If you're a bit stuck with a SparkFun product and need some help, the friendly SparkFun Tech Team over the water in Colorado are the best people to ask - they know their products better than anyone on the planet!
You can email them at techsupport@sparkfun.com.
You can also find all of the relevant setup, assembly and code links at the bottom of each of our SparkFun product pages as well.
If you believe a SparkFun product is faulty we usually ask you to check with the SparkFun Tech Team first, and if they can't get the hardware/software working as expected, just let us know and we'll make sure you're looked after.
