Lots of packages were swapped. Connectors rotated, moved, rotated, then put back.
Fun stuff, for now.


Seen on the right lies the almost finished mains management, as indicated by the milling for bumping up the creepage distance.
This area consists of two triac-based AC switching units, tested to switch up to 800W at 230VAC combined with MOC3031S optocouples to drive those.
In the bottom left corner the input protection circuitry for the switch-mode converter can be found. In theory this should protect against all kinds of troubles later, given I implemented the application note correctly.

The secondary side consists of an ARM Cortex M0, various interfaces and of course the famous ESP8266.

Of course there are still serious issues with the current layout like general part clearances and trace widths on the primary sides, but I am positive those will be gone soon.
