1Hz-150Khz Signal Generator PWM Board Adjustable Module Pulse Frequency

Module Description

PWM output, you can set the frequency, duty cycle;

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 of10.0KHz~99.9KHz

X.X.X (decimal point in ten and hundred): the smallest unit is 1Khz; value range1KHz ~ 150KHz

Frequency display

100 indicates PWM output100Hz pulse;

1.01 indicates PWM output 1.01K pulse;

54.1 indicates that the PWM output has a pulse of 54.1kHz;

1.2.4 indicates that the PWM output is 124kHz pulse;

Duty cycle range:0~100%;

All set parameters, power-down automatically saved.

Parameter settings 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 de- crease), set the parameters automatically save, power down Not lost. 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℃. Scope of 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).
