Lyla PWM Pulse Frequency Duty Cycle Adjustable Square Wave Signal Generator Module LC

Description:LCD liquid crystal display frequency and duty cycle are very clear.Two independent PWM generators can set the frequency, duty cycle.The wide frequency range, high accuracy.Can serial communication.Frequency is divided into four ranges, automatic switching:1. XXX (without decimal point): the smallest unit is 1Hz, and the value range is 1Hz~999Hz.2. X.XX (decimal point in 100 bits) is 0.01Khz, and the value range is 1.00Khz~9.99Khz.3. XX.X (decimal point in ten places): the smallest unit is 0.1Khz; and the range is 10.0KHz~99.9KHz.4. X.X.X (decimal point in ten bits and 100 bits): the smallest unit is 1Khz; and the range is 1KHz~150KHz.Frequency display:100 indicates PWM output 100Hz pulse1.01 is the pulse of the PWM output 1.01K54.1 is the pulse of the PWM output 54.1KHz1.2.4 represents the pulse of the PWM output 124KHz.The range of duty ratio: 0~100%Specification:Working voltage: 3.3~30VFrequency range: 1Hz~150KHzFrequency Accuracy: about 2%Signal load capacity: Output current about 5~30maOutput amplitude: PWM amplitude is equal to the supply voltageEnvironmental temperature: -20~+70℃Size: 5 x 4cm/2 x 1.6inchPackage Includes:1 Piece Signal Generator Module
