Features: brand new and high quality This module is a module capable of converting voltage and PWM. The PWM digital signal is converted into 0 to 1OV analog signal. The output voltage is adjusted by the duty cycle of the entire PWM. V-PWM can convert 0-5V-10V voltage to 0%- PWM output, and adjust the PWM duty cycle by adjusting the voltage. Do not connect them in reverse to avoid damage to the board and devices. Package Includes: 1 x Voltage to PWM Converter Module Specifications: Module working voltage: DC 5V-12V Output PWM frequency: about 50KHZ PWM amplitude: 5V Conversion range: 0-5V/0-10V Voltage conversion: 0%-100%6PWM Tolerance: 1%-3% Pin description: Voltage to PWM: VCC: Working power supply 5V-12V. GND: working power ground VIN: input voltage 0-10V GND: Input signal negative terminal. GND: Output PWM ground. PWM: output PWM note: Instructions for use: Connect the working voltage to VCC and GND. Do not connect them in reverse to avoid damage to the board and devices. Connect a controllable voltage at the terminal. The voltage range is divided into two types: 0-5V and 0-1 0V according to the select mode. The PWM output is PWM. The duty cycle can be adjusted by adjusting the voltage. The accuracy can be controlled by adjusting the potentiometer
