@Douglas-Kryder WOW! Great suggestion! Thank you!

Greetings,

As a kick starter contributor, I've been intrigued by the Onion since its beginnings, now that i finally have one in my hands, I've officially fallen in love... To the point where my first project is an industrial automation control and monitoring device for a mission critical application at work...

However, I've ran into a head scratcher, and its purely a hardware issue. The OnionOmega2 is an AMAZINGLY powerful and small platform but if i want to use any of the Expansions, i have to use a dock, and all of the docks that support the "expansion connector" DOUBLE the footprint of the onion.... Which to be blunt, in my opinion, is dumb... Additionally the use of a "non-standard" pin-spacing on the onion itself while justifiable to maintain its small form-factor. goes to even further complicate its integration...

Personally I'd love to see something like the Proto Expansion released, with the "Onion Jacks" on it.. Leaving the pins Via's available for prototyping, But also have possibly either solder-bridgeable or cuttable traces that plumb the Onion pins over to the standard Dock-Expansion connector. So someone could use the same plug on modules available

Fantastic product Dev-Team! i love this thing and i cant wait to make it do amazing things. BRAVO!

Thanks for your time.

Omega Stuff for Sale

Jed Wood — Mon, 25 Dec 2017 22:58:44 GMT

@György-Farkas I’ve never shipped anything to Hungary, but this would be a small and light package. Seems like it shouldn’t cost too much to ship(?) I’ll send you a DM. EDIT: Does this forum even have DMs? Please drop me an email to my first name at LimeChile.com

Will any dock ever be back in stock?

You can order via the indiegogo campaign. it is dog slow, but works.

Power Dock vs Expansion Dock

Manuel Godinez — Fri, 20 Jan 2017 15:10:52 GMT

Wouldn't be better to just add to the Expansion dock the charging/battery capabilities? There is a lot of room for that in the PCB.

Omega 2/2+ Without Any Dock

Vijayenthiran Subramaniam — Fri, 03 Feb 2017 14:21:46 GMT

I am planning to create my own custom dock. Instead of CP2102 USB to serial converter, I am planning to user CH340G which is easy to solder. For power supply, I am planning to user AMS1117 since I assume that Omega2 does not require more than 300mA. I notice that in the schematic, the voltage divider is used between PC_TXD and RXD. Is it to reduce the 5V to 3.3V? I am planning to use CH340G with 3.3V power supply. Something like this. If do so, should I use the voltage divider network? I assume that I don't have to use. Will post the schematic for the review once I complete.

Dock Options

@Scott-W-Wood I can only reply in connection with the original Omega and original Arduino Dock - I have not yet received my Omega2 and new Arduino Dock R2 - there is no documentation I can find on the latest versions that would allow me to respond definitively on them, though the photos shown on https://www.indiegogo.com/projects/omega2-5-linux-computer-with-wi-fi-made-for-iot#/ for the Arduino Dock R2 show that there are some differences and I don't know how significant these differences are. However, from my experience with the original Omega and original Arduino Dock I can say that the USB connectivity is to the Omega in the same way as it is for the Expansion Dock and Mini Dock - see the schematics for the Arduino Dock (https://github.com/OnionIoT/Onion-Hardware/blob/master/Schematics/Omega-Arduino-Dock.pdf), Expansion Dock (https://github.com/OnionIoT/Onion-Hardware/blob/master/Schematics/Omega-Expansion-Dock.pdf) and Mini Dock (https://github.com/OnionIoT/Onion-Hardware/blob/master/Schematics/Omega-Mini-Dock.pdf)

omega 2 docks

chr314 — Thu, 29 Sep 2016 14:38:51 GMT

@Matthias-Nowak thanks i want to connect 2-3 motors (with driver module i guess) and few sensors, omega2 + expansion dock can handle this?

Physical dimension of dock /expansions

Boken Lin — Mon, 08 Feb 2016 06:30:13 GMT

Hi @Johan-Simons , sorry about the late response. We have done some technical drawing for some of the PCB's we have, and you can download them here: https://wiki.onion.io/Technical-Drawings/Omega-and-Expansions-Technical. We will be adding more to this page every week. Cheers!

Pinouts for Omega, docks, and expansions

Kit Bishop — Mon, 21 Mar 2016 21:45:28 GMT

@Benjamin-Rau I have just had a play with my Omega and pins 13 and 14 when set as input both operate equally and as expected. Unless there is a problem with my Omega, there are a few things you could check (forgive me if these are obvious to you or you have already done them :-)): Are you sure that the circuitry is the same for 13 and 14? Is the code used to access each of 13 and 14 the same? Is there anything else that is using one pin but not the other? If you are using mechanical switches to control the pins, do you have a suitable pull-up/pull-down resistor to pull the pins to the appropriate state when the switch is open? If you are using mechanical switches, do you have suitable de-bounce circuitry to account for noise? A capacitor in parallel with the switch (along with the use of pull-up/pull-down resistors) should handle this

Power switch flew off.

Hi @Brett-Shipes, I'm very sorry about wasting your time. It is our fault for failing to ensure a quality in our manufacturing process. Would you please just try turning the switch with a pin one more time as shown below. If that does not work we will give you a full refund. The red arrow points to the location where the switch has broken off. What you should try to do is to use the tip of the needle to push it to the right to the ON position. Another thing that I have noticed is that your Omega isn't fully plugged into the dock. So it could be that you have already turned the switch to the ON position, but as a result of the improper connection between the Omega and the Dock, it wasn't able to turn on. So please push the Omega all the way into the Dock before trying to turn the switch with a pin. Thank you for your patience in dealing with us, and I apologize again for wasting your time.

Suggestion: Announcement, Categories & Roadmap.

@Boken-Lin said: @T-NT Isn't monday the 30th of November? Opps. yeah.. getting ahead of myself. Keep thinking it is December already. Too cold and windy here that's why And RSS is a great idea! I will make sure I add that to our to -do list Cool.. I appreciate if I can keep up to date with changes and new products.

Need info on how to plug omega into either dock

Anco van der Kolk — Sat, 14 Nov 2015 21:24:42 GMT

there is also a picture with the Omega and antenna mark (but indeed not so clearly)
