We need the Rx/Tx of the ESP8266 for flashing, so the code in ``emsuart.cpp`` switches the UART pins to use RX1 and TX1 (GPIO13/D7 and GPIO15/D8 respectively). This also prevents any bogus stack data being sent to EMS bus when the ESP8266 decides to crash like after a Watch Dog Reset.
The breadboard layout was done using [DIY Layout Creator](https://github.com/bancika/diy-layout-creator) and sources files are included in the repo.

Below is an early messy prototype circuit using a NodeMcu2 with the additional LEDs and 5v buck converter. The inputs from the EMS are not shown but there are at J60 and J58 at the top left. If you don't want to build the circuit [bbqkees](http://www.domoticz.com/forum/memberlist.php?mode=viewprofile&u=1736) can sell you one which looks like the photo below running on a Wemos D1 Mini:
And here's an early prototype circuit using a NodeMcu2 with the additional LEDs added and 5v buck converter to power the ESP8266 also from the EMS line.
