About Icstation PWM Frequency Meter 1Hz-150KHz DC
Icstation digital square waveform signal generator module supporting 1Hz-150KHz frequency and 0%-100% duty cycle adjustment through the on-board momentary push button and also support external serial communication. DC 3.3V-30V wide voltage input and blue back-light LCD display output frequency and duty cycle at the same time ideal as the square wave source for instrument testing or driving the stepper motor and so on. Specifications: Frequency Range: 1Hz-150KHzDuty Cycle Range: 0%-100% Accuracy: 2% Working Voltage: DC 3.3-30V Output Current: 5-30mAOutput Amplitude: the same as the power supply Module Size: 52X32mm/2.05X1.26inch(L*W)Package Included: 1 X Digital 2 Channel Square Wave Pulse Signal Generator Module 1Hz-150KHz 0%-100%, with independent antistatic packaging. 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 10.0KHz-99.9KHz 3.X.XX->the unit is 0.01KHz, range is 1KHz-9.99KHz e.g.: 100->100Hz; 54.1->54.1KHz; 1.2.4.->12KHz Serial Control: Baud Rage: 9600pbs; Date Bit: 8; Stop Bit: 1; Stop bit: 1; Check Bit: none; Flow control: none 1. Set the PWM frequency: "F101" set the frequency as 101Hz(001-999);"F1.05" set the frequency as 1.05KHz(1.00-9.99);"F10.5" set the frequency as 10.5KHz(10.0-99.9);"F1.0.5" set frequency as 105KHz(1.0.0-1.5.0) Set PWM duty cycle: "DXXX": set duty cycle as XXX;(001-100) Read setting: send "read" to read the set parameter, when set successfully, it will reply: DOWN; if failed, it will reply: FALL
