FINISHING UP

After youýre done putting down the PLCC socket, all that should be left to do is mount and solder the through-hole connectors. Double check everything and then use a solder flux solvent to clean your board. After the Ethernet Development Board dries, you should have something like you see in Photos 12 and 13.

GOOD JOB

Sit back and marvel at the work youýve just done. In your hands you have a fully functional Ethernet engine backed by the most powerful flash-memory microcontroller in the Microchip arsenal.
