Questions about this item

Does the 3.3 V logic level create noticeable heat during continuous use?

The cable itself carries only low-current 3.3 V signals, so it generates no measurable heat.

What must my board provide for the female DuPont connectors to attach?

Your board needs a 4-pin header with 3.3 V logic so the female DuPont ends can plug directly onto it.
