Features:

1. Two independent PWM outputs, which can set the frequency and duty cycle respectively;

2. Wide frequency range and high precision;

3. Serial communication

4. Two independent PWM outputs, which can set the frequency and duty cycle respectively;

5. The duty ratio ranges from 0 to 100;

6. The three frequency ranges share a duty cycle, and all setting parameters are saved after power down.

Parameter:

1. Working voltage: 5--30V supports micro USB 5.0V power supply;

2. Frequency range: 1Hz~150KHz;

3. Frequency accuracy: the accuracy in each range is about 2%;

4. Signal load capacity: the output current can be around 8--30ma;

5. Output amplitude: default 5V V-pp (can be changed by external power supply);

6. Ambient temperature: -30~+70°C.

Parameter Settings:

The frequency is divided into three ranges:

1. XXX (no decimal point): the small unit is 1 Hz, and the value ranges from 1 Hz to 999 Hz.

2. XX.X (decimal point is ten): small unit is 0.1Khz; value range is 0.1KHz~99.9KHz

3. X.X.X. (three digits have a decimal point): small unit is 1Khz; value range 1KHz~150KHz

Frequency display: (example)

100 denotes a pulse of PWM output of 100 Hz;

54.1 indicates that the PWM outputs a pulse of 54.1 kHz;

1.2.4. Indicates PWM output 124KHz pulse

The module has three buttons: Set, Up, Down;

1. By short pressing the [Set] key, the display of four parameter values (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: PWM2 frequency; dU2: PWM2 duty cycle), there will be corresponding parameters before switching Name flashing prompt.

2. Press [Up] and [Down] directly to modify the current parameter value (long press can be added quickly or quickly).

3. The two PWMs are pre-configured with three kinds of frequency values. In the frequency display interface, the long-pressing [SET] key is used to switch, and the duty ratios of the three frequencies are the same. (XXX: range 1Hz~999Hz; XX.X: range 0.1Khz~99.9Khz; X.X.X.: range 1Khz~150Khz,).

1, set the frequency of the PWM

“S1FXXXT”: Set the frequency of PWM1 to XXX HZ (001~999)

“S1FXX.XT”: Set the frequency of PWM1 to XX.X KHZ (00.1~99.9)

“S1F:X.X.X.T”: Set the frequency of PWM1 to XXX KHZ (0.0.1.~1.5.0.)

‘S1’: PWM1

‘S2’: PWM2

‘F’: frequency

‘D’: duty cycle

‘T’ is the end marker

2, set the duty cycle of the PWM

“S1DXXXT”: Set the duty ratio of PWM1 to XXX; (001~100)

“S2DXXXT”: Set the duty cycle of PWM2 to XXX; (001~100)

Set the success to return: DOWN;

Setting failed to return: FALL.

Serial Port Control:

Communication standard: 9600 bps

Data bits: 8

Stop position: 1

Check digit: none

Flow control: none

Application:

1. Used as a square wave signal generator to generate a square wave signal for experimental development;

2. Used to generate a square wave signal that drives the stepper motor driver;

3. Generate adjustable pulses for use by the MCU;

4. Generate adjustable pulses and control related circuits (applications such as PWM dimming speed regulation).

Package Included:

1 x Wave Signal Generator Stepper Motor Driver
