Used to generate a square wave signal that drives a stepper motor driver.\r\n3. Generate adjustable pulses for use by the MCU.\r\n4. Generate adjustable pulses to control the associated circuitry.\r\n\r\nSpecification:\r\nWorking voltage: for DC 4-30V\r\nFrequency range: 1Hz~160KHz\r\nFrequency accuracy: 2%\r\nDuty cycle range: 0.00%-\r\nSignal load capacity: output current 5~30mA\r\nOperating temperature: -20℃~70℃\r\nMaterial: Plastic & metal\r\nDimensions: 45.2x25.8x15mm/1.78x1.02x0.59inch\r\nLED display color: Red + blue\r\nQuantity: 1 Set\r\nNote: 1.Please allow 0-1cm error due to manual measurement. pls make sure you do not mind before you bid.\r\n 2.Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you!\r\n\r\nPackage includes:\r\n1 Set Signal Generator\r\n\r\n\r\n\r\n\r\n----------------\r\nInstructions:\r\nThe single PWM generator has only one set of PWM1 outputs and the frequency and duty cycle are independently adjustable.\r\nTwo-way complementary PWM has two sets of PWM1 and PWM2 outputs. The two sets of frequencies have the same frequency and their duty cycles are complementary.\r\nAdjustable frequency 1-160KHz\r\nDuty cycle 0- adjustable\r\nOperating voltage: 4V~30V\r\nFrequency range: 1Hz~160KHz\r\nFrequency accuracy: 2%\r\nSignal load capacity: output current 5~30mA\r\nOutput amplitude: The amplitude is equal to the working voltage.\r\nPWM output, can set the frequency, duty cycle\r\nThe frequency is divided into four ranges, automatically switching:\r\n1.XXX (no decimal point): 1Hz~999Hz, unit 1Hz\r\n2.X.XX (decimal point in hundreds): Value is 1.00KHz to 9.99KHz in 0.01KHz\r\n3.XX.X (decimal point in ten digits): The value is 10.0KHz~99.9KHz, the unit is 0.1KHz\r\n4.X.X.X. (full decimal point): Value 100KHz~160KHz, unit 1KHz\r\nE.g:\r\n 100 represents 100Hz\r\n 1.00 means 1.00KHz\r\n 10.0 means 10KHz\r\n 1.0.0. Represents 100Khz\r\nDuty cycle 0~ adjustable\r\n \r\nSetting process:\r\n1. Press the SET button. The frequency parameter flashes. Set the frequency with the UP or DOWN button.\r\n2. Press the SET button. The duty cycle parameter flashes. Set the duty cycle by pressing the UP or DOWN keys.\r\n3. Press the SET button to exit the setting\r\n4. Long press the UP and DOWN keys to quickly increase or decrease\r\n5. The data is automatically memorized and all setting parameters are saved when power is off."]
