General Info

Part Number: 10684

--68.157.6.30 19:49, 11 March 2010 (UTC)== PCB Layout To-Do List ==

1. Create footprint for RJ-45 connector to enable mounting from top or bottom side of PCB -Done
2. Move RJ-45 connector to the right and down at least 400-500 mils -It has been moved please verify clearance with current position
3. Move PoE module down another 100-150 mils for clearance -Done
4. Replace 10 pin and 14 pin headers with surface mount type (see datasheets below)
5. Move expansion headers (10 pin and 14 pin) to align with connectors on audio satellite board (in eDrawings make the body transparent or hidden to see the internal components
6. Move JTAG connector up and to the right side to avoid internal interference
