RS232 adapter with an on-board regulator which can, if possible, use the DTE ‘s (such as a PC) RTS/DTR voltage to power the Max232 IC. The RTS/DTR lines are protected with fast switching diodes. An external power supply can be used if the DTE device cannot provide sufficient power on the RTS/DTR lines. Jumper selectable. Pinouts for CTS,RX,TX, GND , plus for an external supply, if required. Includes an LED to indicate power supply. The kit mainly consists of surface mount parts. Simple to use. Connect your projects’ TTL RX/Tx lines to the AD232SP and run a common ground wire between the two. When the DTE, (such as a computer with a serial port) opens a terminal application, the AD232SP will become active and the power LED will light up. Requires Assembly
