 0x61)
3V to 5V compatible
Reverse polarity protection
Raspberry Pi-compatible pinout (pins 1, 3, 5, 7, 9)
Compatible with all models of Raspberry Pi.
Python library

Kit includes

Microdot Breakout
1x5 straight male header
1x5 right angle female 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 with examples showing you how to control these LED displays. One of the examples is eyes 👀

Notes

The default I2C address is 0x61. You can change this to 0x63 by cutting the trace on the back of the breakout. If you cut the trace and solder the bridge the address will be 0x62 - so it's possible to use up to three of these breakouts at the same time.
Dimensions: approx 32.1mm x 20.8mm x 9.1mm (LxWxH)

These little LEDs work well for my project - very bright, fast and easy to interface using I2C.

Looks beautiful, simple to use in Python or C++, works with Pi and Pico boards (with the breakout garden) or by using the headers with any other controller. It's a lovely wee thing.
