HT16K33 LED Controller Module

Description

The HT16K33 LED controller module is an integrated circuit designed to efficiently drive LED displays, capable of controlling up to 128 individual LEDs through I2C communication while offering low power consumption and adjustable brightness levels.

It communicates through the I2C interface, reducing the workload on the microcontroller, and features built-in RAM for storing LED control data. Low power consumption makes it ideal for battery-powered devices, and its brightness control allows for adjustable LED intensity. Holtek’s 28-pin HT16K33 LED controller/driver chip is used in the module. The HT16K33 is a multi-functional device that can drive a variety of LED display applications such as dot matrix, 7-segment, and alpha number 14-segment displays. It also includes a keyboard scanner, which is accomplished by multiplexing the same pins for driving the display and scanning for key presses.

It is commonly used in applications like digital clocks, scrolling LED signs, wearable devices, IoT devices, and gaming consoles, providing a versatile and cost-effective solution for LED display control.
