Input: 2-6S batteries (6-28V) Switch Control: Integrated BEC for light control, controlled via the C pad LED Control Channels: 4 channels Linkage Channels: 1 signal input (servo PWM signal), controlled via the L pad Supported LEDs: WS2812B and other full-color RGB LEDs Supported LED Quantity: Up to 60 LEDs per channel. For total power exceeding 10W, use a separate 5VBEC to power the light strip. Power Calculation: Per LED: R = 17mA, G = 17mA, B = 17mA. That is, for a single LED displaying red, green, or blue at maximum brightness, the current draw is 17mA. For white at maximum brightness, the current draw is 17 x 3 = 51mA. For a large number of LEDs ( 40), avoid constant white lighting, which can cause excessive overheating.
