@Alphalove
I highly recommend itead products, especially for those just getting into MySensors. They remove alot of the pitfalls that electronic noobs (such as myself) encounter when building their first sensor nodes. I used the RMini to build my first relay and it could not have been easier. Many of the troubleshooting problems posted on the forum have to do with setting up relays and these boards eliminate many of those issues.
I also recommend the nano shield from itead to any entry level electronics noobs for setting up early sensor nodes who are not ready for intricate soldering. It provides a nRf socket and a power jack and breaks out all of the nano pins with individual power and ground headers. Just plug in a nano and nRf and program from USB and power the entire setup through a single jack - perfect for beginners.
@fets So far, I have only built the 5x5 board (but the others should be schematically identical). The only issue I have found so far is that I cannot get the ISP port to work. But I have checked and I have an identical setup on the 1.0 board and that worked, so I suspect the programmer is too weak to drive the net on this one. So it is not a board-issue per se, and might only be an issue on the 5x5 board as routing is the most complex on that one due to the size.
