USB to serial adapter in DB9 footprint

There aren’t many simple ways to add a USB interface to a project using only through-hole parts. This USB-serial adapter from FTDI has the same shape and pinout as a through-hole serial connector.

It’s a little pricey (~$22), a USB->serial cable is usually cheaper, but it’s a nice option for a professional-looking USB device without surface mount parts or a USB firmware.

  1. Other than the cost thats a good idea, i’m forever losing cables, but I think at $22 a time I might start being more carefull :)
    For a finished project that needs to be used almost daily I would consider these.
