Signal Generator PWM Pulse Frequency Duty Cycle Adjustable Module LCD Display 1Hz-150Khz 3.3V-30V PWM Board Module

Module highlights
1. Three-way PWM output, adjustable frequency, three-way frequency output, duty cycle can be adjusted independently, suitable for most occasions;
2. LCD liquid crystal display frequency and duty cycle, very clear, very easy to adjust
3. Wide frequency range and high accuracy;
4. Serial communication

Module Description
3-way PWM output, wide frequency range, duty cycle can be adjusted independently in real time;

The frequency is divided into four ranges, automatically switching:
1.XXX (no decimal point): The minimum unit is 1Hz, the value range is 1Hz~999Hz;
2.X.XX (the decimal point is in the hundred place) is 0.01Khz, the value range is 1.00Khz~9.99Khz;
3.XX.X (decimal point in ten): The minimum unit is 0.1Khz; the value range is 10.0KHz~99.9KHz
4.X.X.X (decimal point in ten and hundreds): The minimum unit is 1Khz; the value range is 1KHz~150KHz

E.g. Frequency display: 100 represents the PWM output 100Hz pulse;

1.01 represents the PWM output 1.01K pulse;
54.1 indicates the PWM output 54.1KHz pulse;
1.2.4 indicates PWM output pulse of 124KHz;
Duty cycle values ​​range from 0 to 100%, where 100% is expressed in A%.
All setting parameters are saved after power off.

Parameter Settings
The module has 8 independent keys to set the frequency and duty cycle, support short press (increase or decrease a unit) and long press (fast increase or decrease), it is very simple, set parameters automatically save, power off is not Lost.
The 3-way duty-cycle button can be pressed at the same time, real-time adjustment, LCD display is the duty cycle of the last pressed button, real-time is very strong, can be used as a simple several-way duty cycle scan.

Module Parameters
1. Working voltage: 3.3~30V;
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 5~30ma;
5. Output amplitude: PWM amplitude and supply voltage are equal;
6. Ambient temperature: -20~+70°C.

The Scope Of Application
1. It is used as a square wave signal generator to generate square wave signals for experimental development and use;
2. Used to generate a square wave signal to control the motor driver;
3. Generate adjustable pulses for use by the MCU;
4. Generate adjustable pulses, control related circuits (PWM dimming speed control applications).

Serial Control (Single-chip TTL level communication)
Communication standard: 9600 bps
Data bit : 8
Stop bit :1
Check digit :none
Flow control :none

1. Set the PWM frequency
"F1.0.5": The setting frequency is 105KHZ (1.0.0~1.5.0)

2. Set the PWM duty cycle
"Dx:yyy": set the duty cycle of the PWM x: (1 ~ 3) PWM serial number, yyy: (000 ~ 100) duty cycle%;
For example, D1:050, set the 1st PWM duty cycle to 50%.

3. Read the setting parameters
Send "read" string to read the set parameters.
The read data format is as follows: F156, D1: 052, D2: 059, D3: 058,
Successfully set return: DOWN;
Failed to set return: FALL.

Package Included:
1 x Signal Generator PWM Pulse Frequency Adjustable Module LCD Display 3 Channels
Instructions/schematic are NOT included. We don't provide technical assistance please make sure that you are familiar with the product before purchasing.
