Impressive work from a high school team

Awesome work! It's really cool to see this from a high school team. While designing liquid rocket avionics [1] at Purdue Space Program, we went with a BotBlox switch that cost…

ChuckMcM on HNCongratulations! Impressive work for any age. Is creating bespoke parts a requirement for your robotics competition or just a part of your team's ethos?

Useful form factor for robotics and embedded systems
From 2 comments
This isn't a desktop Ethernet switch. Lots of robotic parts like industrial cameras and fancy laser sensors use Ethernet for interfacing instead of USB or RS232C. Doing so solves…

Objections
Only 100Mbps, not gigabit
From 2 comments
Worth noting though that the switch you linked claims to be a gigabit switch while the switch from murex is 100Mbpbs. Not sure if that justified the price difference
znpy on HNNice work indeed. However, was there a reason you didn't support gigabit ethernet? I haven't used 100mbit ethernet for more than a decade...

Not actually cheaper than commodity switches and enclosures
From 2 comments
Nice project and good work. 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…
banish-m4 on HNhmm ... not the cheapest. $7 is just for the PCB (assembly) right? you need an enclosure and power supply as well. monoprice #41710 is $10 all in with a price break starting at…

Claim of world's smallest questioned against BotBlox size
From 1 comment
The comparable BotBlox SwitchBlox Nano is 25.50 x 25.50 mm, albeit with two fewer ports. This is 44.90 x 42.11 mm. How do you justify the claim of being the world's smallest?

Blammar on HNCan you make a 2.5g version
tgtweak on HNCan you produce a 10Gb version of the same?

Nice job guys. For your next challenge, see if you can find a cost-effective way to add VLAN management, or do something cute with the form factor, like make it fit inside a…

Questions
Are board layout files available
From 1 comment
Very cool. It says fully open source, are the board layout files available?

Does it use auto-MDIX
From 1 comment
Sorry if I missed it on the page but are all the ports Auto-MDIX?

Why 100Mbps instead of single-pair Ethernet
From 1 comment
Why classic full-fat fast-ethernet (base-tx) instead of single-pair ethernet (base-t1 or t1l/t1s) if you are targeting embedded use?
