Quantity : 1 High-concerned chemical : none Package : TQFP is_d : Yes Supply Voltage : 3.3~30V Type : Module Origin : Mainland China Condition : New Operating Temperature : -20~+70℃

Features: 1. Dual mode, with a duty cycle step of 0.1% in fine mode; 2. The frequency and duty cycle of the LCD display are very clear, and are adjusted using a coding potentiometer, which is very convenient; PWM output can be set with frequency and duty cycle separately; 3. Equipped with locking function to prevent accidental operation; 4. Easy to operate, can set the upper and lower limits of the duty cycle; KPWM with switch, can turn on and off PWM output with one click; 5. Wide frequency range and high accuracy; 6. Easy to use, supports serial communication. Parameter: Working voltage: 3.3-30V; Frequency range: Normal mode 1Hz~150KHz; Fine mode 1HZ~15KHZ; Frequency accuracy: The accuracy in each range is about 2%; Signal load capacity: The output current can be around 5-30ma; Output amplitude: PWM amplitude is equal to the supply voltage; Environmental temperature: -20~+70 ℃. Serial port control (microcontroller TTL level communication) Communication standard: 9600 bps Data bit: 8 Stop bit: 1 Check digit: none Flow control: none Set successfully and return: DOWN; Setting failed and returned: FALL. Applicable scope: 1. Used as a square wave signal generator to generate square wave signals for experimental development; 2. Used to generate square wave signals for controlling the motor driver; 3. Generate adjustable pulses for MCU use; 4. Generate adjustable pulses and control related circuits (such as PWM dimming speed control applications). Module Description: PWM output, frequency and duty cycle can be set separately; Normal mode: Frequency range 1HZ~150KHZ duty cycle 000-100%, duty cycle step by 1% Fine mode: Frequency range 1HZ~15KHZ Duty cycle 00.0~100%, duty cycle step by 0.1% The frequency is divided into four ranges and automatically switches: 1. XXX (without decimal point): The minimum unit is 1Hz, and the value range is 1Hz~999Hz; 2. X.XX (decimal point in hundreds) has a minimum unit of 0.01 Khz and a range of values from 1.00 Khz to 9.99 Khz; 3XX X (decimal point to ten places): The minimum unit is 0.1 Khz; Value range: 10.0KHz~99.9KHz 4. X.X.X (decimal places in tens and hundreds): The minimum unit is 1 Khz; Value range: 1KHz~150KHz E. G. Frequency display: 100 represents a PWM output pulse of 100Hz; 1.01 represents a PWM output of 1.01K pulses; 54.1 represents a PWM output pulse of 54.1KHz; 1.2.4 represents a PWM output pulse of 124KHz; Duty cycle range: 0-100%; All settings parameters, save after power failure. Parameter settings: This product adjusts the frequency and duty cycle by rotating the potentiometer, which can be quickly adjusted based on the rotation speed. By default, the duty cycle is adjusted. Short press to adjust the frequency, long press for 2 seconds to lock, and long press for 5 seconds to switch modes (normal mode/fine mode). The operation is simple, and the parameters are automatically saved after setting, without losing power. Package include: Signal generator * 1 label:yes
