2-Channel 5V PWM Pulse / Square Wave Generator Module 1Hz-150KHz Frequency US

Description

2-Channel 5V PWM Pulse Square Wave Generator Module 1Hz-150KHz Frequency
This economical 2-channel PWM pulse / square wave generator provides two pulse / square wave outputs with independent control over each channel's duty cycle and frequency using the straightforward LED display and set/up/down buttons. It can also be programmed through its serial RS-232 interface.
Applications for the module include:
A square wave generator to generate square wave signals for experimentation and control
Driving stepper motors
Generating adjustable pulses for microcontroller use
Generating adjustable pulses for PWM control of lighting and LEDs
Features and Specifications:
Frequency and duty cycle for each channel can be set individually
Operating Voltage: 5-30V, supports MicroUSB 5V input power
Frequency Range: 1Hz - 150KHz
Frequency Precision: 2%
Output Signal Capacity: Up to 30mA output current
Output Voltage: Same as input voltage, or can be independently varied from 5V to 30V with an external power supply input
Frequency and duty cycle settings are saved when the module is powered off
Dimensions: 44mm x 29mm x 9mm (LxWxH)
Ambient Operating Temperature: -30℃ to 70℃
Operating Parameter Settings:
The module has 3 control buttons: Set, Up, and Down
Short pressing the SET key will step the display through the 4 operating parameter values:
FR1: PWM1 frequency
dU1: PWM1 duty cycle
FR2: PWM2 frequency
dU2: PWM2 duty cycle
When each parameter is selected by pressing the SET button, the parameter name will flash before displaying the value.
After the parameter is selected, press the
UP and DOWN
buttons to modify the parameter's value.
Duty
cycle can be set from 1% to 100% in 1% increments.
The frequency range can be selected before entering the value by long-pressing the SET button (approximately 1 second or longer):
XXX Display (Default): Frequency values from 1Hz - 999Hz frequency range
XX.X Display (1 long press of the SET button):
0.1Khz - 99.9Khz frequency range (i.e. 01.2 = 1.2KHz, 55.5 = 55.5KHz)
X.X.X.
Display (2 long presses of the SET button)
:1Khz~150Khz frequency range (i.e. 0.3.5. = 3.5KHz, 1.0.0. = 100KHz)
Serial Port RS-232 Control:
Communication Standard: 9600 bps
Data Bit: 8
Stop Bit: 1
Verify Bit: None
Flow Control: None
Setting PWM Frequency via the Serial Port:
1."S1FXXXT":set PWM1 frequency as XXX HZ (001~999)
2."S1FXX.XT":set PWM1 frequency as XX.X KHZ (00.1~99.9)
3."S1F:X.X.X.T":set PWM1 frequency as XXX KHZ (0.0.1.~1.5.0.)
4."S1": PWM1
5."S2": PWM2
6."F": Frequency
7."D": Duty cycle
8."T": Stop sign bit
Setting PWM Duty Cycle via the Serial Port:
1."S1DXXXT":set PWM1 duty cycle as XXX；(001~100)
2."S2DXXXT":set PWM2 duty cycle as XXX；(001~100)
Setting successfully back: DOWN
Setting unsuccessfully back: FALL
