Module description

Three-channel PWM is outputted, wide frequency range and the duty ratio can be adjusted independently;

Frequency is divided into four areas, automatic switching:

XXX (No decimal point): 1HZ Stepping Unit, Range: 1Hz~999Hz;

X (The decimal is in the hundreds place): 0.01KHZ Stepping Unit, Range: 1.00Khz~9.99Khz;

XX(The decimal is in the tensplace): 0.1KHZ Stepping Unit, Range: 10.0Khz~99.9Khz;

 X.X(The decimal is in the onesplace): 1KHZ Stepping Unit, Range: 1Khz~150Khz;

E.g. , frequency display: 100 represent the pulse of 100Hz ;

1.01 represent the pulse of 1.01KHz;

54.1 represent the pulse of 54.1KHz

1.2.4 represent the pulse of 124Hz

The value rangeof dutyfactor: 0~100%, 100% is represented by A0%.

All parameters setted up can be automatically saved in case of power cut.

 Parameter settings

Module has 8 independent keys, used to set the frequency and duty ratio, support short press (increase or decrease a unit) and long press (fast increase or decrease), very simple, set the parameters automatically save, power loss.

3-Way duty ratio button can be pressed at the same time, real-time adjustment, liquid crystal display is the last pressed button duty ratio, real-time is very strong, can be used as a simple several road duty ratio scan.

Third, Module Parameters:

1.Operating voltage: 3.3~30V;

Frequency range: 1Hz~150KHz;

Frequency accuracy: In each range of accuracy is about 2%

Signal load capacity: Output current can be around 5~30ma

Output amplitude: PWM amplitude and supply voltage equal

Ambient temperature: -20~+70°C.

 Scope of application:

Used as square wave signal generator to generate square wave signal for experiment development and use

Used to generate a square wave signal to control the motor driver;

Generating adjustable pulses for MCU use;

Generate adjustable pulse, control related circuit (PWM dimming speed and other applications).

UART Serial command

Baud rate: 9600 bps Data length: 8

Stop bits :1

Check digit:none

Flow control: none

Set the frequency of the PWM

“F101”: Set frequency of 101 HZ (001~999)

“F1.05”: Set frequency of 1.05 KHZ (1.00~9.99)

“F10.5”: Set frequency of 10.5KHZ (10.0~99.9)

“F1.0.5”: Set frequency of 105KHZ (1.0.0~1.5.0)

Set the duty ratio of PWM

“DX:YYY”: Set PWM duty ratio x: (1~3) PWM serial number, YYY: (000~100) duty ratio;

For example d1:050, set 1th PWM duty ratio to 50%

Read Setup parameters

Send a “read” string to read the parameters of the setting.

Message format: F156, D1: 052, D2: 059, D3: 058,

Set successful return: DOWN

Set failed to return: FALL
