Feature:
1.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
PWM output, you can set the frequency, duty cycle;
Working voltage: 3.3 ~ 30V;
Frequency range: 1Hz ~ 150KHz;
Description:
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
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;
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 decrease), 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 ¡æ.
The 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).
Serial control (single-chip TTL level communication)
Communication standard:
9600 bps Data bits: 8
