MEMS inertial and environmental sensor expansion board for
STM32 Nucleo
Introduction
The X-NUCLEO-IKS01A1 is a MEMS inertial and environmental sensor evaluation board
which can be used to expand the STM32 Nucleo system. It is also compatible with the
Arduino UNO R3 connector layout and is designed around the STMicroelectronics 3-axis
accelerometer plus 3-axis gyroscope (LSM6DS0), 3-axis magnetometer (LIS3MDL),
humidity (HTS221) and pressure (LPS25H) sensors. The X-NUCLEO-IKS01A1 interfaces
with the STM32 MCU via the I
2
C pin, and the user can change the default I
2
C port.
This document details the hardware requirements and board connections for the X-
NUCLEO-IKS01A1 MEMS and environmental sensor expansion board for STM32 Nucleo.

1 Getting started
This section describes the hardware requirements for the X-NUCLEO-IKS01A1 evaluation
board.
1.1 Hardware requirements
The X-NUCLEO-IKS01A1 is an expansion board for use with STM32 Nucleo boards (please
refer to UM1724 on www.st.com for further information). To function correctly, the STM32
Nucleo board must be connected to the X-NUCLEO-IKS01A1 board, as shown in Figure 2.
Figure 2. X-NUCLEO-IKS01A1 mounted on a STM32 Nucleo board
The connection between the STM32 Nucleo and the X-NUCLEO-IKS01A1 is designed for
use with any STM32 Nucleo board or Arduino UNO R3 platform.
When mounting the X-NUCLEO-IKS01A1 on the mainboard:
ensure that all the pins are aligned with their corresponding connector
It is very important to handle both boards carefully during this operation to avoid damaging
or bending the male/female pins and connectors.
ESD prevention measures must also be implemented to avoid damaging any X-NUCLEO-
IKS01A1 board components.
System requirements UM1820
4/14 DocID026959 Rev 1
2 System requirements
Using the Nucleo boards with the X-NUCLEO-IKS01A1 expansion board requires the
following software and hardware:
•a Windows
®
(XP, Vista, 7, 8) PC on which to install the software
•a USB type A to Mini-B USB cable to connect the Nucleo to the PC for installation of
the board firmware package (order code: X-CUBE-IKS01A1). A utility running on the
user's PC will complete the demo. The user’s PC must have the following
characteristics:
– At least 128 MB of RAM
– 40 MB of available hard disk space for the X-CUBE-IKS01A1 firmware package
and relative documentation, available on www.st.com

3 Hardware description
The board allows the user to test the functions of the STMicroelectronics motion MEMS
accelerometer, gyroscope, magnetometer and environmental sensors for humidity,
temperature and pressure.
The devices used on the board are:
– LSM6DS0: MEMS 3D accelerometer (±2/4/8g) + 3D gyroscope
(±245/500/2000dps)
– LIS3MDL: MEMS 3D magnetometer (±4/8/12/16 gauss)
– LPS25H: MEMS pressure sensor, 260-1260 hPa absolute digital output barometer
– HTS221: Capacitive digital relative humidity and temperature sensor
The X-NUCLEO-IKS01A1 also has a DIL24 socket to connect and test additional sensors
(i.e. UVI sensors, other MEMS sensor, etc…).
The sensors are connected on a single bus via I
2
C and each device has a separate power
supply to allow measurement of the power consumption of each single sensor.
3.1 Board block diagram
Figure 3 shows a block diagram of the X-NUCLEO-IKS01A1 board.
Figure 3. X-NUCLEO-IKS01A1 block diagram
3.2 Sensor I²C address selection
Most of the sensors allow selection of the LSB of the I
2
C address by pulling the SD0 pin low
or high. The board has solder bridges to control the SD0 level.
Hardware description UM1820
6/14 DocID026959 Rev 1
3.3 Sensor current consumption measurement
To measure the individual current consumption of each sensor, connect the ammeter at the
appropriate jumper points. Use an ammeter with a low burden voltage and set it to a suitable
range as the sensor current consumption is typically very low.
3.4 Sensor disconnection
To disconnect a sensor, disconnect the I²C bus as well as the power supply. Table 3 will help
you identify the appropriate jumpers and solder bridges.
3.5 DIP24 socket for adapter boards
Sensors can be added via adapter boards connected to the DIL24 socket J1. Please visit
www.st.com to find other sensors that are available.
As there are various interrupt signal assignments to DIL24 pins, the appropriate pin can be
selected using the JP6 header.
