Hi, Is it possible to get power of 5v from the 9 pins serial port? I would like to power my circuit which is max232 and RF Transceiver module. I'm planning to make them function without using any external power supply but just to use an excess pin from DB9 and get 5v from there. I'm already using RXD, TXD and GND pins of the 9pins serial port. Is there still available 5v pin generator? Thanks a lot.
