      I purchased several Atom S3 Lite for various projects.

      The Isolated RS485 Unit (SKU: U094) looks like the safest option, since it provides galvanic isolation between RS485 and the Atom S3 Lite.

      However, for a better mechanical integration, the ATOMIC RS485 Base (SKU: A131) would be more appropriate, as the Atom S3 Lite could simply plug in directly, without having to hang as a separate thing with a cable in the case of the SKU 094 / RS485 Unit.

      However, it seems to me that the ATOMIC RS485 Base is NOT isolated.

      Or am I missing something ?

        Hello @luckylinux

        correct, the Atomic RS485 Base is not isolated. See schematic here.

        Compared to Isolated RS485 Unit which uses the CA-IS3082W IC - schematic here.

        Thanks
