This is more of a note to self than anything else.
I inadvertently purchased some clone Arduino Mini Pros, insted of Minis, the difference being that that latter has a USB port onboard. Oh well, that meant securing an FTDI board or two, no problem there.
When they arrived, however, the pinouts on the FTDI boards were not labelled in a corresponding manner to the boards. Which wire went where? Who knows?
Some hunting later it ocurred to me that by simply plugging them both into a breadboard they would probably work just dandy. So, in went an arduino and an FTDI board head-to-head. Nada.
The magic happened once I downloaded a driver from here: from http://www.ftdichip.com/FTDrivers.htm and that’s all it took.
