# Serial Pi Plus
|
||
|
|
|
||
|
|
The Serial Pi Plus is a UART to RS232 serial converter for the Raspberry Pi.
|
||
|
|
|
||
|
|
The RS232 port is connected to the UART port on the Raspberry Pi using a MAX3232 interface. The MAX3232 IC converts the 3.3V UART port to RS232 voltages allowing communication with RS232 compatible devices over a DB9 serial cable or with the use of a null-modem cable the board allows terminal access with linux on the Raspberry Pi using a terminal application. The RS232 port can be accessed through the DB9 port or the solder points on the PCB.
