1Hz ~ 150KHz Adjustable Module Duty Cycle Adjustable PWM Generator Circuit Design

Label:Yes LCD Display: The frequency and duty cycle of the LCD display are very clear. This module can communicate with serial port. All setting parameters are saved after power off. Easy To Operate: PWM output, this module can set the frequency and duty cycle separately, with wide frequency range and high accuracy. Four Frequency Range, Automatic Switching: XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz, X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz, XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz, X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz. Scope Of Application: Used as square wave signal generator to generate square wave signals for experimental development and use to generate square wave signals for controlling motor drivers. Generate Adjustable Pulses: This module generates adjustable pulses for MCU use and control related circuits (applications such as PWM dimming and speed regulation).

Specification Item Type: Signal Generator Module Material: Plastic Frequency range is divided into four, automatic switching: 1.XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz; 2.X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz; 3.XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz 4.X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz e.g. frequency display: 100 indicates that the PWM output pulse of 100Hz; 1.01 represents the PWM output pulse 1.01K; 54.1 represents the PWM output pulse 54.1KHz; 1.2.4 indicates that the PWM output pulse of 124KHz; Duty cycle range: 0 to 100% All setup parameters, power down save.

Module Parameters: Working Voltage: 3.3 ~ 30V Frequency range: 1Hz ~ 150KHz The frequency accuracy: in each range accuracy is about 2% Load capacity signal: output current of about 5 ~ 30ma The output amplitude: PWM amplitude equal to the supply voltage Ambient temperature: -20 ~ + 70 ℃ Size: 52*32mm(2.05*1.26in) Color: As picture shown

The Serial Port Control (MCU TTL level communications) Communication Standard: 9600 bps Data bits: 8 Stop Bits: 1 Parity Bit: None Flow Control: None
