Features Basic Specifications: This is a single-chip microcomputer that supports adjustable pulses, frequencies, and duty cycles. Large fluctuations due to external interference, such as wired or wireless, or high temperatures. Automatic conversion: if the converter module has no decimal point, the unit is HZ; if there is a decimal point, this is the unit of KHZ; automatic conversion without manual adjustment. Wide Application: This is a PWM, square and square wave signal generator, which can be used as an experimental development. The drive module can be applied to the motor driver square wave generator; as an adjustable pulse generator of the MCU. LED Digital Display: This drive module features a digital LED display with intuitive and clear readings. The frequency and the duty cycle are displayed more clearly. High precision detection. Automatic data saving: All parameters are automatically saved after setting and will not be lost in the event of a power failure. It is not necessary to set the data after a power failure. The button supports lock function to avoid misoperation. Specification: Item Type: Duty Cycle signal generator Model: YF-6 Frequency range: 1Hz ~ 100KHZ adjustable by the knob of the potentiometer Duty Cycle Range: 0~100% adjustable, set by potentiometer knob Power supply: DC 7V ~ 24V universal PWM width = input voltage Output PWM Drive Capability: The output is driven by the S8050 transistor driven Package list: 1 drive module Note: Note that the input voltage can only be 7-24V DC, and the power supply is not divided into positive and negative poles. Please avoid working in rainy and humid environment. Package List 1 x Drive Module
