Features:
** Range: The adjustable frequency range: from 1Hz to 150KHz.
** Clear LCD high definition Display: Display both frequency and duty cycle in more clear status. High precision detection.
** Dual work mode: Support both frequency adjustment and duty cycle adjustment.
** Power-down memory function: No need to set the data again after power-off. Knob supports lock function to avoid misoperation.
** Application: Can be used as square wave signal generator for experimental development, square wave signal generator for motor driver,

adjustable pulse generator for MCU, pulse generator, control related circuits (PWM dimming, speed regulating).
** Setting: There are 4 independent buttons on the module for setting the frequency value and the duty cycle value.

** 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
