Quick question about powering the SM5100B gprs/gsm from sparkfun :D

Hi guys i just want to ask you if i could use a 6v battery to power it up, the shield.

I saw in the schematics it has a power regulator so would it be ok if i use a 6v battery???
The ones who have already bought and used this shield how did you powered it up?

Thanks :smiley:

No one ?
