====== EAGLE Layout Guidelines ======
  * Avoid all acute angles
  * Prefer entering pads perpendicularly
  * Avoid ''+''-style intersections
  * Provide adequate polygon isolation
  * No 90 degree trace turns (bevel corners)
  * Avoid long "antenna"-shaped polygon pours
  * Avoid ground plane islands
  * Check for ground plane choke points
  * Always use vector fonts
  * Use thermals whenever possible
