INSTALLING THE BYPASS CAPACITORS

Now that youýve got the hang of soldering in SMT land, go ahead and install the 0.1-ýF bypass capacitors (C11, C12, and C15) on the Ethernet side of the Ethernet Development Board. As you can see in Photo 5, there are only three 0.1-ýF bypass capacitors on the Ethernet side of the Ethernet Development Board. Just in case you havenýt noticed, the SMT caps are not marked, so be careful not to confuse parts as you prepare to solder them down. Before you complete the assembly of the smaller SMT components on the Ethernet side, letýs talk about why those components are there.

Photo 5ýThese caps are great practice. Youýll need it for the other side of the Ethernet Development Board.
