JHDR 1 + 2 + 3



3 position jumper header

The jumper headers allow you to configure the communication pins on the Arduino that are used by GinSing. By default, the board and software is configured to utilize pins 2, 3, and 4, but you can change these in any combination to ( 10, 11, and 12 ) if you are using other shields that might use these pins. In software you specify what pins the GinSing hardware will use. The headers should be placed according to the alignment on the board. Place the shorter leads of the header into the board - the longer leads are used for the jumpers.
