Product Features1. Wide voltage range of 3-24V, suitable for various devices2. Integrated start stop switch for more convenient operation3. Real time speed display, clear status at a glance4. Select high-quality materials with guaranteed quality5. Specially designed for optimizing standard servo signal protocolsProduct parametersDC 3-24V power supply3PIN power supply and PWM signal outputLED strength indicator speed percentageThe digital display shows the percentage of rotational speedWhen selecting servo/brushless ESC:PWM frequency fixed at 50HzThe speed regulation is adjusted to a positive pulse width range of 0.95-1.95msThere are three sets of solder joints on the back for configuring modes, as follows1. Default modeEmpty configuration, adjust speed with knob, buttons have no effect2. Power on startup modeShort circuiting the power on start configuration point, delaying the start by 3 seconds after power on to the speed set by the knob (simulating a human manually turning the knob from 0 to the set throttle)Suitable for scenarios where electric adjustment is required to turn the motor to a specified speed upon power on3. Switch start modeShort circuit switch start configuration point, does not start after power on, waits for the button or external switch to be pressed before starting. Note that it needs to be continuously pressed or the switch is short circuited to function. Release the button will slow downSuitable for scenarios that require external switches to control motor rotation/stopPacking ListMotherboard * 1188 digital tube * 13P bent needle * 110K potentiometer * 1Potentiometer cap * 1
