CJMCU TLC5947 PWM LED Driver Module - 12-Bit, 24-Channel

The CJMCU TLC5947 PWM LED Driver Module is a 24-channel, constant-current sink LED driver module. It provides individual PWM control for each channel with 4096 steps. GS data are written through a serial interface, and the grayscale control repeats automatically. A single external resistor sets the current value for all 24 channels. The module also includes thermal shutdown protection that turns off all outputs during an over-temperature condition.
