SparkFun has launched a brand new entry in its MicroMod household, aimed toward those that need to experiment with long-distance wired communication utilizing the 10BASE-T1L Two-Wire Ethernet normal: the MicroMod Single Pair Ethernet Equipment.
“The SparkFun MicroMod Single Pair Ethernet Equipment demonstrates 10BASE-T1L Two-Wire Ethernet protocol inside the SparkFun MicroMod ecosystem through the use of two SparkFun MicroMod Single Pair Ethernet Perform Boards,” SparkFun’s Chris McCarty writes of the brand new bundle, “together with all of the equipment to run a proof of idea instance over 0.5 meters [around 1.6 feet] of cable, which will be useful earlier than putting in software nodes 1,700 meters [around 5,600 feet] aside to watch distant gear.”
Single-pair Ethernet, because the identify implies, runs on a only a single two-wire pair of an Ethernet cable. Developed for industrial and automotive communications, the usual permits for wired connections to succeed in effectively over a kilometer (round 0.6 miles) — albeit at 10Mbps, relatively than the sooner throughput of recent multi-pair Ethernet.
Designed as an almost-all-in-one equipment for single-pair Ethernet experiments, SparkFun’s newest MicroMod bundle contains two MicroMod Important Boards and a matched pair of MicroMod Single Pair Ethernet Perform Boards based mostly across the Analog Units ADIN1110 10BASE-T1L transceiver. Whereas there’s an Ethernet cable within the bundle too, there’s a few items lacking: the MicroMod Processor Boards, that are left as much as the person to select from a variety together with Espressif ESP32 and Raspberry Pi RP2040 variations.

There are a few different caveats to notice, too. The primary is a query of energy: the single-pair Ethernet normal permits for each information and energy to be carried throughout the cable to distant gadgets, however within the case of this bundle every MicroMod Important Board must be powered individually because the connection is data-only. The opposite is that the community cable is terminated for an industrial connector which, SparkFun warns, “is now not the principle medium for Ethernet of the 10BASE-T1L selection.”
The bundle is now accessible on the SparkFun retailer at $89.95 earlier than quantity reductions, with MicroMod Processor Boards beginning at $12.95.
