How to Power HC 05 using 2 -3.3 v lithium cell battery.
Hc05 is not working when I connect it with the 2-3.3v cell battery.
I have checked the total voltage .,=6.68v
But Hc 05 is not responding.
So I read the data sheet of hc05 ,in that it says that the operating voltage of hc05 is between 3.3v. To 6v .
I gived the voltage above 6v .
So I decided to connect a 2v led series to hc05 then the Hc 05 will get voltage nrar 4.3 or grater.
I didn't checked it practicaly .
If you know Any thing about that please help me.

One rechargeable Li-Ion of 4.2 Volt when fully charged, maybe? That controller doesn't work below 3.3 Volt is then a protection against cell deep discharge.

What is HC 05, I found a bluetooth module with that model number, however the datasheet says says 1.8 - 3.3 volts?

er, 1.8V to 3.6V it says.

Freescale 68HC05, I suppose

Yes it should be a Bluetooth module. In arduino compatibility kind of. I think its specs say 3.3V input but I remeber working on it with 5V without burning it. Anyway the logic levels for the uart are 3.3V and won't do that good with 5V. And your LED "power supply" won't be able to handle the current consumption, I fear. I guess you're talking to that thing somehow, just look if you have any power pins on that.
