XY-PWM Signal Generator Module

The XY-PWM signal generator module is a versatile and user-friendly tool for generating precise square or rectangular signals. With its wide frequency range, easy-to-use LCD display, and support for TTL serial communication, it is ideal for developers, lab technicians, and electronics hobbyists.

Main Features:

• Wide Frequency Range: Adjustable from 1 Hz to 150 kHz with 4 frequency ranges for high precision.
• Clear LCD Display: Shows the current frequency and duty cycle in real time.
• Adjustable Duty Cycle: Ranges from 0% to 100% with settings saved when powered off.
• Serial Communications: Supports TTL level UART commands for controlling frequency and duty cycle.
• Simple Controls: The four-button interface supports short and long presses for quick parameter adjustment.

Frequency Display Format:

• XXX: From 1 Hz to 999 Hz (e.g., 100= 100 Hz)
• X.XX: 1.00 kHz to 9.99 kHz (e.g., 1.01= 1.01 kHz)
• XX.X: 10.0 kHz to 99.9 kHz (e.g., 54.1 = 54.1 kHz)
• X.X.X: 100 kHz to 150 kHz (e.g., 1.2.4= 124 kHz)
