Description

Module Overview: The module is equipped with programmable pulse-width modulation (PWM) output. Specific frequency and duty cycle can be set independently with this feature.

For ease of use, frequencies are categorised into four sections with automatic shifting:

1. XXX (no decimal point): The smallest increment is 1Hz, with values ranging from 1Hz to 999Hz.
2. X.XX (hundredth place decimal point): The unit here is 0.01 kHz, with values ranging from 1.00 kHz to 9.99 kHz.
3. XX.X (decimal point in the tens place): The smallest increment here is 0.1 kHz with a range between 10.0 kHz to 99.9 kHz.
4. X.X.X (decimal points in the tens and hundredths places): Here, the smallest unit is 1 kHz, and the range spans from 1KHz to 150KHz.

By way of example, a frequency display of 1.01 signifies a PWM output pulse of k.54.1 and a display of 100 corresponds to a 100Hz PWM output pulse.

The duty cycle is adjustable from 0% to 100%, with all set parameters retained even after power-off.

User-Friendly Design: Four individual keys are included on the module for ease of frequency and duty cycle settings. Whether you need to increase or decrease by just one unit or need a quick change, a short press or a long press is all you need. The settings will be automatically saved, shielding against any data loss due to power off.

Usage: This module can form a crucial part of many systems as it can:

1. Generate square wave signals for experimental developments as a signal generator.
2. Create square wave signals to control motors.
3. Produce adjustable pulses for MCU use.
4. Generate modifiable pulses to control related circuits (useful in PWM dimming and speed regulation).
