Description: Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display 1Hz-150Khz 3.3V-30V PWM Board Module Module highlights 1. Three-way PWM output, adjustable frequency, three-way frequency output, duty cycle can be adjusted independently, suitable for most occasions; 2. LCD liquid crystal display frequency and duty cycle, very clear, very easy to adjust 3. Wide frequency range and high accuracy; 4. Serial communication Module Description 3-way PWM output, wide frequency range, duty cycle can be adjusted independently in real time; The frequency is divided into four ranges, automatically switching: 1.XXX (no decimal point): The minimum unit is 1Hz, the value range is 1Hz~999Hz; 2.X.XX (the decimal point is in the hundred place) is 0.01Khz, the value range is 1.00Khz~9.99Khz; 3.XX.X (decimal point in ten): The minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz 4.X.X.X (decimal point in ten and hundreds): The minimum unit is 1Khz; the value range is 1KHz~150KHz E.g. Frequency display: 100 represents the PWM output 100Hz pulse; 1.01 represents the PWM output 1.01K pulse; 54.1 indicates the PWM output 54.1KHz pulse; 1.2.4 indicates PWM output pulse of 124KHz; Duty cycle values range from 0 to 100%, where 100% is expressed in A%. All setting parameters are saved after power off. Parameter Settings The module has 8 independent keys to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), it is very simple, set parameters automatically save, power off is not Lost. The 3-way duty-cycle button can be pressed at the same time, real-time adjustment, LCD display is the duty cycle of the last pressed button, real-time is very strong, can be used as a simple several-way duty cycle scan. 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 around 5~30ma; 5. Output amplitude: PWM amplitude and supply voltage are equal; 6. Ambient temperature: -20~+70°C. The Scope Of Application 1. It is used as a square wave signal generator to generate square wave signals for experimental development and use; 2. Used to generate a square wave signal to control the motor driver; 3. Generate adjustable pulses for use by the MCU; 4. Generate adjustable pulses, control related circuits (PWM dimming speed control applications). Serial Control (Single-chip TTL level communication) Communication standard: 9600 bps Data bit : 8 Stop bit :1 Check digit :none Flow control :none 1. Set the PWM frequency "F1.0.5": The setting frequency is 105KHZ (1.0.0~1.5.0) 2. Set the PWM duty cycle "Dx:yyy": set the duty cycle of the PWM x: (1 ~ 3) PWM serial number, yyy: (000 ~ 100) duty cycle%; For example, D1:050, set the 1st PWM duty cycle to 50%. 3. Read the setting parameters Send "read" string to read the set parameters. The read data format is as follows: F156, D1: 052, D2: 059, D3: 058, Successfully set return: DOWN; Failed to set return: FALL. Package Included: 1 x Signal Generator PWM Pulse Frequency Adjustable Module LCD Display 3 Channels Instructions/schematic are NOT included.
