In the tutorial it only shows the FONA used with the LiPo battery, I guess there is a way to also use the module on a power supply.
What would be the input voltage range that the FONA needs to operate, how much current will the module withdraw at max ? Can I apply that power supply on the LiPo pins directly ? When the micro USB is plugged onto a USB source, does it bypass the battery and provides enough power to the module and operate normally ?
Thanks,
FONA on power supply ?

Re: FONA on power supply ?
the microUSB is only used to charge the battery. You *can* power the FONA directly with 3.4V-4.2V voltage level. Its an odd voltage range (doesn't cover the common 3.3 or 5V) If you want to do that, apply that voltage to VBat and do not plug anything into the microUSB port.

Re: FONA on power supply ?
Thanks for the answer !
What does the *can** implies ? Is there any risk of damaging the module by doing so ?
Also, what is the peak amps consumption of the module ?
Cheers,

Re: FONA on power supply ?
Sorry if I missed this, but since the FONA requires an external battery, can the FONA board also power the arduino project board it's interfaced with?

Re: FONA on power supply ?
No. The board does beak out a 5V line, but that's the 5V from the micro-USB connector used for charging the battery. You could power the rest of your project from there, but it would only work when the microUSB is plugged in.pbo wrote:can the FONA board also power the arduino project board it's interfaced with?

Re: FONA on power supply ?
Thank you for the reply! Darn... I was planning on using the FONA in a portable project (possibly in the menta tin) and 2 batteries would be a bit of a pain, but not impossible of course. Thanks

Re: FONA on power supply ?
Hi, Are we sure there isn't an easy way to share the FONA battery with the rest of the project? In the "New Products" Video on 7/2, unless I'm mistaken, it was mentioned that you could use 1 battery for the whole thing. If not, can you "split" the leads of the battery to go to both boards?
Kind of more difficult to build a portable project if we have to power it with two batteries. Appreciate any input!
Thanks

Re: FONA on power supply ?
Oh, sure - you can use one battery with split leads. You just can't connect the rest of your project to the 5V pin on the FONA.

Re: FONA on power supply ?
Hypothetically, if I get a LiPo battery and permanently plug the FONA usb to a USB source.
This way the FONA will remain ON ? Without worrying about the battery failing.
Thanks,

Re: FONA on power supply ?
Having a LiPo constantly on charge does not harm its lifetime and stability ?

Re: FONA on power supply ?
I didn't say that. I interpreted "without worrying about the battery failing", as "ignoring that part of it". Batteries wear out.

Re: FONA on power supply ?
OK, so better directly input on Vbat the supply voltage without using any LiPo battery nor the build-in USB plug ?

Re: FONA on power supply ?
It's designed to be powered by a 3.7V LiPo battery. If you can find a 3.7V power supply, then that should also work.

Re: FONA on power supply ?
Hi guys, can you specify the power consumption in mA?
If i connect a 3.7V power supply to Vbat how much mA the FONA needs in your max use?
Thanks!
