16x8 HT16K33 LED Driver - 128 LEDs Control via I2C

Driver for the 16x8 matrix (128 single LEDs) based on HT16K33 - a small chip. The I2C communication protocol only uses 2 pins and it is possible to use up to 8 selectable I2C addresses, so that's a total of 8 matrices, of which a total of 1024 LEDs can be controlled. The driver has a lot of pins and is an alternative to the microcontroller. Technical data Working voltage: 4.5V ~ 5.5V Integrated RC oscillator I2C-bus interface 16 * 8 bits of RAM for display data storage Max. 16 × 8 patterns, 16 and 8 commons segments R / W of auto increment address Max. Scanning element 13 x 3 matrix 16-step dimming system Choice of 20/24/28-pin SOP packet types Application Industrial control indicators Digital clocks, thermometers, counters, meters Combo sets VCR Kits Tool readings Other consumer uses LED displays
