Anyone who is looking for a serial cable solution for their Android smart phone or tablet will be wondering about the different options on the market. You may have even found a model, heavily advertised by the mainstream retail outlets, which is marketed as a micro USB to RS232 serial adapter cable for Android. However, it won't be until your money is spent and it turns up on your premises that you realize the problems. This heavily promoted cable does not have a power source and actually depends on the availability of an AC adapter! This requires a second wire to be added, and you end up carrying six feet of wire in your pocket. This is not a very mobile solution.

On the other hand, the Android RS232 serial cable PDCA-M9-6 from pcables.com long ago overcame all of these problems. What you will get when you order from pcables.com is exactly what you wanted, and nothing extraneous. Instead of six feet of wire, what you get is six inches - perfect if you need to carry it around. And now for the most ingenious part. The PDCA-M9-6 is powered directly from the Android! When you plug the cable in, the Android is smart enough to power the cable through the micro USB adapter.

The PDCA-M9-6 works with Google Nexus 7, Samsung Galaxy Note 3, and in fact any Android which supports OTG host.
