Maximum 8A (capable of directly driving motors or LED strips). Pulse Count: Adjustable from 1 to 9999, or set to infinite ( 2. Dual Operating Modes You can switch between these two modes by long-pressing the button for 2 seconds. PWM Mode (Display shows "%") Used for continuous speed control or dimming. Frequency: Set the oscillation speed (e.g., 20KHz). Duty Cycle: Controls the "On" time vs. total period (e.g., 60%). Pulse Mode (No "%" on display) Used for precise control of motor steps or timed bursts. Positive Pulse Width ( Duration the signal is HIGH. Negative Pulse Width ( Duration the signal is LOW. Pulse Number: The exact number of pulses to send before stopping. Delay Start: Sets a timer before the pulse sequence begins. 3. Button Functions & Settings ON/OFF Button:

Dimming lights, controlling DC motor speeds, or testing ESCs. Mode 2: PULSE Mode (Display: No "%") This mode is for precise timing and triggered events. P+ (Positive Pulse Width): Time the signal stays High. P- (Negative Pulse Width): Time the signal stays Low. Zk-pp2k Manual
For factory or school environments, you can trigger a buzzer at specific times: Maximum 8A (capable of directly driving motors or
Whether you’re dimming high-power LEDs or controlling the speed of a DC motor, the is a powerhouse module. With a wide voltage range of 3.3V to 30V and a hefty PWM Mode (Display shows "%") Used for continuous
If you have just purchased this module and are staring at a blinking blue OLED screen with no idea how to set the current limit or calibrate the voltage, you have come to the right place. This manual covers everything from the initial wiring diagram to advanced calibration steps.
The device features two primary modes, which can be toggled by long-pressing the button for 2 seconds: PWM Mode : The screen displays "%" for duty cycle. Parameters : Frequency and Duty Cycle.
