Hi all. I am just putting the finishing touchs to a project hat uses a GPS. One ofthe things that is a but annoying is the wait for the GPS to kick in. I hve seen some kits where he GPS has a battery (a watch type battery) which I can only assume is to keep the GPS alive so to speak so that when a project used it, it doesnt need to warm up (if thats the phrase to use). So taking it that this IS the case and I want to add a battery to my GPS, what sort of things would I need to consider?
2 things come to mind. 1. It can prob run off the small battery ok, but do I need to handle the fact that it now has 5v coming to it, and switch of the battery circuit?
- what about recharging? I am not sure that the other circuit I have seen had a charger built is,so maybe the GPS draws a small about of current when th small battery is in use.
I am not 100% sure of the above as you can tell, and would welcome any suggestions etc.
