Ah yes, the big WeMos is also good, but the Uno form factor is just too monstrously large these days.

I also designed a tiny breakout board that's pretty much the size of the ESP8266 12E plus some pins (https://github.com/skorokithakis/tiny-ESP8266-breakout), but it's just that, a breakout. I definitely prefer the WeMos for most things, nowadays.
