Getting started with the X-NUCLEO-IKS01A3 motion MEMS and environmental
sensor expansion board for STM32 Nucleo
Introduction
The X-NUCLEO-IKS01A3 is a motion MEMS and environmental sensor evaluation board system.
It is compatible with the Arduino UNO R3 connector layout and features the LSM6DSO 3-axis accelerometer + 3-axis
gyroscope, the LIS2MDL 3-axis magnetometer, the LIS2DW12 3-axis accelerometer, the HTS221 humidity and temperature
sensor, the LPS22HH pressure sensor, and the STTS751 temperature sensor.
The X-NUCLEO-IKS01A3 interfaces with the STM32 microcontroller via the I²C pin, and it is possible to change the default I²C
port.

Hardware requirements
The X-NUCLEO-IKS01A3 is designed to be used with STM32 Nucleo boards (visit www.st.com for further
information).
Figure 2. X-NUCLEO-IKS01A3 plugged on an STM32 Nucleo board
The X-NUCLEO-IKS01A3 must be connected on the matching pins of any STM32 Nucleo board with the Arduino
UNO R3 connector.
Note:
X-NUCLEO-IKS01A3 components are ESD sensitive and, as the board has male/female pass-through
connectors, it is important to handle it with care to avoid bending or damaging the pins.

WEEE compliant
Each device has a separate power supply to allow power consumption measurement of every sensor.
The expansion board is power supply compatible with STM32 Nucleo boards: it mounts an LDO to generate 1.8 V
for all the MEMS sensors except for the STTS751, which is supplied by a separate LDO generating 2.5 V.
All signals between the sensors and the main board are translated by a level shifter.

Default solder bridge configuration
The user can configure several aspects of the X-NUCLEO-IKS01A3 through several solder bridges which can be
left open (not mounted) or closed (mounted) to configure different hardware settings.

The LSM6DSO has an I²C sensor hub which allows it to behave as the I²C master for other slave devices
connected via an I²Caux bus. Various configurations are possible for different I²C bus connections with or without
the LSM6DSO sensor hub.
Mode 1: standard I²C bus connection (all sensors)
In standard I²C mode, all devices are connected to an external main board via the same I²C bus.
The board configuration is:
•
JP7: 1-2, 3-4 (I²C1 = I²C2, I²Cx=GND)
•
JP8: 1-2, 3-4 (I²C1 = I²C2, I²Cx=GND)

Sensor current consumption measurement
The X-NUCLEO-IKS01A3 expansion board is equipped with jumpers which allow separate current consumption
measurement for each sensor.
To measure current consumption, connect an ammeter to the appropriate jumper.
Note:
As the sensors have very low current consumption, you should set a suitable range and use an ammeter with
low burden voltage.

Adapter board for DIL24 socket
An additional sensor can be connected as an adapter board to J1 DIL24 socket.
As there are a few different interrupt signal assignments for DIL24 pins, the appropriate pin can be selected using
the JP6 header.
