Features:brand new and high qualityThis 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. Specifications:Module working voltage: DC 5V-12VOutput PWM frequency: about 50KHZPWM amplitude: 5VConversion range: 0-5V/0-10VVoltage conversion: 0%-100%6PWMTolerance: 1%-3%Pin description:Voltage to PWM:VCC: Working power supply 5V-12V.GND: working power groundVIN: input voltage 0-10VGND: 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 Package includes:1 x Voltage to PWM Converter Module
