Highlights: Two independent PWM generators can set the frequency, duty cycle; The wide frequency range, high accuracy; Can serial communication. First, the module description£ºFrequency is divided into three ranges:XXX (no decimal point): the smallest unit is 1Hz, the range 1Hz ~ 999Hz;XX.X (decimal point in ten): The minimum unit is 0.1Khz; the range of 0.1KHz ~ 99.9KHzX.X.X. (there are three decimal point): the smallest unit is 1Khz; the range 1KHz ~ 150KHzFrequency display example:"100" indicates that the PWM output pulse of 100Hz;"54.1" indicates that the PWM output pulse of 54.1KHz;"1.2.4." Indicates that the PWM pulse output 124KHzDuty Cycle in the range: 0 to 100;Three frequencies duty cycle is the same, all the parameters non-volatile.Second, the module parameters:Working voltage: 5--30V, support micro USB 5.0V power supply;Frequency range: 1Hz ~ 150KHz;The frequency accuracy: ¡À 2%;Output Current: <30mA;Output amplitude: Default 5Vp-p (settable);Operating temperature rang
