NimbleSig III RS232C  to 3.3V UART Data Converter PC Boards

    This tested and confirmed OK PC board design provides a mounting base for the NimbleSig III RS232C to 3.3V data converter. This converter can derive its power from either or both the CTS and DTR RS232C handshake signals which are usually present. There are however some poorly designed USB/RS232C adapters which do not provide either CTS or DTR signals. If neither of these signals is available as a power source then external power can be injected from an external 5-9 Volt DC power supply. An internal regulator is provided to supply a steady 3.3V power source for the level conversion.
