So, I have my batch of PCBs for rev 1.3 ordered and on the way. It will still take some time for them to arrive and for me to populate and test them, but just as a quick summary, here's what I am hoping to achieve with this revision:

Also, the software still needs a lot of work, so I would like to polish it a little bit more, add autoranging, make the software remember the range you last used in given mode and also implement proper UART/USB control (so it can be fully controlled from a PC using the isolated USB interface).
