[OpenTRV-dev] Just got back from the London Arduino event...

[Damon Hart-Davis]

Spoke to Mr Margolis about getting the bootloader into blank ATmegas, running off 2xAA NiMH, etc.

Maybe using the ATmega as in the Leonardo is best, with the integrated USB (avoiding at least 2 external packages).  Also, a clip on device for the SMD part is available allowing another Arduino to force the bootloader into the blank ATmega in situ on the board, which thereafter allows the USB to be used for reprogramming or normal serial in the normal way.
