Description

  • LCD display frequency and duty cycle, very clear, PWM output can be set to the frequency and duty cycle;
  • Wide frequency range, high precision;Duty cycle range: 0 ~ 100%;
  • 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.

Frequency is divided into four ranges, automatic switching: 1. XXX (no decimal point): the smallest unit is 1Hz, the value range of 1Hz ~ 999Hz; 2. X.XX (decimal point in the hundred) the smallest unit is 0.01Khz, the range of 1.00Khz ~ 9.99Khz; 3. XX.X (decimal point in ten): the smallest unit is 0.1Khz; value range of 10.0KHz ~ 99.9KHz 4. X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range 1KHz ~ 150KHz 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 parameters: 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 ℃. Fourth, the scope of application: 1. Used as a square wave signal generator, generate square wave signal for experimental development and use; 2. Used to generate a square wave signal that controls the motor driver; 3. generate adjustable pulse for MCU use; 4. generate adjustable pulse, control the relevant circuit (PWM dimming speed and other applications). 5, serial control (single-chip TTL level communication) Package Includes: 1x PWM pulse frequency duty cycle adjustable module
