What Module Can I Use to Measure DC Voltages Up to 40V, or Should I Build a Voltage Divider?

Hello, all.

I am doing a project in which I need to measure DC voltage up to 40V. I know that I could do a simple voltmeter using 2 resistors and a capacitor. However, I was looking to buy one module that could measure the voltage of this circuit since I am not experienced in this field. Do you know any type of product that can measure dc voltages up to 40 V. I have found the ZMPT101B but that is suited for AC. Or do you advise me to build a divider?

Thanks.
