Description:

LCD display frequency and duty cycle, very clear, PWM output, can be set to the frequency and duty cycle.
Wide frequency range, high precision.
Serial communication, TTL level.
Frequency is divided into four ranges, automatic switching.
All set parameters, power-down automatically saved.
Application Range:
1. Used as a square wave signal generator, generate square wave signal for experimental development and use;
2. Used to generate a square wave signal that controls the motor driver;
3. generate adjustable pulse for MCU use;
4. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).

Specification:

Frequency is divided into four ranges, automatic switching:
1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
