FTDI USB to TTL Board Revision X5

See Board Revision X6 for fix to major board layout problem with this board.

The FTDI USB to TTL Board Revision X5 is a substantial departure from previous versions of the FTDI USB-to-TTL boards. Some of the differences include:

Different FTDI chip (FT230X instead of the FT232RL). The FT230X is less expensive than the FT232RL.
Smaller form factor. Still 1" wide but narrower.
Moved the connectors (USB and otherwise) to the back side of the board. So the back is like the front except that the chip is on the other side of the board from the connector.
Moved the USB connector closer to the edge of the card. This will help the connector stick through the side of the enclosure it is in more easily.
Set VCCIO to 3.3V so that the board can work with 3.3V or 5V interface cards.
3.3V/5V Header selects the voltage that will be provided from the FTDI USB to TTL Board. Note that the 3.3V has serious current limitations since the FT230X provides the voltage regulation. If the jumper is left off the header the board can provide its own power.
