PWM Generator 2‑Channel Frequency Module Adjustable Drive Electronic Component☜

Feature: \n 1. 3 independent buttons are used to set frequency, duty cycle, working status, etc\n2. Support short press plus 1 or minus 1, long press (fast increase or decrease) simple operation\n3. 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\n4. Frequency and duty cycle of the two PWMs can be set separately, which is particularly convenient in various intelligent control systems\n5. Working modes are divided into normal mode, dynamic mode, and UART serial port mode \n\nSpecification: \n\nItem Type: PWM Generator\nIndependent Buttons: 3\nUART Communication Interface: Send Commands\nTwo PWM Outputs: Set Frequency and Duty Cycle\nSignal Load Capacity: About 20mA\nSignal Amplitude: Same as Input Voltage\nFrequency Accuracy: 0.3%-2%\nUltra-High Frequency Range: 1Hz-150KHz\nPower-off Memory Function: Exit the dynamic mode, the parameters will be permanently saved\nA:
