Operating Instructions:

PWM to Voltage:

💍 Upon powering the module, the output voltage will initially be 0V in the absence of an input signal. To establish a proper calibration, it is advisable to input a PWM signal with a 50% duty cycle and frequency between 1kHz and 3kHz. Connect this to the PWM and GND terminals. Utilize a multimeter to monitor the output voltage at VOUT, adjusting the onboard potentiometer until it accurately displays 5.00V. Subsequent changes in frequency may necessitate re-calibration to maintain accuracy.

🛠️ The output voltage can be manipulated by adjusting the duty cycle of the input PWM signal, and precision can be enhanced using the onboard potentiometer.

🛠️ To utilize the voltage to PWM conversion function, connect a suitable voltage to the VIN terminal, making sure to observe the correct polarity to prevent damage. The module accommodates two operating voltage ranges: 0-5V or 0-10V, depending on the selected mode. Adjusting the input voltage will modify the PWM duty cycle, with further precision achievable through the onboard potentiometer.
