USB-TTL adapter module

Got a new USB-TTL adapter for generic use. Based on SiLabs CP2102 chip and the module is very cheap - $3.29 shipped from ebay. Supports 3.3V and 5V and comes with lead cables for connections. Tried for my Baofeng radio and works just fine.
Tried on Windows XP (drivers from Silabs) and Ubuntu (default drivers).
