This RS232 to TTL Serial Interface Module is a board with the MAX3232 transceiver integrated circuit (IC). It facilitates serial communication between TTL and RS232 ports by providing the necessary electrical signal conversion. These boards usually have a DB9 connector soldered at one end, and four header pins with jumper cables at the other end. The jumper cables enable the user to connect the wires to a breadboard or a microcontroller project board, whilst the DB9 connects directly to a COM port of a computer.
The MAX3232CSE+ IC comes in a 16-pin narrow SO package. It requires between 3.0 V to 5.5 V to operate and has two receivers and two transmitters. It has a maximum guaranteed data rate of 120 kbps, and the circuitry requires four 0.1F charge-pump support capacitors. It is also compatible with the famous MAX3232 IC pins. These boards connect to systems with a UART; hence, they work with ATMEL and PIC microcontrollers.
This module can be used to the serial port of a microcontroller module to expand DVD, router, hard drive, and other equipment for an upgrade.
