What is the difference between ESP32-wroom-32 and ESP- Wroom-32? Can they be used interchangeably?

Do you have links to the two? Those things aren't chips but modules btw.

Those are both different revisions of the same module; aside from potentially some RF changes there's not much difference between them. Be advised that you're likely to get a newer version of the module, however, as both modules were deprecated a fairly long time ago. As far as programming them goes, they're still exchangable (unless you use the GPIOs that are occupied by flash; they are NC in newer versions)
