Problem Statement

I am using a 1200W DC-DC boost converter module (Input: 8–60V, Output: 12–83V, rated 20A). The module currently uses a manual potentiometer to adjust the output voltage.

My requirement is:

  • At startup, output should be fixed at 25V.
  • After that, I need to **automatically change the output voltage within the range 10V to 60V using Arduino (no manual potentiometer adjustment).
  • Output current requirement is up to 10A.
  • Voltage switching can be step-based or programmable sequence.
  • I need a stable and safe solution (with proper control, not mechanical servo turning the pot).

Questions:

  1. Can I replace the potentiometer with a digital potentiometer or DAC controlled by Arduino?
  2. Is there a better method to control output voltage programmatically?
  3. Are there any ready-made boost modules (10A range) that support digital voltage control (UART/I2C/analog control pin)?

Maybe.
Do you have a schenatic of this boost converter?

What's your plan to make it output 10V?

You can find quite affordable 10-60V BUCK converters with uart port.

Do you have any specific recommendations for reliable buck converters with digital control (UART/I²C) in the 10–60V range? We’re looking for something stable and accurate that allows programmatic voltage adjustment and monitoring.
Also, in your experience, is it better to use a ready-made digital buck module, or modify the feedback network of a conventional buck converter using a DAC/digital potentiometer?

I think you should describe what is exactly the purpose, more details you tell and better suggestions someone here can give..

Unless you are experienced with circuit design and have the schematic, I recomment you buy one that can be controlled via UART, I2C, ets
