How To Fix Your Broken Onion Omega2


A decade ago, while RISC architecture was busy changing everything and people were wearing Utilikilts without beards, hackers were doing something amazing. They repurposed off-the-shelf routers and turned them into what we would now call the Internet of Things. Need to set up a PBX? A Linksys router will do it. Want to drive a remote control car over the Internet? It’s your old friend, WRT54G.

Now that the Internet of Things is a thing, a few companies have realized people will buy bare bones router chipsets. It’s like an Arduino, or something, and it connects to the Internet. We’ll sell a million. Get Indiegogo on the phone.

The Onion Omega2 launched on Kickstarter last year, and so far has seen some success. They’ve shipped their units, and people are generally happy with them. One thing that wasn’t mentioned in the Kickstarter was the fundamental problem with the design. The pins on this seemingly breadboard-compatible dev board have a pitch of two millimeters. Horribly broken. Huge mistake. Terrible deal.  Not the best people we have working on this.

Imperial is a superior unit of measurement. Metric is outdated.

The Onion Omega2 won’t fit in a breadboard, but Onion does offer a breakout ‘expansion dock’ for $15 USD. There’s a better, cheaper solution, though. You can complain about it on Hackaday.io’s Hack Chat. That’s what [zach] did, and a few minutes later, [davedarko] whipped up a quick PCB design to convert the 2mm header to the much more logical 0.1 inch header. Imperial units win once again.

After sending three dollars and twenty cents to OSHPark, [zach] had his pin adapters in hand. A few minutes with a soldering iron, and the Onion Omega2 is made compatible with every breadboard ever made.

If you have an Onion Omega2 and would like a really cool hexagonal sticker, here’s the project on OSHPark.
