module description
PWM output, frequency and duty cycle can be set separately;
Frequency is divided into four ranges, automatic switching:
1.XXX (no decimal point): the minimum unit is 1Hz, and the value range is 1Hz~999Hz;
2. X.XX (the decimal point is in the hundreds place) the smallest unit is 0.01Khz, and the value range is 1.00Khz~9.99Khz;
3.XX.X (decimal point in tens): the minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz
4.X.X.X (decimal point in tens and hundreds): the minimum unit is 1Khz; the value range is 1KHz~150KHz
e.g. Frequency display: 100 means PWM output 100Hz pulse
1.01 means PWM output 1.01K pulse
54.1 means PWM output 54.1KHz pulse
1.2.4 means PWM output 124KHz pulse
Duty cycle range: 0-100%
All setting parameters, save when power off
parameter settings
The module has 4 independent buttons, which are used to set the frequency and duty cycle. It supports short press (increase or decrease by one unit) and long press (increase or decrease quickly). lost
Module parameters:
1. Working voltage: 3.3-30V
2. Frequency range: 1Hz-150KHz
3. Frequency accuracy: the accuracy in each range is about 2%
4. Signal load capacity: the output current can be around 5~30ma
5. Output amplitude: PWM amplitude is equal to the supply voltage
6. Ambient temperature: -20~+70℃
7. Product size: 78mm*42mm*25mm
Scope of application:
1. Used as a square wave signal generator to generate square wave signals for experimental development
2. Used to generate a square wave signal to control the motor driver
3. Generate adjustable pulses for MCU use
4. Generate adjustable pulses and control related circuits (PWM dimming and speed regulation and other applications)
Serial port control (MCU 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)
For example, D050, set the PWM duty cycle to 50%
3. Read setting parameters
Send the \"read\" string to read the set parameters
Set successfully return: DOWN
Setting failed to return: FALL
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 1-2cm measuring deviation due to manual measurement.
