Description
Features: LCD display frequency and duty cycle very clear PWM output can set frequency and duty cycle; Wide frequency range and high precision; Serial communication TTL level; Module Features: PWM output frequency and duty cycle can be set; The frequency is divided into four ranges which are automatically switched: XXX (without decimal point): the minimum unit is 1Hz and the value range is 1Hz-999Hz; The minimum unit of X.XX (hundreds decimal point) is 0.01Khz and the range is 1.00Khz-9.99Khz; X XX (decimal decimal): the minimum unit is 0.1Khz; the value range of 10.0KHz-99.9KHz XXX (decimal points of tens and hundreds): the minimum unit is 1Khz; the value range is 1KHz - 150KHz Frequency display: 100 means PWM output 100Hz pulse; 1.01 means PWM output 1.01K pulse; 54.1 means the PWM output has a 54.1 kHz pulse; 1. 1.4 means the PWM output is 124kHz pulse; Duty cycle range: 0 - ; After all parameters are set it will be automatically saved when power off. parameter settings: The module has four buttons for setting frequency and duty cycle supports touch (increase or decrease unit) and Long press (fast increase or decrease) the parameters are automatically adjusted and saved and the power will not be lost. Module parameters: Working voltage: 3.3-30V; Frequency range: 1Hz - 150KHz; Frequency accuracy: the accuracy of each range is about 2%; Signal load capacity: the output current can be around 5-30mA; Output amplitude: PWM amplitude is equal to supply voltage; Ambient temperature: -20 - +70 degrees Application: Used as a square wave signal generator to generate square wave signals for development and experimentation; Used to generate square wave signal to control motor driver; Generate adjustable pulses for MCU use; Generate adjustable pulses to control corresponding circuits (applications such as PWM dimming speed). Serial control (single-chip TTL level communication) Communication Standard: 9600 bps data bits: 8 stop bit: 1 Check Digit: None Fl ow Control: None 1. Set the PWM frequency F101 : Adjust the frequency to 101HZ (001 to 999) F1.05 : Set the frequency to 1.05KHZ (1.00-9.99) F10.5 : set the frequency to 10.5KHZ (10 0-99.9) F1.0.5 : set the frequency to 105KHZ (1.0.0 - 1.5.0) 2. Set the duty cycle PWM DXXX : PWM to XXX set duty cycle; (001-2008). Like the D050 the PWM duty cycle is 50%. 3. Read the setting parameters Send the read string to read the setup parameters. Set the correct return: down; Return configuration failure: fall. Package includes: 1*Module
