Setting Parameters:
There are 4 independent buttons on the module for setting the frequency value and the duty cycle value.
Supports short press (increase or decrease one unit by one unit) and long press (fast increase or decrease).
All setting parameters will be saved when powered off to achieve data guaranteed.
Scope of application:
1. Used as a square wave signal generator to generate square wave signals for experimental development.
2.Square wave signal used to control the motor driver
3. Generate adjustable pulses for MCU use
4. The adjustable pulse is generated, the control-related circuit (PWM dimmer speed applications
Frequency Display Instruction:
The frequency is divided into 4 ranges and switched automatically.
1. XXX (without decimal point): minimum unit is 1Hz, value range is 1Hz ~ 999Hz.
2. X.XX (the decimal point is in the hundred digit): minimum unit is 0.01kHz, value range is 1.00kHz ~ 9.99kHz.
3. XX.X (the decimal point is in the ten digit): minimum unit is 0.1kHz; value range is 10.0kHz ~ 99.9kHz.
4. X.X.X (full decimal point): the minimum unit is 1kHz; the value range is 1kHz ~ 150kHz
e.g. Frequency displays 100 represents 100Hz; displays 1.01 represents 1.01kHz;
displays 54.1 represents 54.1kHz; displays 1.2.4 represents 124kHz
