Available from MikroElektronika, featuring the LAN8651, is the [**TWO-WIRE ETH CLICK - MIKROE-5543**](https://www.mikroe.com/two-wire-eth-click), a compact add-on board with the purpose of a generic interface to many microcontrollers in 10BASE-T1S applications.

The LAN8651 combines a Media Access Controller (MAC) and an Ethernet PHY to enable low‑cost microcontrollers, including those without an onboard MAC, to access 10BASE‑T1S networks. The common standard Serial Peripheral Interface (SPI) of the LAN8651 allows interfacing with nearly any microcontroller, so that the transfer of Ethernet packets and LAN8651 control/status commands are performed over a single, serial interface. SPI also requires only 4 pins, enabling a simpler hardware interface with fewer pins than MII or RMII.
