【Friends Welcome to #OlahragaOutdoorElektronik# store , If you love our products, please click and give me five-star✧✧✧✧✧thanks. My product is very good quality, my price is also very Cost-effective, my friends, just enjoying your shopping here, come on baby!】


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;
Serial communication, TTL level

First, the 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 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.

Second, the 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.

Third, 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:
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).
5, 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.

Package Included:
