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

2. LCD LCD display frequency and duty cycle, very clear, easy to adjust.

3. Wide frequency range and high accuracy;

4. Serial Communication

Used as a square wave signal generator to generate square wave signals for experimental development and use;

Square wave signal used to control motor driver;

Generate adjustable pulses for MCU use.

Generate adjustable pulses and control related circuits (PWM dimming and speed regulating applications).

The module has 8 independent keys to set the frequency and duty cycle. It supports short press (increase or decrease a unit) and long press (increase or decrease quickly). It is very simple. After setting parameters, it can save automatically without losing power.

3-way duty cycle button can be pressed at the same time, real-time adjustment, LCD display is the last pressed button duty cycle, real-time performance is very strong, can be used as a simple scan of several ways duty cycle.

Specification:

Working voltage: 3.3-30V

Frequency range: 1Hz~150KHz

Frequency accuracy: the accuracy in each range is about 2%

Signal load capacity: the output current can be about 5-30 ma

Output amplitude: PWM amplitude is equal to supply voltage

Ambient temperature: - 20°~ + 70°C

Description

Description:

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

Frequency is divided into four ranges, automatic switching:

1. XXX (no decimal point): the smallest unit is 1Hz, the range of values is 1Hz ~ 999Hz;

2. The smallest unit of X.XX (decimal point in 100 bits) is 0.01 Khz, ranging from 1.00 Khz to 9.99 Khz.

3. XX.X (decimal point in ten places): the smallest unit is 0.1Khz; the range of values is 10.0KHz~99.9KHz.

4. X.X.X (decimal point in 10 and 100 bits): the smallest unit is 1Khz; the range of values is 1KHz~150KHz

E.g. Frequency display: 100 represents the output pulse of 100 Hz from PWM;

1.01 represents the output pulse of 1.01K from PWM.

54.1 indicates that the PWM outputs 54.1KHz pulses.

1.2.4 indicates that the PWM outputs 124KHz pulses.

The duty cycle ranges from 0% to 100%, of which 100% is represented by A0%.

All setting parameters, power down save.
