RS232 Level Converter

If one wants to connect PassMe serial interface to devices with RS232 voltage levels (such as a serial COM port of the computer), one has to use a level-converter. Here is a small level-converter I made using a MAX3221 chip. It plugs right into the serial interface connector.
