LTE CAT-1 Cellular Shield for Arduino

I assembled another board and now the speaker works during voice calls! Previously it hadn't, and I couldn't figure out what it was for the life of me so I just made another one and voila, it works, so I'm assuming it was either the module or some random short underneath the module that I couldn't see.

Anyway, it's a fully-functional and voice-enabled LTE shield and I'm planning on launching a crowdfunding campaign to get this project off the ground!

Hey guys!

I've successfully tested and implemented HTTP and HTTPS commands in the Github library and voice calls work with the exception of the speaker not making any sound for some reason. 

Once I get the speaker working I'll be sure to update documentation, run current consumption tests on it in various modes, and create more tutorials!
