I am checking out my new Bobuino2s. http://www.crossroadsfencing.com/BobuinoRev17/
No more memory or ram limitations.
Lots of I/O, a RTC, RS232, level shifting, bread board area, and comes with SD card stuff.
You got me on the Comm1 jumpers but it only took me 30 seconds to pull the shunts.
Even comes with a 5 minute air supply for underwater work
I was just kidding about the center LED being off shade
I highly recommend the Bobuino2 PCB to those of you who need a UNO comparable, all in one product with lots of memory.
P.S. We in Canada like 6-32 mounting holes for the stand-offs, but I did have some 4-40s so I guess it's OK.
