AR9100 : 3 questions
1) The documentation says minimum voltage of 6V. Is the following an acceptable solution : 2 Lipos with a good quality regulator (Emcotec, Fromeco) at 5.5V. This would still maintain a margin to the minimum 3.5V
2) Battery management. If you use 2 batteries, are these used at the same time or is there a switching from one to the other according to voltage drop.
3) Can you use the AR9100 without the switch. This is in the case where the regulator already has an electronic (fail-on) switch.
Thank you
