HGLRC 2812 LED Controller is a control board for programmable LEDs. The board has both a connector and solder pads. Therefore, any LED strip can be connected. The color of the individual LEDs can be easily changed by pressing a button or by using the PWM output from the control unit. The board can be powered by either 5V or 2-6S batteries. Mounting M3 holes with a spacing of 20 mm can be used to attach the board to the stack, or they can be easily broken off and the board can be attached in another way.
