The LM4970 is an IC that pulses LED's in time to music! Perfect for your car, a casemod, or anything else that needs to be bright and flashy. The board itself measures a tiny 0.42 x 0.62 inches in size, yet is capable of driving multiple LEDS.

The LM4970 takes in Left+Right, or Mono audio inputs, and has 3 current controlled PWM led drivers; no current limiting resistors needed! The LM4970 is configured via I2C - and initialization is required for any light output.

The board is compatible with SPF Triple Color LED bars, our SMD triple color LEDs, or any common anode LED setup. It is not compatible with SPF Triple Color Through-Hole LED.
