3D of a 3-port RS485 GW. This actually have 5 RS485 (or RS-X). 2 on the backbone bus running high speed, and 3 isolated with lower speeds in front. These can be used Standard RS485, RSX or even Profibus/485.
The MCU is actually capable of running 3 port Profibus using UART’s saving the need for specialised hardware.
This module do not have the Raspberry PI Zero W add-on option. The reason is because the connector would conflict with the isolation area.
