1Hz–150KHz Adjustable Signal Generator Module (3.3V–30V)

This is a high-performance signal generator module capable of producing square wave signals with adjustable frequency, duty cycle, and amplitude. It features an intuitive interface with an LCD display and button controls, making it suitable for various electronic development, testing, and MCU applications.

Key Features:

• Fully Adjustable: Frequency, duty cycle, and amplitude are all adjustable. Upper and lower limits can be set independently.
• Dual Mode: Normal mode frequency range is 1Hz–150KHz; fine-tune mode supports 1Hz–15KHz for precision adjustment.
• LCD Display: Real-time display of frequency, duty cycle, and amplitude. Includes ON/OFF button control for convenient operation.
• Output Range: DC 1V–24V at 3W max. Can also function as a 3W digital controlled power supply.
• Memory Function: All settings are retained after power-off. Lock feature prevents accidental operation.
• Square Wave Output: Generates square wave signals for experiment development and MCU-controlled circuit triggering.
