Usually the fastest way to find a driver is to use the community-created wiki. There are two pages there that are set up for this.
The first is the table of edge Drivers. It’s very new, and quite incomplete, but the information that is there is good. It’s sortable, so you can sort by model number or by manufacturer.

If you don’t find your model there, then check the quick browse lists. These are organized by device class, so there’s one list for lighting, one for sensors, etc. This will take you to the author topic in this forum, where you can check the exact model numbers, see how other people are using it, find out about features, etc. doing it this way should take you directly to the information about the channel link and save you a lot of time compared to just googling.

I would also recommend that anyone new to edge drivers read the community FAQ as it explains how to install them, how to determine what you have already installed, official announcements, timelines, and additional helpful information.
