BUG FIX AND ENHANCEMENTS:
1. CON2 GND CONNECT TO BOARD GND
2. LED LAYOUT LIBRARY NOT SAME AS ACUTAL COMPONENT USED. NEED TO CHANGE
DIRECTION 180 DEGREES
3. C42 NEED TO CONNECT PIN 2 AND 3 TOGETHER
4. AGND AND DGND CONNECTED
5. ADD SPEED LED CONTROL CIRCUIT, DUE TO DM9161B DESIGN
6. ADD EXTERNAL 1.8V LDO FOR INPUT TO CENTER TAP OF TRANSFORMER TO
REDUCE HEAT DISSIPATION BY CHIP
