## Description

PWM driver with TLC5947 for precise control of dimmable LEDs and other loads under 30mA, offers 24 independent channels with 12-bit resolution for fluid lighting effects. Operates at 3-5.5V logic, Arduino 3.3V and 5V compatible, communicates serially and automatically maintains the PWM cycle with the programmed values, includes thermal protection for stable use.
PWM driver, CJMCU-5947, compatible with Arduino and other development boards, both 3.3V and 5V, suitable for LEDs, is designed to control by PWM precisely, on 12 bits, consumers below 30mA, such as Dimmable LEDs.
It has 24 individually adjustable channels and communicates through a serial port.
PWM control automatically loops with programmed grayscale (GS) data, making it easy to create complex lighting effects.
This module can be successfully used together with LEDs to create creative lighting effects
