1. These interrupt signals are duplicated, but not used, this offers hardware connection flexibility in case of
conflict on MCU interface management when expansion board is used superposed with other expansion
boards, in this case remove 0 ohm resistor from interrupt used and connect 0 ohm resistor in place of “do
not mount” one.
Optional VL6180X satellite board
The VL6180X expansion board allows connecting up to 3x VL6180X satellite boards (see
Figure 2). This allows to develop applications controlling up to 4x VL6180X.
• I2C bus is common with the VL6180X on-board: I2C bus,
• each satellite can be connected through a dedicated connector to be soldered on the
expansion board and has its own:
– interrupt (GPIO1-x) pin, routed from each satellite connector to the Arduino
connectors.
– reset (GPIO0-y) pin, routed from each satellite connector to the GPIO expander
device.
