SparkFun MicroMod Single Pair Ethernet Kit

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 can be used with an example based on two nodes. A MicroMod Single Main Board with a MicroMod Artemis processor and a MicroMod Single Main Board with a MicroMod ESP32 Processor processor. These two Main boards should be connected with the included 0.5 meter Industrial Ethernet Cable.

Note: This kit includes the required hardware to provide proof of concept communication over 10BASE-T1L Ethernet. A Qwiic sensor should also need to be integrated into your system depending on your monitoring application. These parts will need to be purchased separately.

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!

Core Skill: DIY

Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.

1 DIY

Skill Level: Noob - Basic assembly is required. You may need to provide your own basic tools like a screwdriver, hammer or scissors. Power tools or custom parts are not required. Instructions will be included and easy to follow. Sewing may be required, but only with included patterns.
See all skill levels

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

3 Programming

Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

    Is the code base used in the Sparkfun demo during the SPE webinar available ? Unlike what is in the SparkFun SPE kit (that includes two main board - Singles), your demo show cased a regular ethernet function board and a SPE function board installed in the same MicroMod main board - Double, that was interacting with a MicroMod main board - Single. It is unclear how useful SPE is without regular ol' ethernet in the mix too. Thank you.

    Question: Is there support for broadcasting messages to multiple recipients or multicasting like UDP?

    What is the underlying protocol? Is it plain ethernet? Or is it TCP? .. Does it has a way or expectation of message acknowledgment or a sequence of arrival expectation?

    Thanks for the help

      This is a pretty well written overview of the specification. There are differences from standard TCP/IP.

      Basically, yes, SPE allows you to do these things, but it might not default to this solution.

      There’s not a lot of compute power required in the device for SPE. It can operate with TCP/IP or UDP stacks. In fact, there are some technical papers presented by ODVA in a category called “constrained devices” on the ability of SPE operating with UDP.

        Thank you for the info.

        How would you connect a regular computer or a raspi to a spe network? Is there any tutorials you can point me to?

        Are there any hubs available easily?

        Any support for other dual spe chips for arduino libraries?

        Sorry for all questions but I can’t seem to find clear info out there.
