Testers needed

[jvitkauskas]

Baseboard v2.2 has not been tested in real life yet. In case somebody has tested it and it works, I would be interested to know if it works.

It does not work! ))
I've ordered a board with fabrication files from repo...
In short, last two days I've soldered and tested two boards (the first one I had soldered have not worked, so, I've made an another attempt with a previous v2.0 circuit diagram (I've removed DC-DC convertor and put a 1N4007 diode on SJ1). And it have not worked, too. So, I've investigated the reasons and have found the error:
IC1 TCL393P is not powered: pins 4 and 8 are not connected to the GND and +5V, accordingly. So, measurements (according to the measurement plan were incorrect.
After powering TLC393P all measurement values have come to appropriate values (for v2.0 board)!
So, I've used ebusd (+ CP2102 UART+USB adapter) to connect to my Vaillant boiler and Calormatic 470 controller.

Later I've try to "power up" the first board (v2.2) and I'll report results.

Anyway, thank you for this repo! )) It helped me a lot in my way of home automation!

P.S. I'm not Eagle user, so I cannot propose a fix, so, it's up to you, I hope! ))

I've also found the error with the "external power" option )) It has the common ground with the ebus-line but the description says "galvanically isolated"
So, I've fixed the error by cutting two routes and making two additional "jumpers" )
So, the board works with my fixes ))

Also, I'd propose to change a form-factor of a board to be able to insert it into a DIN-rail box, for example
