This seems like a version of the Tessel[0] that isn't as overpriced[1].

Why, it doesn't have a js interpreter or seem to use the same chips?

Anyway, this looks like a nice middle ground between the cheap chinese 5$ ESPs that are kind of a pain in the arse to work with and the rather expensive Ardu-whatever.

I'd love me some details though, couldn't find essentials like:

* how much power does it use

* expected throughput

You can program Spark using JavaScript too: https://github.com/spark/sparkjs

Those two don't seem to be the same thing. Tessel runs javascript on the micro so you can write your programs in js instead of C and compile it.

What you've linked to is a js library for connecting to Spark cloud.

Overall I think the Spark is much better bang for your buck.

You're right, although you can write your sketches using just JS: http://blog.spark.io/2014/09/29/blink-an-led-with-javascript...
