This is something similar that's about to get released and way faster: https://neutis.io/

The Neutis is $49, the VoCore2 is $18. They seem to have different power consumption as well. While it might be similar in size, the cost difference is substantial. The best choice as usual depends on the project.

Similar to the Omega2+: https://docs.onion.io/omega2-docs/omega2p.html ... except Vocore2 is slightly smaller and the Omega2 is ~30% cheaper and has an SD card slot.

Vocore2: MT7628AN 580 MHz MIPS with 128MB DDR2 and 16MB NOR: $18

Omega2+: MT7688 580 MHz MIPS with 128MB DDR2 and 32MB flash: $13

Both have b/g/n Wifi and are 10/100 ethernet ready. Omega2 software is based on LEDE.

Note that there is a SMT version SoM of the Omega2+, the Omega2S+ which is around $10 per unit when buying trays of 50.

I have one from the original crowdsourcing campaign, with an audio dock. Interference makes the sound quality is so bad it's unusable for any practical purposes. Support was useless. http://forum.vocore.io/viewtopic.php?f=16&t=3500&p=5185

HappyAlbatross is right: you definitely have a grounding problem, either due to missing proper ground or having a ground loop somewhere. Also if you're using a switching power supply and/or a class D amplifier (that is, a switching amplifier [1]), they can be real nightmares if not properly filtered, and cheaper ones almost never are. Grounding and ground loops, filtering and decoupling are complex issues which would…

Would you be able to test to see if your problem is power-filtering related by powering the board from a battery rather than from the wall?

My experience is that SD-cards don't last very long when used as the `/` directory.

Use a read only root fs and overlays in ram, this will keep your sdcard based Linux server running much longer, though it is a bit tedious to set up.

Interesting. How does this sort of set up handle updates?

You could ab update using dd to write to the other partition(s)

Oh dear - no HTTPS on that page. But, it does host a store section that lets you add stuff to your cart and then click a checkout button. That button takes you to PayPal (unless an attacker re-directed you elsewhere). Its not clear to me that there would be any real way to verify that what you are paying for the stuff from that website - it seems relatively straightforward for an attacker to modify the PayPal link to…

I e-mailed the support email about it. I got a response back - I think I convinced them to do it: "Thank you. You are correct, I will go to godaddy and get one :) it is fashion. Regards Chin"

Or he is telling me to get lost.

Ditto on the pin size. I wasn’t able to find utility out of it

You may find interesting the NanoPI Duo: https://www.friendlyarm.com/index.php?route=product/product&... Not in the same league (faster + more RAM but bigger + more power hungry), but the breadboard friendly form factor makes it very close to be the ideal minimal Linux module.

This thing is dense!

It seems a full day has passed since you've posted the message. I've just checked the store and it's still served through a plain old unsecure HTTP connection.

It seems you were told to get lost.
