1x Adjustable PWM Signal Generator With LCD DIsplay TTL Serial Interface

[Features]

  • With Blue LCD display, clearly display outpur frequency and duty cycle
  • Wide frequency range and high precision
  • Manual adjustable PWM frequency and duty cycle
  • Able to setting through TTL Serial communication
  • Output PWM amplitude can be set from 3.3V to 30V (Follow input power)
  • Setting parameters automatic save during power down
  • Duty cycle range: 0 ~ 100%
  • Frequency range: 1Hz ~ 150kHz

[Specifications]

  • 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 ~ 30ma;
  • Output amplitude: PWM amplitude equal to the supply voltage;
  • Ambient temperature: -20 ~ +70 DegC

[Setting]
Frequency is divided into four ranges, automatic switching:

  • XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz;
  • X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz;
  • XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz
  • X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz

example:-

  • frequency display:
  • 100 indicates PWM output 100Hz pulse;
  • 1.01 indicates PWM output 1.01K pulse;
  • 54.1 indicates that the PWM output has a pulse of 54.1 kHz;
  • 1.2.4 indicates that the PWM output is 124 kHz pulse;

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)

[Application]

  • Used as a square wave signal generator, generate square wave signal for experimental development and use
  • Used to generate a square wave signal that controls the motor driver
  • generate adjustable pulse for MCU use
  • generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications).

[Serial Communication]
* Serial control (single-chip TTL level communication)
* Communication standard:

  • 9600 bps Data bits: 8
  • Stop bit: 1
  • Check digit: none
  • Flow control: none

1)Set the frequency of the PWM

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

2)Set the PWM duty cycle

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

3)Read the set parameters

  • Send a "read" string to read the set parameters.
  • Set successfully return: DOWN;
  • Setup failed to return: FALL.
