Signal generator module PWM XY-KPWM ma button to turn on the rectangular wave generator Description: Technical Specification: Operating voltage: 3.3-30V Output current: 5-30mA Operating cycle range 0-100 percent . Frequency range: normal adjustment: 1Hz-150KHz, precise adjustment: 1Hz-15KHz. Frequency accuracy: The accuracy of each range is about 2 percent . The frequency and duty cycle are clearly displayed on the LCD screen the frequency and duty cycle are set separately za using a potentiometer ma locking function to prevent malfunction. With ON or OFF button control signal output. Support serial communication, TTL level. Used as generator of rectangular signal to generate rectangular signals for experimental development used to generate rectangular signals to control motor controllers output adjustable pulses for use output of adjustable pulses to control related circuits (dimming speed PWM, etc. application). Specification: Material: Size Chart: 71x39x25mm or 2.80x1.54x0.98 inch The package includes: 1x generator signal PWM Note: 1. 2.
