Troubleshooting
Getting started with an advanced development board like the Edge can be difficult. Especially with this process it is easy to get off into the weeds. The first steps to troubleshooting should always be to carefully re-check the work you've done. Pretend you're explaining what you're doing to your grandmother. If that doesn't work then try checking out the Edge Troubleshooting thread on the SparkFun Forums.
