SparkFun MicroMod Single Pair Ethernet Kit

Added to your shopping cart

The SparkFun MicroMod Single Pair Ethernet Kit demonstrates 10BASE-T1L Two-Wire Ethernet protocol within the SparkFun MicroMod ecosystem by using two SparkFun MicroMod Single Pair Ethernet Function Boards and including all the accessories to run a proof of concept example over 0.5 meters of cable, which can be helpful before installing application nodes 1700 meters apart to monitor remote equipment.

The ADIN1110 is an ultra-low power, single-port Two-Wire Ethernet transceiver. It features an integrated media access control (MAC) interface to allow for direct connections with a host controller via a serial peripheral interface (SPI) at 10 Mbp/s full duplex. To top it off, the specified cable reach for edge nodes is up to 1700 meters.

10BASE-T1L Ethernet uses a single twisted pair for data and power (Note: this Function Board is not designed to provide power over the cable) intended for long-distance connections with reduced cable weight and increased connector integrity for edge node devices for applications such as industrial installations and field instruments. 10BASE-T1L Ethernet is compatible with the 802.3cg IEEE® standard, supports high bandwidth up to 10Mb/s, and can send and receive data on Ethernet connections over 1 kilometer long.

This kit is intended and includes the required hardware to provide proof of concept communication over 10BASE-T1L Ethernet. This connector type is no longer the main medium for Ethernet of the 10BASE-T1L variety.

Note: A MicroMod Processor board is not included with this kit and will need to be purchased separately for the parts included with this kit to function properly.


MicroMod is a modular interface ecosystem that connects a microcontroller “processor board” to various “carrier board” peripherals. Utilizing the M.2 standard, the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!

    Which MicroMod targets work with the Single Pair Ethernet Arduino library ? It seems RP2040 does not have Arduino support and ESP32 is not supported with the SparkFun ADIN1110 SPE library for Arduino.
