Kevin Redon kevredon at mail.tsaitgaist.infothen it would be 4xAAA/AA (3xAA will only work if fully charged)
the other idea would be :
0.7-4.5 --- VREG 5V --->|----+
|
+--- VREG 3.3V
|
USB 5V ---------------->|----+
or another nice idea (like the arduino does for the 5v) :
BATT --- VREG 3.3V ---+
|
FDN304 -- 3.3V
|
VUSB --- VREG 3.3V ---+
as you wish,
