Pimoroni PIM435 5x5 RGB Matrix Breakout

This super-cute 5x5 RGB LED matrix breakout is a neat way to visualise sensor data or for simple animations or notifications, and it's Raspberry Pi and Arduino-compatible. These little matrices are ideal for visualising data like graphing environmental data from BMP280 or BME680 breakouts. Like many other breakouts, this one just pops straight onto your Pi's pins once you've soldered on the included right-angle female header, and there is an included trace that can be cut to change the I2C address from 0x74 to 0x77, if you want to use two matrices at once 5x5 (25 total) RGB LEDs Uses the IS31FL3731 driver chip15x15mm active area3.5mm LED pitchI2C interface (address 0x74/0x77 (cut trace))3.3V or 5V compatible Reverse polarity protection Compatible with all models of Raspberry Pi, and Arduino Python library Kit includes5x5 RGB Matrix Breakout1x5 male header1x5 female right-angle header They've designed this breakout board so that you can solder on the piece of the 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).
