Following up on our last Great Search for a DMX / XLR connector, our next step is to find a DMX transceiver. We started by looking at official and common DMX shields for Arduino since we know there's a ton out there, including the semi-official TinkerKit brand (https://web.archive.org/web/20140727121929/http://www.tinkerkit.com/dmx-master-shield/).

These boards all use the MAX485 (https://www.digikey.com/short/q7mbb9bj) and XLR connectors. They often *don't* have isolation or transient voltage protection. While the MAX485 is readily available, let's look at some other options that might work out for our design, especially if they have isolation built in!
