Mini RS232 to TTL Converter MAX3232 CSE Board

This is a very small handy mini module for prototyping projects requiring RS232/PC interface to robotics
and microcontroller based projects using 3.3V to 5V TTL logic.

This module converts signals between RS232 voltage levels and TTL voltage levels.
It is bi-directional, where TTL signals are converted to RS232 levels and RS232 levels are
converted to TTL levels.


+3.3V or +5V signals levels at the TTL level.

Up to a maximum of 120Kbps Data Rate

Suitable for interface to Microchip PIC, Atmel AVR and other such micros.
