You can well see it is an engineering sample, because I’m squeezing the wrong size packages into locations (quarter Watt resistors where eighth Watt components should be, etc) and using a mishmash of different component types, but you’ll forgive me, I’m sure.
The new design presents the Expressif ESP8266 device on an Arduino-sized board, supported by a full USB programming interface and power supply.
I should be careful to explain – this is not a “shield”. It does not sit on top of an Arduino. It REPLACES the Arduino. It IS the processor – and a whole bunch more…

It looks cool, of course. But I have to say I’m getting plenty of positive results using the microcontroller in the ESP-8266 v12. But I would still say this is something I would enjoy having this on my bench for some tinkering.
Looks like the open source hardware ESPduino UNO by Elecrow.
