Hi,
I'm new to this GPS thing..
anyway.. i have a few questions
1) I'm running a 5V micro contrller that can only hand 3V as minimum for logic high (I'm just gonna say 3.3V is the lowest)... the EM406 outputs 2.85 as logic high... what do you guys suggest I do in order to be able to shift voltages from 2.85V => 5V for reading the module and 5V=>2.85 for writting to it....
2)
The data sheets on the EM406 aren't very specific... WHen it starts up.. what do i do?? do i have to configure it.. do i have to send stuff to it?? what happens?
3)
How do you gyus normally power the unit? I have a 5V regulator, but the GPS unit has it's own regulator.. as far as i know.. it's bad to chanin regulators.. so what do you guys do?
