5pcs 2 Channel PWM Generator Module Pulse Frequency Duty Cycle Adjustable
- Description
1. Operating Voltage: 5-30V,support micro USB 5.0V power supply
2. Frequency Range: 1Hz~150KHz
3. Frequency Precision: 2%
4. Signal Load Capacity: output current is within 8--30mA
5. Output Range: default 5V V-pp (can be changed by external power)
6. Ambient Temperature: -30 Celsius ~70 Celsius
Application Fields:
1. As square wave generator to generate square wave for experiment development
2. Used to drive steeping motor driver's square wave
3. Generate adjustable pulse for MCU using
4. Generate adjustable pulse for controlling relative circuit (PWM adjust light speed etc)
Serial Port Control:
1. Communication Standard:9600 bps
2. Data Bit:8
3. Stop Bit:1
4. Verify Bit:none
5. Flow Control:none
Setting PWM Frequency:
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:
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
Parameter Setting:
Module has 3-channel key: Set, Up, Down
1.By short press SET key, can shift display 4 parameter values (FR1 :PWM1 frequency; dU1: PWM1 duty cycle; FR2: PWM2 frequency; dU2: PWM2 duty cycle); before shifting, there will be corresponding parameter name flashing.
2. Directly press UP, DOWN key to modify current parameter value
3. 2-chhannel PWM are set 3 kinds frequency value, in frequency display interface, by long press SET to shift, 3 kinds frequency's duty cycle are the same (XXX:1Hz~999Hz; XX.X:0.1Khz~99.9Khz;X.X.X.:1Khz~150Khz)
