Model

Feature:
1. Scope Of Application: Used as square wave signal generator to generate square wave signals for experimental development and use to generate square wave signals for controlling motor drivers.
2. Generate Adjustable Pulses: This module generates adjustable pulses for MCU use and control related circuits (applications such as PWM dimming and speed regulation).
3. Easy To Operate: PWM output, this module can set the frequency and duty cycle separately, with wide frequency range and high accuracy.
4. LCD Display: The frequency and duty cycle of the LCD display are very clear. This module can communicate with serial port. All setting parameters are saved after power off.
5. Four Frequency Range, Automatic Switching: XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz, X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz, XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz, X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz.

Specification:
Item Type: Signal Generator Module
Material: Plastic
Frequency range is divided into four, automatic switching:
1.XXX (without decimal point): the smallest unit is 1Hz, in the range 1Hz ~ 999Hz;
2.X.XX (one hundred decimal point) is minimum unit 0.01Khz, ranging 1.00Khz ~ 9.99Khz;
3.XX.X (ten in decimal): minimum unit is 0.1kHz; range 10.0KHz ~ 99.9KHz
4.X.X.X (decimal in ten and one hundred): minimum unit is 1Khz; range 1KHz ~ 150KHz
e.g. frequency display: 100 indicates that the PWM output pulse of 100Hz;
1.01 represents the PWM output pulse 1.01K;
54.1 represents the PWM output pulse 54.1KHz;
1.2.4 indicates that the PWM output pulse of 124KHz;
Duty cycle range: 0 to 100%
All setup parameters, power down save.
Module Parameters:
Working Voltage: 3.3 ~ 30V
Frequency range: 1Hz ~ 150KHz
The frequency accuracy: in each range accuracy is about 2%
Load capacity signal: output current of about 5 ~ 30ma
The output amplitude: PWM amplitude equal to the supply voltage
Ambient temperature: -20 ~ + 70 ℃
The Serial Port Control (MCU TTL level communications)
Communication Standard: 9600 bps Data bits: 8
Stop Bits: 1
Parity Bit: None
Flow Control: None
1. The PWM frequency
"F101": Set the frequency of 101 HZ (001 ~ 999)
"F1.05": Set the frequency of 1.05 KHZ (1.00 ~ 9.99)
"F10.5": Set the frequency 10.5KHZ (10.0 ~ 99.9)
"F1.0.5": Set the frequency of 105KHZ (1.0.0 ~ 1.5.0)
2. The PWM duty ratio
"DXXX": Set the PWM duty cycle is XXX; (001 ~ 100)
For example D050, set the PWM duty ratio is 50%
3. Reads the set parameters
Send "read" string read parameter settings.
Setting successful return: DOWN;
Setting failback: FALL.
