Isolated 10BASE-T1S Industrial Ethernet HAT++ for Raspberry Pi
In Production
10BASE-T1S (IEEE 802.3cg) enables 10 Mbit/s Ethernet communication over a single twisted pair in multidrop topologies, supporting at least 8 nodes over distances of up to at least 25 m.
This HAT enables multidrop communication based on 10BASE-T1S Ethernet using the Microchip LAN8651 Ethernet MAC-PHY and, as part of the BE-IIS HAT++ ecosystem, is stackable with other HATs from the portfolio for seamless system expansion and simplified system integration.
