3-Channel LCD PWM Signal Generator — 1Hz–150kHz, Adjustable Duty Cycle, Square Wave

3-Channel LCD PWM Signal Generator — 1Hz–150kHz, Adjustable Duty Cycle

This 3-channel PWM signal generator module produces up to three independent square wave outputs with adjustable frequency (1Hz to 150kHz) and duty cycle (0–100%), displayed on an integrated LCD screen. Each channel can be set independently, making it useful for testing motor drivers, LED dimmers, servo controllers, and digital circuits that require a PWM input signal. Operating temperature -40°C to +80°C for lab and field use.

Specifications

• Channels: 3 independent PWM outputs
