AJMRTC TLC5947 24-channel PWM LED driver breakout board adopts TI TLC5947 chip, providing 24 constant-current sink outputs for precise LED brightness adjustment. Each channel supports 12-bit 4096-level grayscale PWM control, delivering smooth and delicate lighting effects. Thanks to the built-in internal oscillator, the module can work without an external clock source, simplifying wiring design. The board accepts 3.0V to 5.5V logic power, which can directly connect with Arduino, Raspberry Pi and other common MCUs. Serial communication interface supports cascading multiple TLC5947 modules to expand LED quantity conveniently. Built-in thermal shutdown protection prevents damage under over-temperature condition. Ideal for LED matrix display, decorative lighting, stage light effect, embedded lighting control and maker electronic projects.
