XY-PWM1 Signal Generator Module

The XY-PWM1 is a signal generator module that allows you to independently adjust the output frequency and duty cycle of a PWM signal. The frequency is divided into four ranges for automatic switching:

• XXX: No decimal, the minimum unit is 1 Hz, the range is 1 Hz ~ 999 Hz
• X.XX: Decimal at hundreds, the minimum unit is 0.01 KHz, the range is 1.00 KHz ~ 9.99 KHz
• XX.X: Decimal at tenths, the minimum unit is 0.1 KHz, the range is 10.0 KHz ~ 99.9 KHz
• X.X.X: Decimal at tens and hundreds, the minimum unit is 1 KHz, the range is 1 KHz ~ 150 KHz

Examples of frequency display:

• 100→ PWM pulse output at 100 Hz
• 1.01→ PWM pulse output at 1.01 KHz
• 54.1→ PWM output at 54.1 KHz
• 1.2.4→ PWM output at 124 KHz

Additional Features:

• Duty cycle: 0% ~ 100%
• All settings are retained after power off
• Four independent buttons allow easy parameter adjustment
• Supports short and long presses for single or rapid changes

Applications:

• Used as a square wave signal generator for development
