2Channel PWM Signal Generator Pulse Frequency Duty Cycle Adjustable

Product DescriptionFeatures:  Two independent PWM outputs, can set frequency, duty cycle separately The frequency is divided into three ranges-XXX(No decimal point): The minimum unit is 1Hz, and the value range is from 1Hz to 999Hz-XX.X: The minimum unit is 0.1Khz, and the value range is from 0.1KHz~99.9KHz-X.X.X.: The minimum unit is 1Khz, and the value range is from 1KHz~150KHz-Duty cycle value range: 0 ~ 100-Three frequency ranges share a duty cycle, all setting parameters are saved when the power is off. Suitable for serial communication.Module Parameters: Working voltage: 5–30V, support micro USB 5.0V power supply. Frequency range: 1Hz – 150KHz. Frequency accuracy: ± 2%. Output current: 8-30mA. Output amplitude: Default 5V V-pp (settable). Operating temperature range: -30 ~ + 70 ℃.Parameter Settings: Three buttons: [Set], [Up], [Down]. Press [Set] key to switch the display of four parameters (FR1: PWM1 frequency; dU1: PWM1 duty cycle; FR2: frequency of PWM2; dU2: PWM2 duty cycle), before switching, there will be corresponding flashing of parameter name. 3. Press [Up], [Down] keys to modify the current parameter value (long press can quickly add or reduce). 4. Two PWM each have three preset frequency, and in the frequency display interface, long press [SET] key to switch between three types of frequencies, three kinds of frequency duty cycle is the same. (XXX: range 1Hz – 999Hz; XX.X: range 0.1Khz – 99.9Khz; X.X.X.: range 1Khz 150Khz,).Scope of application: To generate a square wave signal for experiment and development as a square wave signal generator To generate a square wave signal for stepping motor driver To generate adjustable pulse for MCU To generate variable pulse signal for controlling related circuit  Package including: 1pcs 2 Channel PWM Signal Generator Pulse Frequency Duty Cycle Adjustable for Motor Drive
