Triple-Channel PWM Generator with Display

The 3-channel PWM signal generator module with a digital display is capable of generating adjustable square-wave pulses. Using three independent PWM channels, it allows simultaneous adjustment of both the duty cycle and the frequency.

PWM Pulse Generator offers high accuracy and a wide frequency range, and it can be used as a signal generator to produce adjustable pulses and control related circuits. The PWM signal generator module features 8 independent control buttons for simultaneous configuration of the three PWM outputs. The frequency is adjustable, all three channels provide compatible frequency outputs, and the duty cycle of each channel can be adjusted independently.

PWM Frequency Adjustment

“F101”: Sets the frequency to 101 Hz (range: 001–999 Hz)

“F1.05”: Sets the frequency to 1.05 kHz (range: 1.00–9.99 kHz)

“F10.5”: Sets the frequency to 10.5 kHz (range: 10.0–99.9 kHz)

“F1.0.5”: Sets the frequency to 105 kHz (range: 100–150 kHz)

PWM Duty Cycle Adjustment

“DX:YYY”:

X = PWM channel number (1–3)

YYY = Duty cycle percentage (000–100)
