Signal Generator Module 2 Way Pwm Pulse Frequency Duty Cycle Adjustable
The 2-channel PWM signal generator module is designed to produce square wave signals for experiments, development, and control applications. It supports dual independent PWM outputs and is suitable for driving stepper motor drivers, microcontroller circuits, and other systems requiring pulse width modulation (PWM).
Package Includes:
- 1 x Signal Generator Module 2-Way PWM Pulse Frequency Duty Cycle Adjustable
Features:
- Dual Channel PWM: Supports two independent channels (PWM1 & PWM2).
- Adjustable Pulse Frequency: Ranges: 1Hz–999Hz, 0.1kHz–99.9kHz, 1kHz–150kHz.
- Adjustable Duty Cycle: 1% to 100% configurable.
- Stepper Motor Driver Support: Provides suitable square waves to drive motors.
- MCU Integration: Outputs are suitable for MCU-based timing and control.
- Serial Port Control: Operates over 9600 bps with specific command format.
- 3-Button Interface: Includes Set, Up, and Down buttons for local adjustments.
- Feedback Display: Indicates success ("DOWN") or failure ("FALL") of settings.
- Easy Parameter Shifting: Cycle through PWM1/2 frequency and duty via keypad.
- User-Friendly: Simple interface for configuring and operating the module.
Principle of Work:
- Power Supply: Connect a power source (5–30V or 5V via micro USB).
- Serial Control: Communicate using 9600 bps, 8 data bits, 1 stop bit, no parity.
- Command Examples:
- "S1FXXXT": Set PWM1 frequency in Hz (001–999).
- "S1FXX.XT": Set PWM1 frequency in kHz (00.1–99.9).
- "S1F:X.X.X.T": Set PWM1 frequency (0.0.1 to 1.5.0 = 1kHz to 150kHz).
- "S1DXXXT": Set PWM1 duty (001–100).
- "S2DXXXT": Set PWM2 duty (001–100).
- Using the Keypad:
- Set: Cycle through PWM1/2 frequency and duty values.
- Up/Down: Adjust selected parameter's value.
- Setting Feedback: "DOWN" for success, "FALL" for failure.
