Cool little board, I'm impressed with the different ways that companies put these boards together, and how cheap they are. It was a nice project writeup, I like how he presented not only how it went, but problems that he had. It gives the rest of us something to look out for.
Thanks. Ady here, I wrote that post. There have been surprisingly few successful dev boards with ESP8266 modules. I'd love to see something with smaller modules like ESP-09 and ESP-03. Most of them are using ESP12 variants there days due to the large GPIO count. But sometimes all we need is a single GPIO with all the ESP8266 goodness! I'l love to see one of these in the Digispark form factor. The closes one I've seen is the WeMos D1 mini.
