Features: Achieve precise control over your electronic projects with this 3 channel PWM signal module. Use this module in various applications such as LED dimming, motor control, and circuit testing. With its memory function and automatic exit feature, this module ensures convenient and efficient operation, making it an essential accessory for any development board. Restore production setting function: in dynamic setting modes, press and hold the UP and DOWN buttons at the same time to restore the production setting (after pressing, you need to power off and power on again, the data will be updated to the default data) Kinds of application scenarios: The module has a variety of control methods and working modes, and three output channels, which can meet the requirements of different environments. Specifications: Material:ABS Length:Approx.49mm/1.93in Working voltage: DC6-24V Working current: DC12-30MA 3independent buttons: used to set frequency, duty cycle, working status, etc.;Support long press, short press, simple operation and diverse functions. 3Channels PWM output: PWM Signal can set frequency and duty cycle respectively. PWM signal level: 5VTTL level PWM signal load capacity: <20mA Output frequency accuracy: 0.6% (10-30 Degrees Celsius) High frequency ranges: 20HZ ~ 1MHZ, duty cycle 0-100% Automatic exit function: If there is no operation for 36 seconds, the last set data will be automatically recorded, and the dynamic setting state will be exited. Real-time update function: Under the dynamic setting function, you can connect an oscilloscope to grasp the set frequency and duty cycle at any time, and output the precise frequency or duty cycle. Package Includes: 1xSignal Generator note: Please allow 1-2cm errors due to manual measurement,please make sure that you do not mind before you order.
