I always find it hard to take things seriously when they are written in poor english. "Will coming soon" makes me worry about the quality of the rest of the project, maybe more than I should.

"I always find it hard to take things seriously when they are written in poor english."

You realize English should be capitalized, right?

This looks really awesome. I've been contemplating a KickStarter project for a Linux networking device for a while, and this may well make it possible at an attractive per-device price point. Everything else was either too pricey or not quite powerful enough.

Any electronics-related web page that uses "shield" other than as meaning "RF emission/reception blocking element" is automatically obnoxious, mobile or not.

it is a very common and well known term in the Arduino world, and the physical appearance of the device with all of the header pins would immediately suggest shield applications to anyone who has spent time with Arduino

Why is 'shield' more appealing than 'daughterboard' anyway? Gender neutrality?

I don't think networking is the market of this thing, despite the name. In fact, it could probably use a different name. It's a mips24k; I doubt it can do software networking at the 300mb speed the wifi runs at.

Do you have an idea how much of bandwidth a MIPS cpu like that can push? The chip is actually made for routers: it has 802.11n "MAC/BBP", 5-port 10/100 switch, etc. http://www.anz.ru/files/mediatek/MT7620_Datasheet.pdf I wonder how "Hardware NAT with IPv6 and 2 Gbps wired speed" works if the switch is only 100 Mbits... I guess if what you want out of this is really a router, you are supposed to either build the rest…

I looked into a lot of these boards a while back and most are like this one: crippled with 100mbps Ethernet. Sad to see that yes, this one is too. The Ethernet module is far slower than what the CPU can push.

Doesn't destroy it, but it's certainly a black mark. Are 1gig chipsets that much more expensive than 100mbps these days?

Thanks for pointing out, we corrected it. :)

If I can share a suggestion: the phrase "Born to be proud" comes off as a bit arrogant and doesn't sound natural to a native English speaker. If you're proud of the product, or you're trying to convey the idea that it was created with good intentions, some different wording might get your point across better. Something like "a better open platform" or "born to be open" [even though that also doesn't sound natural eit…

Made with pride is the most literal translation. I think the intent though is Born to be free however there is no good translation of that given the many meanings of free that even native speakers cannot understand ( https://en.wikipedia.org/wiki/Libre )

It's a chip for very low-end routers: 2.4GHz only, no gigabit switch (although apparently it can be equipped with two gigabit ports), and a CPU that would struggle to do 50Mbps WAN-LAN with firewall and QoS. It's only redeeming quality is that it apparently has a PCIe lane, but the CPU is still going to have trouble feeding whatever NIC you connect to that.

Is it open hardware if the ISA of the processor is not free (in both senses)? I think MIPS (which this uses) is free, but I see a lot of open hardware where I doubt the ISA, much less the architecture, is free.

Generally in the "maker" community open hardware is based on layout and software level openeness. So board layouts are shared even if the internals are not. This is what allows adruino to be open as they share layout files and software, but the Atmel AVR micro-controller they use does not have an open design. It does get confusing since there are open hardware projects that go down to silicon, but for the most part t…

The problem I often see with "open" devices like that is that they typically work with exactly one Linux kernel binary that shipped with the device. They usually don't work with upstream kernels.

Even if you can get original kernel source, it might not be trivial to get it to compile. Porting the required changes to a newer kernel once a security vulnerability was discovered can be very time consuming.
