ZK-PP1 PWM Signal Generator – 1Hz to 150kHz Square Wave, Dual Mode (PWM/PULSE), LCD Display, 3.3V–30V

📝 Product Description:

The ZK-PP1 PWM Signal Generator Module is a compact, high-precision square wave output module ideal for testing, development, and control projects. Featuring dual operating modes (PWM & PULSE), a 1Hz to 150kHz frequency range, and 0–100% duty cycle control, this module is perfect for MCU simulation, motor driver testing, LED dimming, and more.

The onboard LCD display clearly shows frequency, duty cycle, pulse width, and delay times in real time. With RS232 TTL serial communication, reverse polarity protection, and a push-button interface, the ZK-PP1 is simple to use and powerful in performance.
