Finding an upgrade board for an Imp is getting pretty hard. So, I decided to test my tinkering skills and get one of these. Now, if you don't have a basic understanding of electronics, fabrication or soldering skills, do yourself a favor and get something else. Installing it wasn't hard, it just requires time and patience.
After getting everything installed, I have to say, I was impressed. Lots of modes, good eyes, and outstanding support from Scenario Dreams. It amazes me that a board the size of the top of a 9-volt can be packed with all the features above.
Programming can be complex until you get the hang of it, after that, easy!
I haven't had it long, but it is impressive so far. The only thing I wish was available for it is a computer interface and software to program it. Other than that, Great board!
