RS232 Module, DIL (RS232/TTL Level Converter)
Description
The RS232 module can be used to interface a microntroller to a PC via a RS232 connection (serial port).
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.
The module can be assembled with any MAX232 compatible RS-232 Transmitter/Receiver chip.
