PWM Signal Generator Module — 1Hz–50kHz, Adjustable Duty Cycle, Arduino

PWM Signal Generator Module — 1Hz–50kHz, Adjustable Duty Cycle, Arduino

A compact PWM signal generator module producing adjustable PWM signals from 1Hz to 50kHz with 0–100% duty cycle control — all adjustable via onboard potentiometers. Generate PWM signals for motor speed control, LED dimming, servo testing, and PWM circuit development without writing any code. The module outputs a clean, stable PWM signal that can drive MOSFETs, motor drivers, and other PWM-controlled devices directly.

Key Specifications

• Frequency range: 1Hz–50kHz (adjustable via potentiometer)
• Duty cycle: 0–100% (adjustable via potentiometer)
• Output voltage: 0–5V PWM signal
• Supply: 5V DC
• Output current: up to 30mA (direct drive)
• Display: LED frequency indicator
• Compliance: RoHS compliant

Why a Dedicated PWM Generator?

• ✅ No code required — adjust frequency and duty cycle with potentiometers
• ✅ Wide frequency range — 1Hz to 50kHz covers most PWM applications
• ✅ Independent frequency and duty cycle — adjust each parameter separately
• ✅ Stable output — crystal-controlled for consistent PWM signal

Typical Applications

• DC motor speed control via MOSFET or motor driver
• LED brightness dimming control
• Servo motor testing and calibration
• PWM circuit development and testing
• Fan speed control
• Power supply switching frequency testing
