Standard serial interfacing of microcontroller (TTL) with PC or any RS232C Standard device , requires TTL to RS232 Level converter . A MAX232 is used for this purpose. It provides 2-channel RS232C port and requires external 10uF capacitors.
The driver requires a single supply of +5V .
MAX-232 includes a Charge Pump, which generates +10V and -10V from a single 5v supply.
- MAX232 (+5V -> +-12V converter)
- Serial port male 9 pin connector (SER)
