Since the CP2102 was updated, there has been a reversal of the labelling of TX and RX as Baite switched their convention for the UART, following... http://www.hardwarebook.info/DTE_DCE and probably to converge to the more famous FTDI module pinout.
Diagrams shipped with kits containing newer modules have already been switched but at some point the website diagrams need to be updated to match also, and some kind of indication given so that people can see there are two conventions, as it's feasible that people are using full-screen view of the online kit graphics when building, instead of the printed diagrams dispatched.
