This is small supercomputer!
My first distribution (Slackware 2.0) was running on a P75 MHZ with 8 MB.

#12Related: The Octavo systems system-on-package: https://octavosystems.com/ It's a TI AMxx series linux computer in a package on package module like a raspberry PI is. It comes in two variants, a regular pitch BGA and an ultra wide BGA so that it is actually possible to hand solder it! (or with hot air or a toaster.) It is what is used on the Pocket Beagle. It saves you the need to to most high speed signals and really…
The thing just is that TI didn't exactly retain the people that know the internals of the OMAP series. If you hit any bugs you're on your own unfortunately. (Your milage with the existing documentation may vary also).

#14I could not make out from the documentation - are there are GPIO pins as on the Raspberry Pi?

Do you know the fischertechnik toy line? It's a little bit like Lego technic (fischertechnik fans will hate me for this comment because fischertechnik appeared in 1964, while the first Lego technic was introduced only in 1977).
They have a programmable controller for their robotics models: 600MHz ARM CPU and 256MB DDR3 RAM. We are talking about a toy line here :)

Click though to product page, full specs are listed: http://vocore.io/v2.html
“Around 40” GPIO pins

#17The problem with Linux in these applications is that it's not a realtime OS.

You don't actually need RTOSs for most practical applications. Even SpaceX used stock Linux.
That said, Linux can be built in a realtime mode.[1]

#19This project looks awesome. I can imagine it being used instead of the ESP8266 in many of my IoT projects. That would be a huge time saver. It will start to become competitive once it is actually cheaper than Raspberry Pi Zero. Especially as the Vocore2 is MIPS-based.
My main issue with using a full-blown linux device for IoT is that it's a full blown linux device. Not only is it harder to get up and running IMHO (vs just flashing your code to esp8266), you need to maintain a full OS which is a hassle security wise in the longer term. I get that there are some advantages, but overall I think IoT is better off as simple as possible.
Also, it's not possible to take the RPi zero seriously until they start shipping in any serious quantity - I don't like the play they've made by keeping it scarce.
