The only thing is it doesn't address a new or existing market as-is because it competes with what already exists. For example, a TrendNet 10/100 compact switch (not a hub) goes for $7.31 including shipping on eBay and it comes with a case and a power supply. Decommodifying a product requires finding niches where there is demand like automotive, aerospace, military, or marine applications. Until roughly 2020, 2.88 MB 3.5" floppy drives were in-use primarily in industrial and turnkey commercial systems long after they disappeared from desktop computers. Dinosaur technologies can live on for a very long time, often in critical systems deemed too expensive to replace.
Keep pushing forward, learning, and getting better.
Btw, if someone made a:
- 48 port 10GBASE-T (802.3an-2006) POE++ (IEEE 802.3bt-2018) 960W-1600W+ (3422W would be the upper limit for type 4)
- L2 (at least) switch
- unmanaged to fully-managed (but no cloud features)
- 4 100GBASE QSFP28 uplinks (unpopulated)
- dual, hot-swappable PSUs
- 2 models: Ports facing either forward or reverse
- 19" 1U half rack depth, and wall mountable
- Most importantly: doesn't sound like a jet engine under full load by leveraging better engineering, such as using some industrial-rated parts, heatpipes, and moving hotter air but less volume
I'd throw down in the $6K price-point neighborhood.
Comparables:
$4800 FS S5860-48XMG-U is close but sounds like a jet engine with dual 1U screaming PSUs and 3 hot swap chassis fans, but only available in conventional top-of-rack forward facing, leading to longer, messier wire management unnecessarily.
For those of us not generally in the hardware world (and thus not 100% familiar with the terminology) could you post more pics?
Especially of the enclosure? I'm not really sure if you are just exposing headers, or if there are regular Ethernet plugs on the board?
> probably for $10+shipping
You could honestly sell it for $30-40 and it would still be a pretty good deal. Meanwhile Blue Robotics be like "that'll be $175 plus $50 shipping and customs fees as a percentage of that $175 fam"

God, everything they sell is overpriced to the point of insanity. They could really use some proper competition.
I think it's been rightly pointed out that you aren't beating commodity parts on price, but you're also not a manufacturing operation with scale and there is a certain niche for which anything with open hardware that's well-documented is a killer feature
FYI: Phillips Exeter Academy is an elite, private high school in the United States. Mark Zuckerberg went there, too.
On the higher speeds, it remains difficult: In the datacenter, 10G ethernet is often standard or even outdated. But for non-mains powered systems, even 10G uplink is hard to come by. I would love to have a switch with 25/100G uplinks in a smaller-than-19"-rack form factor with 12-40V DC power. Building one as a side project might still be too complex - if you would get access to chipsets at all.
I bought a stack of these:
https://www.amazon.com/Tenda-Gigabit-Unmanaged-Wall-Mount-Pr...
for some projects that need ethernet. They are mid-level quality. Not sure I'd put them on something that would break my heart to get back.
That this switch is small and light might make for some interesting UAV applications as well!
Is creating bespoke parts a requirement for your robotics competition or just a part of your team's ethos?
PS. Try to reference vendor application notes or datasheets instead of stackexchange where possible.
Man, that's some serious inside baseball right there.
monoprice #41710 is $10 all in with a price break starting at qty 2.
maybe you want to qualify your description with 'embeddable'.

interesting b/c the website says `external magnetics`
A few months ago I wanted to make a small lab out of a few SBCs. Looking for a cheap 10/100 switch, I was surprised to see prices are this low; got a tplink 8 port / LS1008 for 10$ from Amazon.
Somewhere like http://tindie.com?
- Does the backplane support full 1.25Gbps throughput?
- Does is switch at line rate for all packet size?
- The switch chip supports LACP, port mirroring, vlan tagging, QOS, these would be amazing to integrate into a product even for slightly higher cost in a 5 port switch
- It's generally a hard requirement for me the 801.3az be off by default or can be turned off. I've had far too many issue with it enabled on network
Is this designed for personal or industrial use?

An Ethernet switch for $6.9 directly from JLCPCB is pretty incredible, thank you for making this product sector a tiny bit better :)
