[arm-allstar] Recommended Nano version --was: Why Arduino?

[David McGough]

Hi Guys,

The recommended Nano board is the 5V, 16MHz clone version, using the
ATmega328p and CH340g USB-UART. They're available from -hundreds- of
sources and are locally available everywhere I've checked. The Arduino is
OPEN SOURCE hardware/software, not proprietary. They'll be available in
some compatible format for a long, long time to come. See this link to
ebay as an example:

As has already been mentioned, see these links for interfacing examples. 
Note that this is still a project in development and the hardware methods 
are continuing to be refined.
