This is a simple board that no one really needs but it sure comes in handy. If you've ever tried to hook up an FTDI to something only to realize you need to swap the TX and RX, maybe you could use this board. Sure, you can grab some jumper wires and make your own, but this little crossover board makes it much easier.
The board has a set of headers going in and a set going out. The TX and RX lines are swapped so you can connect it to a Bluetooth Mate and configure it without having to swap the pins coming from your FTDI.

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.
