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:
- XXX (no decimal point): The smallest increment is 1Hz, with values ranging from 1Hz to 999Hz.
- X.XX (hundredth place decimal point): The unit here is 0.01 kHz, with values ranging from 1.00 kHz to 9.99 kHz.
- 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.
- 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:
- Generate square wave signals for experimental developments as a signal generator.
- Create square wave signals to control motors.
- Produce adjustable pulses for MCU use.
- Generate modifiable pulses to control related circuits (‘useful in PWM dimming and speed regulation).
