Arduino Pro

You program the board using one of the USB to Serial cables. In fact, the host connector is pinned out to match the FTDI TTL-232R-xV. There are 5V and 3.3V versions of the board.

There is a theme with the "Pro" series, which includes the Pro Mini and Pro Micro. That is one of simplicity. Nothing is included that is not universally functional. The USB converter was left off for practical reasons. It costs around $4.00 to put it on, and "Pro" users don't want to pay for the converter to load code, then give it away with the project. It is an idea that makes no sense at all, unless you are doing this more than once, and it pays for itself after about three boards. We keep several USB to Serial TTL cables hanging in the workshop, in 5V and 3.3V versions.
