It looks like a new Raspberry Pi 2+ is coming soon; maybe for industrial uses and supply chain reasons.
Then it will probably be not that cheap. I was trying to use RPi as kiosk inside of a warehouse. Even good filtered power supply was not preventing resets. So you cannot drive big electric motor close to RPi.
Is it normal in industrial contexts to run the controlling computers off the same power rail/ring/circuit/whatever as the machines themselves?
Absolutely not.
Try shielding it, put it in a small metal enclosure. Might not be noise on the power supply - just strong EMI so close to it will cause problems.
There is also cable from supply to Pi itself also network cable attached to it. So still current will induce in those. There was no other way for connection only to have those cables run vertically.
Have you put an RF chokes on the cables? Give that a try to add some inductance so you don't have to worry about the noise from the motors.
Also alfoil will go a long way for shielding.
How big of an electric motor is it?
Oh I have seen EMI shielding tape on some cables but I did not know what it is until I have googled for it after your comment.
Seems like something to try out.
Motor is 20kw driving less than 1 meter from installation. It is not standing there but it is mounted on machine, which comes at the spot from time to time, and while passing by it causes resets.
I hope so. I've been waiting for a replacement for the Compute Module for a long time. A drop-in CM2 would make my week!
A version with SATA or USB3 would be nice. That would extend potential use cases a lot since we could use faster storage.
SATA won't happen (unless they use USB-SATA bridge, like in Orange Pi - but then it will be all but fast) As far as I know, there are no modern low-cost ARM SoCs that have an integrated SATA peripheral. AllWinner was the only vendor that shipped one and they gave up on it after A20.
Built in Ethernet would be an improvement.
I'm guessing/hoping it's going to be very similar to https://getchip.com/pages/chip in both connectivity (WiFi/BT) and built-in storage... and hopefully price.
well I would hope there would be a new Pi coming out... eventually.
