Overview
The
is powered via a standard 3.3 V supply through the
connector.
The figure below shows the component placement on the board.

The
interfaces with the main board via an I²C interface along with some GPIO pins for
interrupts. A DIL 24-pin socket is available for additional MEMS adapters and other sensors.
The I²C sensor hub features on the
are also available by using solder bridges.
The expansion board mounts an LDO to generate 1.8 V for all the MEMS sensors. A level shifter between 1.8
V and 3.3 V translates all the signals between the sensors and the main board. Two LEDs and one switch are
available on the board as the user interface.
