KEYESTUDIO 3Pcs I2C Interface 8X8 LED Dot Matrix Display Module Kit for Arduino Raspberry Pi Project
Introduction A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display. Matrices like these are 'multiplexed' - to control 64 LEDs you need 16 pins. That's a lot of pins, and there are driver chips like the MAX7219 that can control a matrix for you, but there's a lot of wiring to set up and they take up a ton of space. After all, wouldn't it be awesome if you could control a matrix without tons of wiring? That's where these lovely LED matrix backpacks come in. The matrices use the constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface. Features This matrix is RED, BRIGHT, Great display and easy to use! 8 rows and 8 cols LED matrix driven by HT16K33 chip Access to I2C communication pins Occupy less IO ports of microcontrollers It is very nice to plug into a breadboard or connect with jumper wires. The software which drives them are easily downloaded and installed in the Arduino IDE. Truely a cool learning tool for kids and adults. Parameters Input voltage: 5V Rated input frequency: 400KHZ Input power: 2.5W Input current: 500mA Read more Get this for a project- bright display, easy to get working on the Arduino or even your own custom hardware! Connect the SCL pin to Analog pin A5, SDA pin to Analog pin A4; Connect VCC pin to 5V, GND pin to GND. It allows you to auto create the sequences to display a graphic with ease. Read more
