Prepare the header strip:Cut the strip to length if necessary. It will be easier to solder if you insert it into a breadboard - long pins down |
|
|
Add the breakout board:Place the breakout board over the pins so that the short pins poke through the breakout pads |
|
|
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 Antenna & Battery
A battery and antenna is required! If you have a uFL FONA, a uFL->SMA cable may be required to connect the antenna. Use any Lipoly or LiIon 3.7V/4.2V battery
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. FM radio does work without a SIM but of course you cannot send or receive texts, calls, etc!|
|
The SIM card holder is on the back. 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 antenna |
|
|
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 |
