Signal Generator Module Adjustable PWM Pulse Frequency Duty Cycle Square Wave
2.LCD liquid crystal display frequency and duty cycle, very clear, using the coding potentiometer adjustment, very convenient; PWM output can be set separately for frequency and duty cycle.
3. With locking function to prevent misoperation.
4. Simple operation, can set the upper and lower limits of the duty cycle; KPWM with a switch, you can turn on and off the PWM output with one key.
5. Wide frequency range, high precision.
6. Easy to use, support serial communication.
Operating voltage: 3.3~30V;
Frequency range: ordinary mode 1Hz~150KHz; fine mode 1HZ~15KHZ;
Frequency accuracy: the accuracy on each range is about 2%;
Signal loading capacity: output current can be around 5~30ma;
Output amplitude: PWM amplitude is equal to the supply voltage;
Ambient temperature: -20~+70℃.
Serial port control (microcontroller TTL level communication)
Communication standard:9600 bps
Data bits: 8
Stop bit: 1
Parity bit: none
Flow control: none
Return from successful setting: DOWN;
Setting failure return: FALL.
Scope of application:
1. Used as a square wave signal generator to produce square wave signals for experimental development;
2. Used to generate square wave signals for controlling motor driver;
3. Generate adjustable pulses for MCU use;
4. Generate adjustable pulses to control related circuits (PWM dimming and speed control and other applications).
PWM output, you can set the frequency and duty cycle separately;
Common mode:
Frequency range 1HZ~150KHZ Duty cycle 000~100%, duty cycle step 1%
Fine mode:
Frequency range 1HZ~15KHZ Duty cycle 00.0~100%, duty cycle step 0.1%.
Frequency is divided into four ranges with automatic switching:
1.XXX (no decimal point): the smallest unit is 1Hz, value range 1Hz~999Hz;
2.X.XX (decimal point in hundredths): the smallest unit is 0.01Khz, value range 1.00Khz~9.99Khz;
3.XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range 10.0Khz~99.9Khz
4.X.X.X (decimal point in tenth and hundredth place): the smallest unit is 1Khz; the value range is 1KHz~150KHz.
e.g. Frequency Display:
100 means PWM outputs 100Hz pulse;
1.01 means PWM outputs 1.01K pulse;
54.1 means PWM outputs 54.1KHz pulse;
1.2.4 means PWM outputs 124KHz pulse;
Duty cycle value range: 0~100%;
All setting parameters, power-down save.
This product through the rotary potentiometer to adjust the frequency and duty cycle, according to the rotary speed judgment to achieve rapid adjustment, the default adjustment of the duty cycle, short press to adjust the frequency, long press 2 seconds to lock, long press 5 seconds to switch the mode (ordinary mode / fine mode), easy to operate, set up the parameters are automatically saved, power-down will not be lost.
