Before mounting the shield, verify that the following jumpers in particular are in
the ​ ​ correct ​ ​ positions ​ ​ as ​ ​ shown ​ ​ in ​ ​ the ​ ​ figure ​ ​ below:
Figure ​ ​ 3-1: ​ ​ correct ​ ​ jumper ​ ​ positions ​ ​ for ​ ​ chipKIT ​ ​ board.
J15: jumper should be in the ‘EXT’ position. This allows the shield to be powered
off ​ ​ of ​ ​ the ​ ​ chipKIT ​ ​ board’s ​ ​ external ​ ​ 12 ​ ​ V ​ ​ supply ​ ​ port ​ ​ instead ​ ​ of ​ ​ the ​ ​ USB ​ ​ port.
JP4/JP5: jumpers should be in the ‘AN’ positions to disconnect the I2C bus from
the ​ ​ analog ​ ​ sensor ​ ​ ports.
