Condition: 100% Brand New Item Type: Signal Generator Module Material: Plastic Color: Blue, Black (Optional) Duty Cycle Value Range: 0-100% Size: Approx. 32x52mm / 1.3x2.0in Module Description: PWM output can be set frequency and duty cycle respectively. Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, ranging from 1Hz - 999Hz 2. X.XX (decimal point in 100 bits): the smallest unit is 0.01 Khz, ranging from 1.00Khz - 9.99Khz. 3. XX.X (decimal point in ten places): the smallest unit is 0.1Khz the range of values is 10.0KHz-99.9KHz. 4. X.X.X (decimal point in 10 and 100 bits): the smallest unit is 1Khz the range of values is 1KHz-150KHz1As a square-wave signal generator, square-wave signal is generated for experimental development. 2Used to generate a square wave signal that controls the motor driver. 3With LCD display, frequency and duty cycle can be visually displayed. 4PWM output can set frequency and duty cycle respectively, and can communicate with serial port. 5It has wide frequency range and high precision. It generates adjustable pulses and controls related circuits. 1 x Signal Generator Module
