never received the board
I hadn't received the board yet. I contacted the seller, unfortunately he said that the board can't be send because it is obsolete and not under production. I didn't receive a refund. Lost money.

Works perfectly
This is one of those things that I have built, but never really thought it was done right. Good soldering, well thought out. Fantastic support.
