Operates at up to 128 kbits/s Low supply current: 8 mA Operates from a single 5V supply Inexpensive solution for adding RS232 connectivity to your device Connection pads compatible with all standard prototyping boards: 2.54mm (0.1") spacing
A standard RS232C serial interface on a PC uses voltage levels between -12V and +12V. In order to adjust this signal to voltage levels present on a microcontroller's TTL pins, and vice versa, it is necessary to use a voltage level converter such as the MAX232N Dual RS232 Driver/Receiver found on this board. This MAX232 Board has a female DB9 connector for RS232 devices (typically a PC), and a row of six pads to install an interface for connection to a microcontroller system's USART. Nothing is soldered into the pads, so you can add whatever kind of connector you need. A strip of male header pins is included.
Note: This board uses 5V power supply only. Be sure to use voltage translators on communication lines when connecting it to 3.3V systems.
