RS232 TTL to USB

I’m often hacking around with some device that has RS232 but at TTL levels and I quickly want to connect it to a PC for some testing or set-up, but I came across these wonderful devices ready to go out the box :-

TTL RS232 to USB convertors

TTL RS232 to USB convertors

Available from RS Components http://uk.rs-online.com/web/p/interface-development-kits/6877770/ there are 5V and 3.3V TTL versions available. They are not the cheapest things in the world but they are ready to go directly into your TTL RS232 level device and come on a standard 0.1″ pitch connector that also provides +5V if needed.
