Description:
XY-LPWM Signal Generator Module Pulse Frequency Duty Cycle Adjustable Signal Generator LCD Display Module contains switches specifically for regulating the duty cycle and frequency. It is a two-channel PWM signal generator.
Specifications:
- Operating Voltage: 3.3-30V
- Frequency Range: 1 Hz 150 kHz
- Frequency Accuracy: 2%
- Signal Load Capacity: The output current can be about 5 30mA
- Ambient Temperature: -20 to +70°C
Features:
- XY-LPWM Signal Generator Module has a wide frequency range.
- LCD for frequency and duty cycle.
- XY-LPWM Signal Generator Module has high precision.
- Serial communication(TTL-based).
Applications:
- This is used to drive a stepper motor driver’s square wave.
- Generate an adjustable pulse for MCU.
- Generate an adjustable pulse for controlling the relative circuit (PWM adjust lightspeed, etc).
- Used as a square wave signal generator for experimental development and use.
Communication Standard:
- 9600 bps Data bits: 8
- Stop bit: 1
- Check digit: none
- Flow control: none
- Set the frequency of the PWM
“F101”: Set the frequency to 101 Hz (001 to 999)
“F1.05”: set the frequency of 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 of 105kHz (1.0.0 ~ 1.5.0)
- Set the PWM duty cycle
“DXXX”: set the PWM duty cycle to XXX; (001 ~ 100)
Such as D050, set the PWM duty cycle is 50%
- Read the set parameters
Send a “read” string to read the set parameters.
Set successfully return: DOWN
Setup failed to return: FALL.
