You have an Asus Eee PC and you don’t know how to connect it with GPS unit? Well, in this case, the RGM-3550LP GPS module might be the useful tool to help you overcome the problem!

The reason why you should use this RGM-3550LP GPS module, as it has an integrated antenna and is fully-powered by SiRF Star III technology. In this case, all you need to do is connecting the GPS module to the computer’s serial port by using a Max232.

If you’re using a notebook computer, then you should use a UART to USB bridge, since notebook don’t have a serial port! The FT232 is the most common used UART to USB Bridge, and it’s fairly cheap too, where it cost about $4! Don’t worry about it, as it’s very easy to use the chip and program some features saved in the internal EEPROM like the maximum bus power.

Although the FT232 has an internal regulator, where provides 3.3 V and 50 mA, but it’s better not to use it. As a result, you might need to use the TSP2148, where is a 3.3V LDO. The TPS2148 can handle all the current limitation without any further modification. [youritronics]
