Circuit board heat Trouble. Answered
Full disclaimer, I am still learning and at my current skill level I am essentially following a picture book showing how to hammer a nail then emulating it, Hope that analogy paints the picture correctly. Now for the problem! I have embarked on a journey of growth and learning, in said adventure I took a personal challenge of building something and hopefully learning in the process. Needless to say I did learn, some lessons more painfully than others (soldering Irons are HOT *Sigh*) but I am at an impasse.
You should see attached (hopefully) one schematic and two photos.
The schematic correlates to the board of course.
The next two are of the silkscreen on the board (empty) and the board upon "completion". If you notice in the empty board photo I have drawn your attention to a specific area, the area in question. In this area there seems, during testing, a decent amount of heat build up. Now this may be normal, I do not know. The device calls for the use of three Protected 18650 Lithium Batteries (3.7V I believe). I attempted to do a continuity test with what I thought was under voltage, in hindsight, I'm not sure whether the power cells are in series or parallel so perhaps I was not under? anywho that is when I noticed the heat in that area.
I hope I have illustrated my predicament enough for a solid enough understanding, If not I apologize. Please ask any information you require.
