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 Uno

connectors.

–

reset (GPIO0-y) pin, routed from each satellite connector to the GPIO expander

device.

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.
