Mode 3: DIL 24 plus ISM330DHCX I²C sensor hub (all sensors, not DIL 24)
In sensor hub I²C mode, the ISM330DHCX and the DIL 24 adapter are connected to an external main board by
an I²C bus; all other devices are slaves of the ISM330DHCX via I²Caux.
The board configuration is:
•
JP7: 2-3 (I²C1 = I²Cx)
• JP8: 2-3 (I²C1 = I²Cx)
• DIL24 adapter (to I²C2): SB16, SB21
• Not mounted: SB6, SB10, SB12, SB14, SB18, SB19, SB20, SB22

In sensor hub I²C mode, the ISM330DHCX and the DIL 24 adapter are connected to an external main board by
an I²C bus; all other devices are slaves of the DIL 24 adapter via I²Caux, except IIS2DLPC .
The board configuration is:
•
JP7: 2-3 (I²C1 = I²Cx)
• JP8: 2-3 (I²C1 = I²Cx)
• DIL24 adapter (to I²C2): SB12, SB19
• Not mounted: SB6, SB10, SB14, SB16, SB18, SB20, SB21, SB22
