mbed&GPS em-406 position fix issue?
hello, I would like to use the EM-406 GPS with an mbed. According to the GPS data sheet (http://www.sparkfun.com/datasheets/GPS/EM-406A_User_Manual.PDF), the power input ranges from 4.5V to 6.5V DC. When I power the GPS with a battery (whitout the RX/TX lines connected), the position fix indicator is set after few seconds (in outdoor). However when I try to power the GPS from the mbed's 5V output I systematically loose the position fix. Any suggestion?
Thanks in advance!

I have not use this EM-406 GPS , and I dont know if this will help you. But check current consumption for your module. Sometimes you cannot just power external device from mbed board. Stable voltage is very important to get fix for most GPS modules on a market. I know that some modules in a moment that try to get fix drain a lot of current in a pike. So this can produce voltage drops.
