Description:OOTDTY Feature:LCD liquid crystal display frequency and duty cycle, very clear, PWM output. Wide frequency range and high accuracy. The module has 4 independent buttons for setting the frequency and duty cycle. It supports short press (increase or decrease unit) and long press (fast increase or decrease). It's very simple. After setting the parameters, it is automatically saved when the power is turned off. The frequency is divided into four ranges, which are automatically switched:1.XXX (without decimal point): the minimum unit is 1Hz, and the value range is 1Hz-999Hz;2. The minimum unit of X.XX (the decimal point is in the hundreds) is 0.01Khz, the value range is 1.00Khz-9.99Khz;3.X X.X (the decimal point is in the tenth place): the smallest unit is 0.1Khz; The value range is 10.0KHz-99.9KHz;4.X.X.X (the decimal point is in the tenth and hundredth): the smallest unit is 1Khz; The value range is 1KHz-150KHz.Specifications:Item Type: Signal Generator Module Material: Electronic Components Size: 32x5 2mm/1.2x2.04in Color: BlueFrequency: 1Hz-150Khz (Adjustable)Duty Cycle Value Range: 0-Working Voltage: 3.3-30VDfrequency Accuracy: the accuracy in each range is about 2%Signal Carrying Capacity: the output current can be about 5-30maOutput Amplitude: the PWM amplitude is equal to the supply voltageAmbient Temperature: -20-70°BODYnmość: 1PCCres Applications:1.
