## Description

Get retro with this 5x7 LED micro dot matrix - Also [available in Green](https://core-electronics.com.au/pimoroni-led-dot-matrix-breakout-green.html)

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 the fancy [Breakout Garden](https://core-electronics.com.au/pimoroni-breakout-garden-hat-i2c-spi.html), which makes it easy to use several different breakouts at the same time.

**Features**

- IS31FL3730 LED matrix driver chip
- 2x LTP-305 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](https://github.com/pimoroni/ltp305-python)

**Kit includes**

- Microdot Breakout
- 1x5 straight male header
- 1x5 right angle female header

Pimoroni has 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**
Pimoroni has put together a [Python library](https://github.com/pimoroni/ltp305-python) 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)
