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. Once the setting is successfully completed, the PWM state will take effect immediately The frequency and duty cycle of the two PWMs can be set separately, which is especially convenient in various intelligent control systems The 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 20 mA Signal amplitude: equal to the input voltage Frequency accuracy: 0.3%-2% Ultra high frequency range: 1Hz-150KHz Power off memory function: Exit dynamic mode, the parameters will be saved permanently Application scenarios: multiple control methods and working modes PWM Frequency: Setting range 1HZ-150KHZ 123: 123 Hz 023:23hz 12.3: 12.3 Khz 1.23: 1.23Khz 123.: 123Khz 0.23: 0.23Khz 0: The corresponding PWM keeps the level low 100: The corresponding PWM maintains a 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
