XY-PWM1 Signal Generator Module - Adjustable PWM Pulse Frequency and Duty Cycle

The XY-PWM1 signal generator module allows you to independently set PWM output frequency and duty cycle. The frequency is divided into four ranges for auto switching:

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

Examples of frequency display:

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

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 unit or rapid changes
