MAX3232 - RS232 to TTL module / converter AVR PIC ARM

Description:
 
This RS232 module is designed with 6-PIN header, it can be plugged into a breadboard directly.
It provides RX/TX, and DSR/DTR or CTS/RTS handshaking signals in TTL level.
It can be configured as a null modem without handshaking, or with DSR/DTR or with CTS/RTS handshaking.
It has standard DB9 female connector, and can be connected to PC with a straight 9-PIN serial cable.
It is build with MAX3232, it supports 3.3V operation in high speed.
It supports Microchip PICs, Basic Stamps, ATMEL MCUs and ARMs.
Header Pinout: VCC , GND , TX , RX , CTS/DSR , DTS/DTR。
