2.1.4. Setting Jumpers
You configure your board to match the needs of your application by setting
jumpers. A jumper is the simplest kind of electric switch. It consists of two
metal pins and a small metal clip (often protected by a plastic cover) that
slides over the pins to connect them. To “close” a jumper you connect the
pins with the clip.
To “open” a jumper you remove the clip. Sometimes a jumper will have three
pins, labeled 1, 2 and 3. In this case you would connect either pins 1 and 2
or 2 and 3.
The jumper settings are schematically depicted in this manual as follows.
