Wide frequency range, high precision; 3. Serial communication, TTL level First, the module description PWM output, you can set the frequency, duty cycle; Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; 2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; 3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz 4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz frequency display: 100 indicates PWM output 100Hz pulse; 1.01 indicates PWM output 1.01K pulse; 54.1 indicates that the PWM output has a pulse of 54.1 kHz; 1.2.4 indicates that the PWM output is 124 kHz pulse; Duty cycle range: 0 ~ 100%; All set parameters, power-down automatically saved. Second, the parameter settings The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a unit) and long press (fast increase or decrease), set the parameters automatically save, power down Not lost. Third, the module parameters: 1. Working voltage: 3.3 ~ 30V; 2. Frequency range: 1Hz ~ 150KHz; 3. Frequency accuracy: the accuracy in each range is about 2%; 4. Signal load capacity: the output current can be about 5 ~ 30ma; 5. Output amplitude: PWM amplitude equal to the supply voltage; 6. Ambient temperature: -20 ~ +70 \u2103. Fourth, the scope of application: 1. Used as a square wave signal generator, generate square wave signal for experimental development and use; 2. Used to generate a square wave signal that controls the motor driver; 3. generate adjustable pulse for MCU use; 4. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications). 5, serial control (single-chip TTL level communication) Communication standard: 9600 bps Data bits: 8 Stop bit: 1 Check digit: none Flow control: none 1, set the frequency of the PWM \"F101\": Set the frequency to 101 HZ (001 to 999) \"F1.05\": set the frequency of 1.05 KHZ (1.00 ~ 9.99) \"F10.5\": Set the frequency to 10.5KHZ (10.0 ~ 99.9) \"F1.0.5\": set the frequency of 105KHZ (1.0.0 ~ 1.5.0) 2, set the PWM duty cycle \"DXXX\": set the PWM duty cycle to XXX; (001 ~ 100) Such as D050, set the PWM duty cycle is 50% 3, read the set parameters Send a \"read\" string to read the set parameters. Set successfully return: DOWN; Setup failed to return: FALL. Package Includes: 1x PWM pulse frequency duty cycle adjustable module"}
