Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module With LCD Display and Case 1Hz-150Khz 3.3V-30V Description: Features: - Support Serial operation - Wide frequency range,high precision - LCD can display frequency and duty datio,Easy to oprate - Output of three-channel PWM at the same time - Adjustable Frequency,3-channel frequency output consistent,duty ratio can be independently adjusted,suitable for most occasions Specifications: 1.Operating voltage3.3~30V; 2. Frequency range1Hz~150KHz; 3. Frequency accuracy:In each range of accuracy is about 2% 4. Signal load capacity:Output current can be around 5~30ma 5. Output amplitude: PWM amplitude and supply voltage equal 6. Ambient temperature:-20~+70° 7. Size:5.5x3.8cm/2.17x1.50inch Overview: 1. Module has 4 independent keys,used to set the frequency and duty ratio,support short press (increase or decrease a unit) and long press (fast increase or decrease),very simple,set the parameters automatically save,power loss. 2. 3-Way duty ratio button can be pressed at the same time,real-time adjustment, liquid crystal display is the last pressed button duty ratio,real-time is very strong,can be used as a simple several road duty ratio scan. Parameter Settings: Three-channel PWM is outputted,wide frequency range and the duty ratio can be adjusted independently Frequency is divided into four areas,automatic switching: 1.XXX(No decimal point): 1HZ Stepping Unit,Range:1Hz~999Hz; 2.X.XX(The decimal is in hundreds place):0.01KHZ Stepping Unit,Range: 1.00Khz~9.99Khz; 3.X.XX(The decimal is in the tens place):0.1KHZ Stepping Unit,Range: 10.0Khz~99.9Khz; 4.X.X.X(The decimal is in the ones place):1KHZ Stepping Unit,Range: 1Khz~150Khz; e.g. ,frequency display:100 represent the pulse of 100Hz ; 1.01 represent the pulse of 1.01KHz; 54.1 represent the pulse of 54.1KHz 1.2.4 represent the pulse of 124Hz The value range of dutyfactor: 0~100%,100% is represented by A0%. All parameters setted up can be automatically saved in case of power cut. Application: 1.Used as square wave signal generator to generate square wave signal for experiment development and use 2.Used to generate a square wave signal to control the motor driver; 3.Generating adjustable pulses for MCU use; 4.Generate adjustable pulse, control related circuit (PWM dimming speed and other applications). UART Serial Command: Baud rate:9600 bps Data length:8 Stop bits:1 Check digit:none Flow control:none 1.set the frequency of the PWM “F101”: Set frequency of 101 HZ (001~999) “F1.05”: Set frequency of 1.05 KHZ(1.00~9.99) “F10.5”: Set frequency of 10.5KHZ(10.0~99.9) “F1.0.5”:Set frequency of 105KHZ(1.0.0~1.5.0) 2.set the duty ratio of PWM "DX:YYY": Set PWM duty ratio x: (1~3) PWM serial number,YYY: (000~100) duty ratio; For example d1:050,set 1th PWM duty ratio to 50% 3.Read Setup parameters Send a "read" string to read the parameters of the setting.
