  • What is SPEBlox?

    SPEBlox is the world's first Gigabit (1000BASE-T) to Single Pair Ethernet (1000BASE-T1) converter in a tiny (38mm x 38mm) form factor, designed for direct integration into space-constrained networks.

    It functions as a transparent bridge between standard gigabit ethernet networks and single pair ethernet networks, working out the box without any software configuration. In other words, Standard GigaBit ethernet on one side (8 wires), GigaBit Single Pair ethernet on the other side (2 wires).


    Why use Single Pair Ethernet?

    You can cut down your cabling by a factor of 4 while still achieving gigabit ethernet rates. The implications of this are massive in space-constrained networking applications like drones and robots.
    An engineer's guide to single-pair Ethernet

    SPEBlox can be used to upgrade a standard gigabit network into a single pair ethernet network to achieve a 4x reduction in the cabling needed. The board comes preloaded with all firmware to make it work, meaning there only configuration you need to do is flip a switch on each board (one board must be master and the other board must be slave). That's it.

    Single Pair Ethernet is a very new technology that has not yet achieved significant market penetration. At BotBlox, we intend to change that; the benefits are just too great.


    This board is just our first product to make use of Single Pair Ethernet. We will be developing more boards in the future to further make use of this amazing technology.

    Why use SPEBlox?

    The main purpose of this board is to help our customers build proof-of-concept systems using Single Pair Ethernet. Think of SPEBlox as a development board that also happens to be directly integrateable into your product. 

    Simply drop the board into your system to replace bulky 4 pair connections and test your system!



    SPEBlox also allows you to test PoDL (Power over Data Line) which allows voltage to be transmitted along with data. This feature is still in testing.

    Why is the price so high?

    The short answer? Chip shortages. We're not joking when we say that the cost of one of the chips we use, usually priced at $4, has been jacked up to $105! As a result, we've had to massively increase the cost to match that cost. 

    Don't worry though, this price hike is only temporary and will come back down once the foundries catch up with demand, likely in Q2 2022. 

    We know the cost of this board is inflated, but we'd much rather offer an innovative product sooner at a higher cost and allow our customers to get their hands on the newer technology as soon as possible!

    So what will the price be in the future?

    Most likely between $45 to $100, TBD of course.


    Pre-ordering and delivery

    We're only doing a limited initial run on these first boards, so you should definitely place a pre-order asap if you're keen. 

    As a pre-order, you're entitled to a full refund before the product ships. Also, as we are making some changes to the board advertised in the product image, we'll extend that full refund for up to two weeks after you receive the board. 

    The expected shipping date for this board is 25 September 2021.
