- tormeh 12y agoIs 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.
- yasth 12y agoGenerally 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 that level of design is just beneath the concern of the people who want to internet enable their fridge or whatever. Just like most computers contain closed source code in the form of controllers and all but the most extreme open source types just don't care that they have a closed source USB controller.
- tormeh 12y agoWell, my beef with it is that the proprietary blobs should be interchangeable, and that requires an open ISA, the silicone can be as proprietary as it wants, as long as the interface is open.
- noselasd 12y agoThat would make any attempt at creating such a device very hard, if not futile, and not economical. The ISA is just a small part of what's required. All the other interfaces are just as important such as pinouts, memory mappings, memory interface, bus support and so on. There's very few SoCs from different vendors that are interchangeable even among the ones that uses an open ISA. This requires you to either build everyhing from scratch including the CPU, or to use more generic and perhaps interchangeable CPU or microcontrollers and rather push the special components to other chips instead of having those components on a SoC - which gains you nothing. Meaning the value of using an open ISA is miniscule as long as the code is available and easily translated to another ISA by a compiler.
- avian 12y agoThe 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.
- chrisBob 12y agoI 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.
- puzzlingcaptcha 12y agoFWIW, I have ordered some parts from Seeedstudio (including a Xadow board) and was quite satisfied with the service.
- nodata 12y agoSeeed isn't a typo, to save anyone else checking.
- Noel_lo 12y agoThanks for pointing out, we corrected it. :)
- chrisBob 12y agoIt looks good now. Next time I will try your support link instead, but I am glad you saw the comment and got it cleaned up. In the future it shouldn't be too hard to find someone willing to support and a good open source project with some proof-reading. I may not be the best candidate, but it would be a good way for someone to get started helping the project, and could make a big difference if you are targeting a larger audience.
- Noel_lo 12y agoThank you very much, It's very kind of you all if there's anyone like chrisBob mentioned who willing to help us with our poor English, pls mail me: noel@wrtnode.com, we could pay for it. :)
- peterwwillis 12y agoIf 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 either, unless you know what 'open hardware' is]. Here i've cleaned up some of the copy from your sales page: "WRTnode is a high performance, low power, small, inexpensive development board intended to run OpenWRT OS. It also easily ports open source software based on Linux. Today, more and more devices are connecting to The Internet of Things. The WRTnode is a small node which can connect to the internet all by itself and perform complex tasks, like detecting a cat running by, or identifying your speech and twittering it, or checking your email and speaking it to you, or learning how your room is laid out and finding garbage to sweep while streaming video to you over the internet. [..] Open Source hardware for OpenWrt [..] [remove the line "smart machines' heart"] complete set of high performance I/O [..] Local dns uses i.wrtno.de, wrtnode.lan, and openwrt.lan [..] default WRTnode ip 192.168.8.1 [..] WRTnode additional features (source at github.com/WRTnode):"
- peterwwillis 12y agoI hope this trend of really annoying scroll-skipping goes away like flashing "under construction" .gifs and framed pages.
- ris 12y agoAbsolutely. It's all very well and clever until you can't read all the text on the final page because it flows off the bottom.
- rffn 12y agoCould I have this please with 802.11ac WiFi, 5GHz, preferrably supporting a 4x4 MIMO setup. I would love to have an open access point for my network. I like to have more than 300Mbps and to avoid the 2.4GHz network though even more. I understand this owuld be more expensive, but would be willing to pay a higher price.
- sbierwagen 12y ago802.11ac WiFi, 5GHz, preferrably supporting a 4x4 MIMO Retail price just went up to $300. Four dual-band wifi radios are expensive.
- rffn 12y agoIf I could have a router or even just an AP with complete hardware documentation in public and 100% open source firmware for it that would be an ok price. With the advertised $25 of course greed kicked in as well. ;-)
- nargeogu 12y agoI'm curious to know why you want to "avoid the 2.4GHz network". Can you please explain why?
- michaelvanham 12y agoI can't speak for rffn, but many people want to avoid using the 2.4GHz spectrum due to congestion. In the 2.4GHz band there is a limited amount of space available, and there are now many wireless routers in typical residential neighbourhoods all competing for the same space. Many other devices such as cordless phones, baby monitors, and wireless speakers also use 2.4GHz and interfere with wifi signals. Most microwaves generate significant amounts of noise in the 2.4 GHz band when in use. In the 5GHz band there is much more space available, and there are many fewer competing devices and sources of interference. The penalty of 5GHz is slightly less range, and more expensive wifi equipment.

- guelo 12y agoWhat are the power specs? For battery powered applications like the shown mini-quadcopter you really need to know the watts as well as weight. Admittedly, WiFi has a very spiky power consumption profile.
- Noel_lo 12y agoCurrent consumption: 0.13A - same module, wifi off 0.17A - same module, wifi enabled 0.14A - dock (RJ45 included) + wifi off 0.20A - dock (RJ45 included) + wifi enabled according to one of WRTnode from http://openrouter.info/forum/viewtopic.php?p=36058 http://openrouter.info/forum/viewtopic.php?p=36058 and WRTnode is about 20g in weight.
- samcrawford 12y agoGreat effort, lovely little device. Building your own hardware is not easy to do cost effectively! But a few niggles: - Quoting RAM and flash in Mbits? Whilst that may be the norm for buying components, I'd argue most people familiar with OpenWrt and the Raspberry-Pi generation are going to miss this detail and think "Oh wow, 512MB RAM and 128MB flash!", when in fact it's 1/8th of that. - There's some mention of a standard shield, but no information on what it includes or when it will be available. - Like others have said, that scrolling on the website is extremely annoying. Regardless, I will definitely be buying one anyway.
- billpg 12y agoI once saw an SD card sold as "8gb" and thought it terribly expensive for that much capacity.
- chrisBob 12y agoAt least it wasn't "mb". I am not even sure how that would work.
- noonespecial 12y agoThe Mbit thing is quite common in the embedded world. When I saw this my first thought was "oh wow, twice the specs of my current favorite OpenWRT hack platform (the TL-703N) at about the same price and with gpio exposed. Awesome.)"
- samcrawford 12y agoHmmm I'd agree it's common when you're talking about components with hardware developers, but when you're pitching it to software developers/users then RAM/flash is almost uniformly referenced in megabytes. Take for example: - OpenWrt's table of hardware page: http://wiki.openwrt.org/toh/start http://wiki.openwrt.org/toh/start - Raspberry Pi specs: http://www.raspberrypi.org/product/model-b/ http://www.raspberrypi.org/product/model-b/ - Minnowboard Max specs: http://www.minnowboard.org/meet-minnowboard-max/ http://www.minnowboard.org/meet-minnowboard-max/ - Beaglebone Black specs: http://beagleboard.org/black http://beagleboard.org/black Oh and I love the reference to TL-WR703N, that little thing was pretty special! I was always disappointed by the MR3020, which is basically identical but a lot larger for no obvious reason.
- codehero 12y agoCan anyone comment on the read/write performance of SPI flash? Seems like it would be similar in performance to SD card, but without the wear leveling?
- bradfa 12y agoSPI flash is usually NOR flash (not NAND like you'd find in an SD card or SSD). NOR flash is usually SLC and will take 100k writes/erases and is quite simple to access (as compared to MLC NAND which only usually takes 3k erases and is a pain to access comparatively due to things like ECC requirement). SPI flash generally will do on the order of 0.5 MB/s erases, slightly faster writes, and somewhere in the realm of 4 to 12 MB/s reads, give or take. It's not high performance but it's simple, cheap, and low pin-count. The host controller is responsible for wear leveling, erasing each needed sector/block, and all writes, as SPI flash is unmanaged (compared to SD cards which are managed memory).
- listic 12y agoAFAIK, SD cards do not have wear leveling, SSD drives do.
- bradfa 12y agoMany SD cards have wear leveling built in, but most of the algorithms and CPUs used for the controllers are quite crap at wear leveling. If you start looking at more industrial targeted SD cards you'll find quite decent wear leveling.
- mmagin 12y agoMost of them do some kind of wear leveling, but they usually use cheaper flash and less capable controllers and the controller algorithms are mostly oriented around making them usable for sequential writes as you see with a digital camera, not for making a good drop-in replacement for rotating disks.
- coin 12y agoWebsite is totally obnoxious on a mobile device - no pinch zoom, no scrolling, must press little dots to "scroll".
- Apofis 12y agoWow, thanks, I didn't even realize there was more than one page because there was no scroll bar.
- dangerlibrary 12y agoIt's just as obnoxious to try scroll through on desktop.
- kazinator 12y agoAny electronics-related web page that uses "shield" other than as meaning "RF emission/reception blocking element" is automatically obnoxious, mobile or not.
- patja 12y agoit 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
- ErikRogneby 12y agoAn excellent price point with wifi included.
- noonespecial 12y agoIt feels like theres like a Lagrangian point out there in device space that these devices are converging on. It doesn't quite exist yet, but we are getting tantalizingly close. It networks like a Cisco, runs linux like a server, has GPIO like an Arduino, and costs as much as a Latte. Once it exists, its almost like computorium, becoming the center of nearly every maker project and then staying there because its so cheap you don't have to choose which projects get your precious dev boards. This is a fantastic step towards that goal.
- diminish 12y agoand it's sold in packs of 6 or 12 at your local discount store or walmart, right next to the pens.
- grizzles 12y agoSerious makers want this price point with an atheros chipset. In lieu of that, the open-mesh.com routers are a good choice if you are trying to do low level wireless innovation.

- api 12y agoThis 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.

- makomk 12y agoThere's several similar boards; off-hand I can think of the VoCore, the AsiaRF AWM002, and a couple of unbranded Chinese ones.
