100% brand new and high quality

Module description:
PWM output can set frequency and duty cycle respectively.
Frequency is divided into four areas: automatic switching:
1.XXX (without decimal point): the smallest unit is 1Hz and the value range is 1Hz~999Hz;The minimum unit of
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.E.g. frequency display: 100 indicates PWM output 100Hz pulse;1.01 represents the pulse of PWM output 1.01K.54.1 represents the pulse of PWM output 54.1KHz.1.2.4 indicates the pulse of PWM output 124KHz.Duty cycle:0~100%;All settings are saved by power down.
Parameter setting:
Module has four independent keys used to set the frequency and duty cycle support short press (increase or decrease a unit) and long press (quickly increase or decrease) very simple set the parameters automatically save power loss is not lost.
Scope of application:
1.is used as a square wave signal generator to generate square wave signals for experimental development.
2.is used to generate square wave signals that control motor drives.
3.generate adjustable pulse for MCU use;
4.generate adjustable pulses to control related circuits (PWM dimming and speed regulation applications).
