ZK-PP1K PWM Signal Generator Module

The ZK-PP1K PWM Signal Generator produces adjustable rectangular signals for electronics testing and control projects. It offers two modes: PWM for a repeating waveform and Pulse for timed sequences. The onboard LCD lets you view settings directly on the module.

PWM Mode: Frequency and Duty Cycle Control

Set the PWM frequency from 1Hz to 150kHz and the duty cycle from 0% to 100%. Frequency sets how often the signal repeats, while duty cycle sets how much of each cycle the signal stays high. Use this mode to test a compatible PWM input or compare waveforms on an oscilloscope.

Pulse Mode: Delay, Pulse Width and Count

Set an output delay and adjust the high and low portions of the pulse separately. Choose a sequence of 1 to 9,999 pulses or let it repeat continuously. This mode is useful when you need a fixed number of test pulses or want to check how a circuit responds to a specific pulse length.

Supply Voltage and Signal Compatibility

The module runs on 3.3V–30V DC, and its signal amplitude follows the supply voltage. Check the receiving device’s input rating before connecting it. For example, powering the module at 12V can produce a signal near 12V, so use suitable level shifting before connecting it to a 3.3V input. To control a motor, connect the signal to a compatible motor driver.
