Item description
The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set
the parameters automatically save, power failure Lost.
Module parameters:
- Working voltage: 3.3 ~ 30V
- Frequency range: 1Hz ~ 150KHz
- Frequency accuracy: the accuracy in each range is about 2%
- Signal load capacity: the output current can be about 5 ~ 30mA
- Output amplitude: PWM amplitude equal to the supply voltage
- Ambient temperature: -20 ~ +70 ℃.
Scope of application:
- Used as a square wave signal generator, generate square wave signal for experimental development and use
- Used to generate a square wave signal that controls the motor driver
- generate adjustable pulse for MCU use
- Generate adjustable pulse, control related circuit (PWM dimming speed and other applications)
Serial Port Control:
Communication standards: 9600 bps data bits: 8
Stop bit: 1
Check digit: none
Flow control: none
set frequency of PWM
F101: set frequency to 101HZ (001 to 999)
F1.05: set frequency to 1.05KHZ (1.00 to 9.99)
F10.5: set frequency to 10.5KHZ (10.0 to 99.9)
F1.0.5: set frequency to 105KHZ (1.0.0 to 1.5.0)set PWM duty cycle
DXXX: set PWM duty cycle to XXX: (001 to 100)
Such as D050, set PWM duty cycle is 50%
