There's a few things i would like to ask about this two components.
1. Power supply for GPS evaluation board.
I understand that the power supply for the evaluation board can only be tranmitted from USB and the barrel Jack. However, if im using the Rs232 interface instead of USB to integrate with my microcontroller, how much voltage should i provide to the barrel jack?
2. Switch on the GPS evaluation board.
There are two switches, one is the RS232/USB switch which i know. But what does INT/EXT precisely do?
3. Software Mini GPS
The mini GPS has no readings when i use the USB. and i didnt get to try in RS232 as the power supply has not been made for the board. Is there a driver to be installed? where can i get the driver to install on to my PC to check if its working?
