The Grove – LED String Light module is essentially an LED driver for the LED string lights included in the pack. The voltage of the module is 3.3V/5V, however, the LED string lights require a working voltage of 12V. Therefore, this module uses an AIC1896 current mode step-up DC-DC converter to provide the requisite voltage to the LED string lights. The LED string light is 5 meters in length and has 50 RGB LEDs on it connected equidistant to one another. You can use these to dress a Christmas tree, light your party or decorate your room.
