Beschreibung
Two-Wire ETH 3 Click is a compact add-on board designed for single-pair Ethernet connectivity in industrial and embedded systems, providing 10BASE-T1S communication over a single balanced pair of conductors for long-reach and noise-resilient networking. The board is based on the LAN8651B1 single-port 10BASE-T1S MAC-PHY Ethernet controller with SPI interface from Microchip, developed in compliance with IEEE 802.3cg and OPEN Alliance TC-6 specifications. By integrating both MAC and PHY in a single low-power device, the LAN8651B1 allows low-cost MCUs to directly access 10BASE-T1S networks via a high-speed SPI interface, supporting 10Mbit/s half-duplex communication, cut-through data transfer for reduced latency, and industrial-grade EMC and EMI compliance. A key feature of this Click board is the inclusion of an industrially isolated output stage using a WE-STST signal transformer (74930030) from Würth Elektronik, ensuring high galvanic isolation, long-distance signal integrity, and PoE capability. This Click board is ideally suited for industrial automation, factory networking, building automation, and other applications requiring robust, long-reach Ethernet communication over single-pair cabling.
