Stack Alert!

If you want to stack a shield on top of the FONA Shield, you'll want to pick up some stacking headers and use those instead of the plain header shown here!  

Wanna stack? This tutorial shows how to use the plain header to connect to an Arduino. If you want to use stacking headers, don't follow these steps!

Attaching Header

Begin by breaking the 36-pin male header into four pieces: one 10-pin, two 8-pin and one 6-pin. Stick the header into the Arduino sockets with the long pins down.

Place the shield on top so that all the little pins stick out through the matching holes in the shield. It should match up perfectly!

(These photos show a FONA 800 shield, but the overall process is identical for the FONA 808)

And Solder!

Be sure to solder all pins for reliable electrical contact.

(For tips on soldering, be sure to check out our Guide to Excellent Soldering).

You're done! Check your solder joints visually and continue onto the next steps

Attaching Antennas & Battery

A battery and GSM antenna is required to use the Cellular module. If you want to use GPS as well, a passive GPS antenna is also required

Check polarity for the battery!
Snap the uFL connector on, it will click when placed properly

SIM Card

You must insert a SIM card to do anything but the most basic tests. The shield and GPS does work without a SIM but of course you cannot send or receive texts, calls, etc!

The SIM card holder it on the right side of the shield. It holds a very-standard "Mini SIM"
Micro SIMs will not work! Make sure you get a "Mini SIM"

Open by sliding the cover towards the bottom of the shield

Insert the SIM with the gold pads facing up and the notch on the outer corner

Close the hinge down and slide the cover to lock it in place

The SIM should be secure and flat in the holder
