Grove-Chainable RGB LED (Linkable LED lights)

Grove-Chainable RGB LED uses 2-wire transmission (data and clock) to communicate with the MCU. This 2-wire transmission can be used to cascade multiple modules. Built-in clock regeneration can extend the transmission distance. The Grove module is suitable for any project based on colored LEDs.


Item Value
Working voltage 5V

Communication protocol serial communication


  • Import the RGB_LED class in the routine warehouse and create an RGB_LED object
from RGB_LED import RGB_LED
led = RGB_LED(clk_pin, data_pin, led_num, clk_gpiohs_num, data_gpiohs_num, True)
  • Set the color of a light, the color value is rgb format
for i in range(led_num):
    led.set_RGB(i, r, g, b)
