Compact Adjustable PWM Module XY-PWM1

The XY-PWM1 is a compact, switchless PWM signal generator module capable of producing square and rectangular waveforms with user-adjustable frequency and duty cycle. Size: 45 mm × 28 mm × 12 mm; weight: ~15 g. Manufactured using high-quality durable materials and fine workmanship, it maintains stable output performance across ambient temperature variations and extended operational cycles. Designed for practical integration, it supports common low-voltage logic levels and interfaces directly with microcontrollers, op-amps, or manual potentiometer controls. Typical applications include benchtop electronics testing, fan speed control prototypes, PWM-based sensor excitation, and classroom demonstrations of digital signal fundamentals. Its streamlined appearance and dependable function make it suitable for both professional prototyping and self-directed learning environments.
