New DC 5V 30Ma I2C 8x8 LED Matrix HT16K33 Lattice Module Black >>Description Product Description: What's better than a single LED Lots of LEDs! 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' - so 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. Here we feel your pain! 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. General: Form Color: Black. Quantity:1Set. Material:FR4. Specification: Working Voltage :DC 5V. Working Current:>/= 30Ma. English Manual / Spec :No. Other Features:The matrices use a driver chip that does all the heavy lifting for you: They have a built in clock so they multiplex the display. They use constant-current drivers for ultra-bright, consistent color, 1/16 step display dimming, all via a simple I2C interface. These 1.2" matrix backpacks come with three address-selection jumpers so you can connect up to eight 1.2" 8x8's together (or a combination, such as four 1.2" 8x8's and four 7-segments, etc) on a single I2C bus. Working voltage: DC 5V Working current: 30mA Working temperature: -10~50 IO Interface: IIC. Packing List 1 x I2C 8x8 LED Matrix HT16K33. >>Payment We only accept payment through Paypal.
