One of the breakout boards has an unlabeled GPIO so he was showing me the process of how he identifies and labels the pins.(I am still learning, so I apologize if I get any of the terms wrong.)&amp;nben-USTelligent Community 12https://community.element14.com/challenges-projects/element14-presents/benheck/ben-heck-exclusive/b/blog/posts/how-to-identify-an-unlabeled-gpio-w-felixWed, 16 Dec 2015 20:36:09 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:54e364c0-a858-44ae-b04b-3573effbf590DAB0<p>Nice post.</p><p>&nbsp;</p><p>No matter how much experience you have, tracing pins is just part of the job, both to verify the connections and to establish an initial circuit description.</p><p>&nbsp;</p><p>So I urge you to spend a lot of time doing this procedure on the various boards you have and see if you can start to build up a circuit diagram, at least at the black box level.</p><p>&nbsp;</p><p>We have all started here, so take the time to learn the skill well.</p><p>&nbsp;</p><p>DAB</p><img src="https://community.element14.com/aggbug?PostID=928&AppID=101&AppType=Weblog&ContentType=0" width="1" height="1">
