[RC232] “i have some questions for RC1701HP-RC232. Need the “tx” pin a levelshifter or driver-ic (our previous experience with RC1280 was a f—ing 100KR impedance!!!) ? Are on the “tx”, “rx” and “cts” pins resistors in series? Can I connect “tx”,”rx” and “cts” directly to a MCU (XMEGA @ 3,3V)? “

RC1701HP is supporting 3.3V I/0 directly to/from 3.3V MCU and no additional driver is needed. For MCU consideration please see data sheet page 8 for details.
