Product Advantages:
1.It is very clearly to display frequency and duty cycle on LCD with housing, and PWM output can be set separately for frequency and duty cycle;
2. Wide frequency range and high accuracy;
3. Capable of serial port communication
Product Description
PWM output, frequency and duty cycle can be set separately;
The frequency is divided into four ranges and switched automatically :
1. XXX (without decimal point): The minimum unit is 1Hz;Value range:1Hz~999Hz;
2. The minimum unit of X.XX (decimal point in hundreds place) is 0.01Khz;Value range:1.00Khz~9.99Khz;
3. XX. X (decimal point to ten places): The minimum unit is 0.1Khz; Value range: 10.0KHz~99.9KHz
4. X.X.X (decimal point is between ten and hundred places): The minimum unit is 1Khz; Value range: 1KHz~150KHz
e.g. Frequency display: 100 represents PWM output of 100Hz pulses;
1.01 represents a PWM output of 1.01KHz pulses;
54.1 represents a PWM output of 54.1KHz pulses;
1.2.4 represents a PWM output of 124KHz pulses;
Duty cycle value range: 0-100%;
All set parameters, save after power down.
Parameter settings
The module has four independent buttons for setting frequency and duty cycle, and supports short pressing (increasing or decreasing by one unit) and long pressing (quickly increasing or decreasing). It is very simple, and the parameters are automatically saved after setting, without losing after power down.
Product 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: The PWM amplitude is equal to the power supply voltage;
6. Environmental temperature: -20~+70 ℃.
Range of Application:
1. Used as a square wave signal generator to generate square wave signals for experimental development;
2. Used to generate square wave signals for controlling electrical machinery drivers;
3. Generate adjustable pulses for MCU use;
4. Generate adjustable pulses and control related circuits.

1. Set the frequency of PWM
F101: the frequency is 101 Hz (001-999)
F1.05: the frequency is 1.05 KHZ (1.00~9.99)
F10.5: the frequency is 10.5KHZ (10.0~99.9)
F1.0.5: the frequency is 105KHZ (1.0.0~15.0)
2. Set the duty cycle of PWM
DXXX: the duty cycle of PWM is XXX; (001-100), such as D050, the PWM duty cycle is 50%
3. Read setting parameters
Send the 'read' string to read the set parameters.
Setting successful and return: DOWN
Setting failed and return: FALL
