The SparkFun MicroMod Single Pair Ethernet Function Board brings 10BASE-T1L two-wire Ethernet to the MicroMod ecosystem using the Analog Devices ADIN1110 transceiver. It enables long-range, 10Mbps full-duplex Ethernet communication over a single twisted pair with cable reaches up to 1.7km.

The ADIN1110 is an ultra-low power transceiver with an integrated MAC that connects to the host processor via SPI. Compliant with the IEEE 802.3cg-2019 standard, 10BASE-T1L is designed for industrial installations and field instruments where reduced cable weight and long-distance connectivity are essential.
