Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display 3.3V-30V 1Hz-150Khz PWM Board Module

Features:

• LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle.
• Wide frequency range, high precision.
• Serial communication, TTL level.
• The module has four independent keys, used to set the frequency and duty cycle, support touch (increase or decrease a
• unit) and long press (fast increase or decrease), set the parameters automatically save, power down not lost.

Parameter settings:

• The module has four independent keys, used to set the frequency and duty cycle, support short press (increase or decrease a unit)and long press (fast increase or decrease), very simple, set the parameters automatically save, power failure Lost.

Module parameters:

• Working voltage: 3.3 ~ 30V;
• Frequency range: 1Hz ~ 150KHz;

1. set frequency of PWM

• F101: set frequency to 101HZ (001 to 999)
• F1.05: set frequency to 1.05KHZ (1.00 to 9.99)
• F10.5: set frequency to 10.5KHZ (10.0 to 99.9)
• F1.0.5: set frequency to 105KHZ (1.0.0 to 1.5.0)

2. set PWM duty cycle

• DXXX: set PWM duty cycle to XXX: (001 to 100)
• Such as D050, set PWM duty cycle is 50%

3.read the set parameters

• Send a “read” string to read the set parameters.
• Setup successfully return: Down;
• Setup failed to return: FALL.
