Onion Omega2 IoT Computer

Nowhere near ready for prime time. Consider this as a BETA product as the interface is unstable, the apps don't always (or at all) work. What started out in KickStarter as the answer for a $5.00 computing chip has certainly ballooned in price. I have no doubt that Onion will work out the kinks eventually but they should have been worked out for the most part before going to market.

I own 3 of these things - bought directly from Onion - so here's my advice: Stay away.The problems with this product are numerous and make it an absolute nightmare to work with. First, the pins are 2mm pitch instead of the standard 2.54mm. You can't put this thing on a breadboard or even use that bag of jump wires you have sitting around with it. you either have solder your connections to it or buy one of their overpriced docks (seriously, the cheapest dock is $15 for a board with $5 worth of components).You also need a LD33 voltage regulator if you're going to run it without one of their overpriced docks. And yes, you NEED either a dock or a voltage regulator to get this thing going reliably because it's danged picky about its input current. Just using a 3.3v power supply isn't going to cut it.If you turn off the AP mode in the wifi module - a glaring security hole if you're planning to use it in an IoT device - the entire wifi goes away, leaving you with no way to access the board except though the serial interface. Which, since very few computers have serial ports these days, means you need one of their docks with the USB-Serial interface. To be perfectly fair the fault for this lies with MediaTek rather than Onion. They have the AP mode hardcoded into the driver for the wifi chip. There's an OSS driver you can get to work around this problem, but it has severe performance issues.Unlike every other SBC I've worked with, the Omega2 does not have built in pullup/pulldown resistors, which means you have to add a resistor to use a button on its GPIO. This is only a minor nuisance, but it is a nuisance none the less.All in all, my three have turned out to be completely useless for the project I wanted to use them in even after spending extra money on voltage regulators and quite a lot more time than I would have spent with a Pi or ESP8266 trying to make them work.It does have a couple of uses. It makes a decent wifi range extender or router. But as an IoT device? Save yourself some headache and get a Pi Zero W instead. It's about the same price by the time you factor in shipping and add a SD card and a whole lot easier to work with.

It not breadboard ready or any standard socket ready it is not a usable item for any DIY or IOT project and add $15 to $25 to the price to use it.

The Omega2 is a great little machine especially when used with its docks and capes. It can be fiddly to get going. It boots as a wifi hub and provides and provides a web page interface. You need to follow the instructions to connect the Omega to your own wifi hub and therefore the internet. Please note that it seems to hang at this point but leave it five minutes then reconnect your computers wifi to it and everything should be fine. If you have issues try refreshing your browser and / or reconnecting to the wifi.Don't perform a full factory reset unless you really have to as it boots as as ssh only and the web console has to loaded. If you do have to perform a factory reset you need to perform a manual install - follow the instructions on the onion manaul which follow the console based instructions. This is the best solution , I do not advise using the advice on the forums regarding installing the console.

Cumbersome to setup, but interesting to use. You really need a dock or baseboard to fit it on. I used the arduino dock. I can run a webserver with PHP7 which I found useful.It really requires a flash card to add space for your own projects.
