Parameter settings: The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically save, power failure Lost. 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 ℃. 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 related circuit (PWM dimming speed and other applications) Serial Port Control: Communication standards: 9600 bps data bits: 8 Stop bit: 1 Check digit: none Flow control: none 1. set frequency of PWM F101: set frequency to 101HZ (001 to 999) F1.05: set frequency to 1.05KHZ (1.00 to 9.99) F10.5: set frequency to 10.5KHZ (10.0 to 99.9) F1.0.5: set frequency to 105KHZ (1.0.0 to 1.5.0) 2. set PWM duty cycle DXXX: set PWM duty cycle to XXX: (001 to 100) Such as D050, set PWM duty cycle is 50% 3.read the set parameters Send a "read" string to read the set parameters. Setup successfully return: Down; Setup failed to return: FALL. Package included: 5 x 1Hz-150Khz 3.3V-30V Signal Generator
