Look at Digistump Oak[0]. It's still in pre-order but the company has delivered many products at this point, and it's expected soon this year. [0] http://digistump.com/products/145

Yea, the Oak is probably the one that I'm the most excited about. I also backed one of Digistump's earlier kickstarters and was very pleased with both the hardware and the support.

I'm concerned about the TCP stacks on these boards. Near as I can tell, they're all built into the chips and no source code is available. Is my impression correct?

Yeah, they're pretty much black boxes. You are literally talking to them like you used to work with modems. "AT+" commands and all of that.

You can program the ESP8266 yourself. For its TCP stack it uses lwip which you can also compile yourself. The 802.11 stack is more of a black box though, but not necessarily the TCP stack.

i totally love the esp201. its very convenient to work with in eclipse/code blocks and can run C and C++. the documentation is a bit sparse though but thats mostly no problem as theres a great community behind it.

But the biggest point for me is the size + the price. Why would one use a Raspi or Arduino to read out some moisture-meter if it can be done with a 3 dollar hardware piece the size of a fingernail?

The article states that it lacks analog input, so that might be a good reason.

Nice. Is there data about expected throughout? I'm interested in audio streaming.

What are the power requirements of WiFi gadgets compared to other wireless tech? I was under the impression that WiFi wasn't a good choice for embedded because it's so power hungry that it can't be powered for extended time on batteries? There aren't many places where I want tiny wireless things where I also have access to AC power. That's basically limited to sockets/switches.
