Digital display for voltage

[sgtdisturbed47]

I'm looking to take the next step with my mods. I've been favoring 5v for quite some time, but I'd like to go variable so I don't destroy sensitive liquids. I'm going to mainly use 4-6 volts, but I'd like to use a digital readout for voltage under load. I'm sure I could use one of the displays that madvapes sells, but those look to be preassembled. Do you fine modders have a preference for a particular display?

Get the meter itself and put in in the box you like

Ebay has them as well as multiple color displays so whatever is your preference is the way to go
