IceTube Clock mainpcb from Xmas icetube Rev D. Modified component placement, trace width, and routing. Removed GPS battery connection pad. Added component values to top silkscreen. Improved ground-plane coverage. Added C12 bypass on IC5 (LM317), changed R4 from 5.6K to 10K, improved component value silkscreen. Improved ground and power trace width, increased Awake trace width, improved ground plane cutout for battery holder. Increased trace width for segments 1 and 9, increased DQ trace with for IC4 temp sensor. Changed IC3 footprint to TO-220 vertical which supports both footprints (78L05). Changed R4 footprint to a smaller 0204V vertical footprint Increased AC1 and AC2 trace width to support 85 mA current with less voltage drop. Revision 2.2
