Hi,

Does anyone know if the GP2X Battery Input can accept 3.3V ? If possible , I can connect my Li-Ion and use a LDO as power input.

Regards,

Hilary

Yes, search for my thread called "3 cell battery test" I connected 3 AA batteries to the battery compartment.

Squidge used a bench supply and discovered that 3.7 volts is about the optimum for the internal DC-DC regulation, so 3.3 would be much better than 2.4-2.8 that the AA batteries give us.
