2 Channel PWM Pulse Frequency Adjustable Duty Cycle Square Wave Rectangular Wave Signal Generator Module

Produces square wave signals with independently adjustable frequency and duty cycle on two channels, without a microcontroller involved. Useful for testing motor drivers, dimming LEDs, driving servos, generating clock signals and bench testing circuits that need a controllable pulse input. A practical diagnostic tool for anyone building motor or lighting systems, since it lets you isolate whether a fault is in the driver or the control signal. Two independent channels with separate settings; Adjustable frequency and duty cycle; No microcontroller or programming needed; Useful bench tool for testing drivers and dimmers
