I have received and built and tested a minDUINO v1.5 board. It operates as expected and the FTDI header now suits the FT232 module that I purchased on eBay. I also tried out a resonator instead of a crystal and that's all good too. I usually have my boards fabricated in Blue but I chose Red this time, just for something different.
Hopefully the v1.6 boards will arrive shortly and I can test those too.
