Description

This is a mini digital square waveform generator module supporting 1Hz-150KHz frequency and 0%-100% duty cycle adjustment through the on-board momentary push button and also support external seial communication. DC 5V-30V wide voltage input and dual channel complementary output with red LED display the parameter ideal as the square wave source for instrument testing or driving the stepper motor and so on.

Package Included:
1X Digital 2 Channel Square Wave Pulse Signal Generator Module 1Hz-150KHz 0%-100%

Display Instructions:
There are 3 display range:
1:XXXX->the unit is 1Hz, range is 1Hz-999Hz
2.XX.X->the unit is 0.1KHz,range is 0.1KHz-99.9KHz
3.X.X.X.->the unit is 1KHz, range is 1KHz-150KHz
e.g.:100->100Hz;54.1->54.1KHz;1.2.4.->12KHz

Setting Instructions:
1. Short press"Set" to interchange display the 4 values(FR1:PWM1 frequency;dU1:PWM1 duty cycle;FR2:PWM2 frequency;dU2:PWM2 duty cycle)
2. press"Up" and "Down" to set the current value

Serial Control:
Baud Rage: 9600pbs; Date Bit:8; Stop Bit:1;
1. Set the PWM frequency:"S1FXXXT":set the PWM1 frequency as XXX HZ(0001-999);"S1FXX.XT":set the PWM1 frequency as XXX KHZ(00.1-99.9); "S1FX.X.X.T":set the PWM1 frequency as XXX KHZ(0.0.1.-1.5.0.)(S1->PWM1;s2->PWM2;F->frequency;D->duty cycle;T->Stop bit)
2.Set the PWM duty cycle:"S1DXXXT":set the PWM1 duty cycle as XXX(001-100);"S2DXXXT":set the PWM2 duty cycle as XXX(001-100)
3.DOWN:set successful;FALL:set fail.
