HW-753 1Hz-150KHz Boost Signal Generator PWM Board Module Pulse Frequency Duty Cycle Adjustable Module
Specification:
Product size: 52*32*6mm
Product weight: 16g
Packing size: 100*100*30mm
Package weight: 16g
Module description:
PWM output, the frequency and duty cycle can be set separately the frequency is divided into four ranges,
Automatic switching: 1.XXX (no decimal point): the smallest unit is 1Hz, and the value range is 1Hz-999Hz
2. The minimum unit of X.XX (the decimal point is in the hundreds) is 0.01KHz, and the value range is 1.00KHz-9.99KHz
3.XX.X (the decimal point is in the tens place): the smallest unit is 0.1KHz the value range is 10.0KHz-99.9KHz
4. X.X.X (the decimal point is in the tens and hundreds): the smallest unit is 1KHz the value range is 100KHz-150KHz
e.g. Frequency display: 100 means PWM output pulse of 100Hz 1.01 means PWM output pulse of 1.01K 54.1 means PWM output pulse of 54.1KHz 1.2.4 means PWM output pulse of 124KHz
Duty cycle value range: 0-100% all setting parameters are saved after power-off.
Parameter settings:
The module has 4 independent buttons to set the frequency and duty cycle. It supports short press (increase or decrease by one unit) and long press (rapid increase or decrease). It is very simple. The parameters are automatically saved after setting, even if the power is off, nor is it lost.
Scope of application:
1. 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 for controlling the motor driver
3. Generate adjustable pulses for MCU use
4. Generate adjustable pulses and control related circuits (applications such as PWM dimming and speed adjustment).
Serial port control (single-chip TTL level communication)
Communication standard: 9600 bps
Data bits: 8
Stop bit: 1
Check Digit: none
Flow control: none
1. Set the frequency of PWM "F101": set the frequency to 101 Hz (001-999)
"F1.05": Set the frequency to 1.05 KHz (1.00-9.99)
"F10.5": Set the frequency to 10.5KHz (10.0-99.9)
"F1.0.5": Set the frequency to 105KHz (1.0.0-1.5.0)
2. Set the duty cycle of PWM "DXXX": Set the duty cycle of PWM to XXX (001-100) such as D050, set the duty cycle of PWM to 50%.
3. Read the set parameters Send the "read" string to read the set parameters. Here is a special note: the read data returns to a settable format, and it can be stored after power-off.
Sending Change_Read to return Read data format is one/two means that the data format returned by the read data is changed.
Note:
Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2mm measuring deviation due to manual measurement.
