Libelium GPRS module for Arduino power PROBLEMS!!!

I am having a horrible experience with this module.http://www.libelium.com/squidbee/index.php?title=New_GPRS_module_for_Arduino_(Hilo_-_Sagem) Can this module be used with batteries as a remote mobile device?
The GSM/GPRS module's datasheet says it needs 3.3V and 2.2A - with these requirements, is it possible to make this run off 4 AA batteries + the arduino? or even 8 AA batteries pushing 6V?
So far I have not been getting good results with respect to power usage. In fact it shuts off even with the capacitor installed. Are there any workarounds?

I am considering changing my application to use the telit module from sparkfun - any powering experiences from this one?

Hello frazras!!
Voltage isn't the problem, the current is the problem!. You need al least 2A to make that the GPRS module works perfectly.

I was the same problem days ago and I could solve it with a capacitor. To be exact, a 470uF capacitor located between 5V and GND. With this extra current, you can power arduino with 8 or 9 V, maybe less..But if you want to use 6V you can try with a bigger capacitor.

Try it and tell us your experience ;). Good luck!!

The peak currents of over 2A required by GSM modules are very short, the average currents when offline should be under a couple of milliamps or so. A capacitor should do it, providing it can supply the peak current for the 477uS required...

www.tdc.co.uk have a webshop with Cinterion modules and boxed modems, the boxed modems (called 'terminals') are easier to power from ordinary 12V power supplied.

Hey! We might have a solution for you guys! The supplying is not a problem and you can even supply the GSM Shield from the LiPol battery. Please check ​Váš parťák ve světě tvoření | HWKitchen.cz
