This incredibly useful RS232 to TTL level converter uses the industry standard MAX3232 chip, providing a total of 4 channels, 2 in each direction. Simply connect to ground, apply power and connect your serial data inputs and outputs. No other components are required. The required capacitors are on-board. It is even small enough to fit inside a standard DB9 connector shell.

Can be used for two 3-wire serial ports with TxD/RxD/GND, or a single 5-wire port with TxD/RxD/GND and RTS/CTS handshaking lines.
