The $5 Onion Omega2 Gives Raspberry Pi a Run For Its Money (dailydot.com)
An anonymous reader writes from a report via The Daily Dot: Onion's Omega2 computer may give the Raspberry Pi a run for its money if the success of the Kickstarter campaign is any indication. The Daily Dot reports: "With an initial goal of just $15,000, over 11,560 backers have pledged the company $446,792 in hopes of getting their hands on this little wonder board. So why are thousands of people losing their minds? Simple; the Omega2 packs a ton of power into a $5 package. Billed as the world's smallest Linux server, complete with built-in Wi-Fi, the Omega2 is perfect for building simple computers or the web connected project of your dreams. The tiny machine is roughly the size of a cherry, before expansions, and runs a full Linux operating system. For $5 you get a 580MHz CPU, 64MB memory, 16MB storage, built-in Wi-Fi and a USB 2.0 port. A $9 model is also available with 128MB of memory, 32MB of storage, and a MircoSD slot. The similarly priced Raspberry Pi Zero comes with a 1GHz Arm processor, 512MB of memory, a MicroSD slot, no onboard storage, and no built-in Wi-Fi. Omega2 supports the Ruby, C++, Python, PHP, Perl, JavaScript (Node.js), and Bash programming languages, so no matter your background in coding you should be able to figure something out." You can also add Bluetooth, GPS, and 2G/3G support via add-ons or expansions. It looks promising, though it is a Kickstarter campaign and the product may not come into fruition.
The Rpi isn't the cheapest board out there. There are many cheaper ones, many offering faster processors, more cores, built-in WiFi, etc.
Bang per buck, you can do better than Rpi. Even the Zero.
But what the Rpi does have over everyone else? Community and long-term support. The other cheaper boards often only release an ancient kernel and that's it - nothing more. Yes they can run Android, but the only one they release code for is Android 4. And if the driver is buggy, you're SOL - no one's fixing it.
But the Rpi community is what makes the Rpi the better board - there's lot of support, lots of people are keeping a maintained kernel for it, and drivers are actively being developed and debugged.
How's this board compare? What are they doing to ensure long-term viability of their hardware? Or are they going to build them all, then go onto the next generation, forgetting about what's out there already?
PoE for a tiny device like this, with built-in wireless, doesn't really make any sense. What makes sense is to stop trying to cram Linux into these things, and design them for low-power usage from the ground up. These are so-called "Internet of Things" devices, and will be single-purpose embedded systems. You do not need Linux to do that, it just gets in the way. I wonder how much current it needs to run, and how long it'll last on batteries, and whether or not it has any low power modes.
