Adafruit 871 Mini 0.7" 8x8 LED Matrix With I2C Backpack Yellow

Product Description

Adafruit Mini 0.7& Prime; 8x 8 LED Matrices with I2C Backpack
- Adafruit 871, The Adafruit Yellow Mini 0.7" 8x 8 LED Matrices take the pain out of using matrix displays by including an I2C backpack to do the constant current driving & multiplexing. Connecting displays like this can be quite expensive in precious GPIO pins, but with the added backpack they only use the 2 x I2C signals plus 2 x power connections. They are great for microcontrollers with limited outputs such as the Adafruit Trinkets which only have 5 x IO pins. They're also handy for grown up boards like the Raspberry Pi which have better things to do with their time than multiplex LEDs. Applications such as electronic jewellery, animated signs & badges or VU meters suddenly become much simpler. Alternatively, we supply Adafruit 4-digit 7-segment displays which also have I2C backpacks, great for meters, clocks etc. Each board has address selection jumpers allowing you to have 4 x of these displays attached to a single I2C bus. There are I2C commands to write to a pixel & to adjust the brightness. As you would expect Adafruit have also published a free library & a tutorial to get you off to a quick start. Supplied with a 4-way strip of header pins for you to solder on as required for your project. Adafruit 871 Mini 0.7" 8x 8 LED Matrix with I2C Backpack Yellow
