Features 3 independent buttons are used to set frequency, duty cycle, working status, etc Support short press plus 1 or minus 1, long press (fast increase or decrease) simple operation The UART communication interface sends commands to achieve the same function as the button. After the setting is successful, the PWM status will take effect immediately Frequency and duty cycle of the two PWMs can be set separately, which is particularly convenient in various intelligent control systems Working modes are divided into normal mode, dynamic mode, and UART serial port mode Specification: Item Type: PWM Generator Independent Buttons: 3 UART Communication Interface: Send Commands Two PWM Outputs: Set Frequency and Duty Cycle Signal Load Capacity: About 20mA Signal Amplitude: Same as Input Voltage Frequency Accuracy: 0.3%-2% Ultra-High Frequency Range: 1Hz-150KHz Power-off Memory Function: Exit the dynamic mode, the parameters will be permanently saved Application Scenarios: Multiple control methods and working modes PWM Frequency: Setting range 1HZ-150KHZ 123: 123hz 023: 23hz 12.3: 12.3Khz 1.23: 1.23Khz 123.: 123Khz 0.23: 0.23Khz 0: The corresponding PWM keeps low level 100: The corresponding PWM keeps high level 1-99: The corresponding PWM duty cycle is 0.01-0.99 Package List: 1 x Motor Drive Module Package List 1 x Motor Drive Module
