Wanted: sub-$10 *networked* boards

morgaine
morgaine over 11 years ago

The early part of this decade witnessed the rise of a new commercial phenomenon, the bringing to market of many sub-$10 evaluation, prototyping and hobbyist boards.  Although the terminology and market positioning has varied depending on the company, they're really all the same thing --- boards for enthusiasts, which serve the purposes of industrial evaluation equally well and also play a valuable company PR and device promotion role.  It's all one category really, and it's very sensible to roll these diverse purposes into one because of economies of scale, inventory reduction, and audience synergy.

 

Probably the greatest mindshare in this $10 (ballpark) area has been obtained by three companies so far:

 

  • Freescale with its Freedom boards FRDM-KL25Z and FRDM-KL46Z, featuring low-power Cortex-M0+.
  • ST with its STM32Fx-Discovery range, often given away free, featuring high performance Cortex-M4.
  • TI with its LaunchPad ranges, covering MSP430 (low power), C2000 (DSP), and Tiva/Hercules (ARM).

 

These devices are all, to summarize the $10 scene in a word, awesome. image  And that's probably understating it.

 

However, there is something missing from this excellent picture.  It's a very important thing, and it's very bad that it is missing:  networking.  This new millennium was built on a solid foundation of networking created in the latter part of the preceding one.  IP networking has so permeated our civilization today that its absence is as inconceivable as life without the telephone would have been in the preceding decades.  And yet despite this, the above three pillars of awesomeness live on isolated islands of non-communication.

 

Yes I know, it's quite easy to integrate them into an IP network, either through USB-based NICs or wifi adapters or using a small I2C-connected Ethernet or wifi board, or even Bluetooth or NFC, or even using SLIP over RS232 from days gone by.  But that's not the point.  The point is that they are not inherently connected, and so they have to be brought in from the cold.  This is more regrettable than it appears at first glance for several reasons.  It's a barrier to instant networking, it costs a lot more (there's a dollar penalty owing to unnecessary overheads), networking is not directly supported in the otherwise-awesome board's software, the add-ons dilute the manufacturer's own device promotion, and to be blunt, it's just annoying and not forward-looking.

 

I would recommend to manufacturers in this $10 (ballpark) space that 2014 be their year for networking everything in sight.  There's even a marketing angle for it --- the Internet of Things has acquired quite a lot of meme-space recently, and it's always a better idea to ride a wave rather than to stand in its way.  Sub-$10 networked boards would be extraordinarily synergistic to the IoT concept --- it shouldn't surprise anyone if hundreds of millions of a single board are sold, because $10 falls wells under the price-worry radar in the West at least.  I suspect the main limitation on sales would be effectiveness of promotion/advertising producing awareness, and not the price.

 

Come on Freescale, ST and TI (strictly in alphabetical order), add networking into this extremely cost-constrained niche, even if it's only 10Mbps.  You can do it.  And the rest of you manufacturers, don't worry about the incumbents ruling the roost.  Word of mouth and reblogging is the primary form of advertising today (I'm even doing it right here), and if you provide the goods, we'll spread the interest.

    USB hardware is very cheap (no magnetics, low power) and usually present all but the cheapest SoCs, so why not do IP over USB directly without messing around with Ethernet?  With 10baseT and higher you need an Ethernet hub or switch anyway, and you could fairly easily make an IPoUSB bridge/router that has a bunch of USB host ports to connect to your devices plus an Ethernet up-link.  The b/router would perform the polling needed to see if devices have upstream IP packets.

     

    I thought something like this might be a nice way to network a classroom filled with RasPi Model A boards.

     

    I've heard lots of talk about the Internet of Digital Things (IDioT), but I haven't seen standards or chips for handling the 'torking (my first neologism for 2014, an abbreviation of "networking" based on its common Internet mis-spelling "newtorking").

    Regarding Internet of Things, stripping off all the frills and hype and decoration (we're pretty immune to hype anyway here, fingers crossed), it's just IPv6 on everything at extremely low cost through integration.  Viewed that way, IoT documentation is already 100%.  (IoT organizations typically push IoT middleware, but that's actually just decoration around what is no more than plain IP.)

     

    Note: IoT on IPv4 is just a wave to the past so that the poor old 98% of IP users don't feel too disenfranchised. image

     

    Note that my $10 goal doesn't come even close to embracing IoT in a proper way.  The aim should be sub-$1 if networking is to be omnipresent in everything that isn't by design isolated permanently.  (There are many extremely important applications where such isolation by design is important, indeed crucial, particularly in this post-Snowden era).  Sub-$1 IoT devices are perfectly possible even today, given that many microcontroller families have members that cost a fraction of a dollar.  But for 2014, I'm happy to aim towards just the relatively unambitious $10 niche.

     

    So, don't get hung up by IoT vendor machinations and nods to the past.  It's just highly integrated IPv6.

    Actually, I was thinking about IDioT layer 1, where there's been talk of ultra-low-power wireless networking, so that you can have IDioT devices that have very long battery lifetimes or preferably do energy harvesting (the 21st Century self-winding watch) so that they don't need batteries at all.

     

    Of course, if we're limiting networking only to devices that I personally want networked, then I'm already done!  I absolutely don't want my TV, my car, my bicycle, my furnace, my cats, my glasses, or my wristwatch networked to anything. image

    I know what you mean, but it's not "IoT layer 1", it's just layer 1 or the physical layer of networking, no different to Bluetooth or Wifi or, in wired, UTP Ethernet --- they all carry arbitrary higher protocols as payload.  Again, I'll stress that there's a lot of hype around in IoT, but if one rises above it then what's visible in practice is just IP riding on top of low-power physical layers like 6LoWPAN.  Ignore the rest.

     

    I do agree completely that the low-power physical layers are in their early days and require more and better documentation, and most important, community synergy.  Those that don't integrate into IP are doomed to failure, but conversely, those that integrate into IP are "doomed to simplicity" because they're just a layer 1 and hence work trivially or else disappear.  And they're all optional anyway --- if you have power or are wired then power-austerity is not usually essential.

     

    It's odd how supposed promoters sometimes work against their own interests by making things appear more complex than they really are.  IoT is a bit like that, but the decoration is superfluous, and when it comes to application processor boards with full stacks, the complication is not even present because *nix has everything it needs already built in.
