ESP32

I want to use ESP8255, I think it has enough pins for what I want to do, but I'm waiting for delivery from China.
In mean time, I have a few ESP-WROOM-32 modules. Got 2 off Banggood for £3.42 each.
This is really too new, not fully supported by Arduino, but it is a very nice chip and a very nice module and I have some spare time.

Created a simple PCB to create a bread board friendly module.

Created minimum circuit, serial on TXD0/RXD0 to PC via FDTI, used FTDI 3v3 for power, reset momentary and flash/program slide switch.

Got the "Hello World" example up and running.

It's a good start point. Plus, I now have a new toy :-)
