3-way PWM Pulse Adjustable Frequency Module for Square Wave Signal Generator Adjustable Duty Ratio I

Feature:1. 3-way PWM output, adjustable frequency, 3-way frequency output consistent, duty cycle can be adjusted independently, suitable for most occasions;

2. LCD liquid crystal display frequency and duty cycle, very clear, very convenient to adjust

3. Wide frequency range, high precision;

4. Serial communication 

Description:

3-way PWM output, wide frequency range, duty cycle can be adjusted independently in real time;

Frequency is divided into four ranges, automatic switching:1. XXX (no decimal point): the minimum unit is 1Hz, the value range is 1Hz~999Hz;

2. X.XX (decimal point in the hundreds place) the minimum unit is 0.01Khz, the value range is 1.00Khz~9.99Khz;

3. XX.X (decimal point in the tens place): the minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz

4. X.X.X (decimal point in tens and hundreds):
