MicroMod Single-Pair Ethernet Function Board

SparkFun's COM-19038 MicroMod single-pair Ethernet function board introduces the ADIN1110 10BASE-T1L two-wire Ethernet protocol into the SparkFun MicroMod ecosystem. Using the ADIN1110 Ethernet transceiver from Analog Devices Inc., this function board provides a development tool for long-range, 10 Mb/s single-pair 10BASE-T1L Ethernet applications.

The SparkFun MicroMod single-pair Ethernet function board features a Harting T1 industrial single-pair Ethernet connector and passive components from Würth Elektronik, all populated on a MicroMod function board that can easily be added to the MicroMod system via its M.2 connector, which is plug-and-play, no soldering required.

The ADIN1110 is an ultra-low-power, single-port, two-wire Ethernet transceiver. It features an integrated media access control (MAC) interface to allow direct connections with a host controller via a serial peripheral interface (SPI) at 10 Mbp/s full-duplex. The specified cable reach for edge nodes is up to 1,700 meters.

The 10BASE-T1L Ethernet uses a single twisted pair for data and power. This function board is not designed to provide power over the cable. It is intended for long distance connections with reduced cable weight and increased connector integrity for edge node devices in applications such as industrial installations and field instruments. The 10BASE-T1L Ethernet is compatible with the 802.3cg IEEE® standard, supports high bandwidth up to 10 Mb/s, and sends and receives data on Ethernet connections over 1 kilometer long.
