RS-232 level converter

This is a basic RS-232 transmit/receive circuit that is necessary for PIC microcontrollers to communicate with a PC serial port. The PIC microcontroller operates at TTL levels (0-5 Volts). The MAX233 IC allows you to convert microcontroller voltages to RS-232 compatible levels with no required external components.


Components Required:
Max233 IC
DB-6 Female
1uF/25v Electrolyte Capacitor
20 pin IC Socket
JP1, 2 pin connector/jumper
