A.2 Jumpers
Setting jumpers
The board has a number of jumpers that allow you to configure your system to suit your appli
cation. A jumper is a kind of electric switch. Through setting jumpers, you can configure your
card to match the needs of your application.
A jumper consists of two metal pins and a small metal clip (often protected by a plastic
cover). To connect the pins, lid the pin with the clip. To disconnect a jumper, remove the clip.
Some jumpers have three pins, labeled 1, 2 and 3. In this case you can connect either pins 1
and 2 or 2 and 3.
