There have been complaints that ESPboy1 is hard to build for beginners and of course that's my fault, I got carried away with compactness and SMD.

But now I decided to go back to the source and finished a simplified circuit on large and cheap through-holes components.
Now you can buy all a few parts for less than $10 and even a kid can solder them. 
It's very hard to go wrong.

The compatibility to ESPboy1/ESPboy2 is 99.9% and an extension slot is provided.

So even on this simple device is available ESPboy AppStore, WebAppStore and in general all software and extension modules of the standard ESPboy.

Thanks to @MLXXXp for helping me design and the whole community for their support and inspiration :)

DIY you first own ESPboy!

Have fun :)
