I just need some clarification from Arduino folks (preferably the person who actually designed the Ethernet Shield 06) as to the discrepancy where the schematic and board eagle files shows R1 and C3 but seems to not be present in the actual board.
This is the schematic
This is the board layout. I highlighted the area where R1 and C3 are supposed to be located
This is the actual board, notice how it is different from the posted eagle file?
this is another picture from http://arduino.cc/en/Main/ArduinoEthernetShield
, which shows the solder pads, but still no R1 and C3 present.
Does this mean in the schematic, R1 and C3 was removed?
