Description: Small breakout board for the Crystal LAN CS8900A from Olimex. Contains all the necessary hardware to implement an Ethernet interface including the isolation transformer and LINK/STATUS LEDs.
The Crystal LAN IC has 100 pins and two dots on it. The smaller of the two dots is the pin 1 indicator which should also have a notched corner. Pin numbers increase in a counter-clock-wise direction. CON1_1 in the schematic corresponds to silkscreen '1'. CON2_1 in the schematic corresponds to silkscreen '17'.
