Why a .RAR file? Anyway, you just do it like this page shows:

Your device address is 0x50 since A0, A1 and A2 are grounded according to the schematic you posted.

"WinRAR does seem to live up to its claim to be the fastest compression software. In the "Default" section WinZip takes less time, but it does so by giving slightly worse compression. (All compression numbers here are low because I was working with music and image files, which do not compress very much. Documents may compress by as much as 75%.) I didn't do formal tests, but uncompression of RAR files also appears to be slightly faster than Zip."
I have those modules on hand, but never have chance/time to use them, sit in garbage bag I bought back from Shenzhen for my son. I did not have document either since the store owner who sold them to me is purely box mover. He have no clue what he sell but in price and out price. He told me he never attend school after 5th grade. I asked my co-worker call the OEM to obtain document. I did a little clean up by replace Chinese file name to English one and upload here.
btw The store owner manage sell his staff via ebay by hiring new graduated English major students (girls) who know nothing or care nothing about electronics, and he is so proud to tell me the ebay's sell is up.
