Well, phhhttt, you just found a problem in our SKU system. In our SKU system, this board is 0019-WEATHERPLUS-DSBT and the number is clearly 0011 on the board picture you sent and also on our all our stock.
I got the 'NOP' sketch "working" but while verifying that I could also re-build the latest SDL version (021) as a start, I ran into a couple of 'gotchas'
I am guessing that the SDL development team runs the Arduino IDE on a windows platform because I was 'bit' (only for a few minutes) by the filename uppercase/lowercase gremlin. I am using Linux to run the IDE :-)
