Getting started with the X-NUCLEO-IKS4A1 motion MEMS and environmental
Introduction
The
X-NUCLEO-IKS4A1
is a motion MEMS and environmental sensor evaluation board kit consisting of the main board
NUCLEO-IQS4A1, which hosts the motion MEMS and environmental sensors, and the detachable add-on board
MKE001A, which hosts the Qvar swipe electrodes.
It is compatible with the Arduino UNO R3 connector layout and features the
accelerometers, the
LIS2MDL
sensor, the
SHT40AD1B
humidity and temperature sensor, and the
The
X-NUCLEO-IKS4A1
interfaces with the STM32 microcontroller via the I²C pin or, for external sensors mounted on DIL24
adaptor, SPI Pins.

Page 3: System Requirements
UM3239 System requirements System requirements To complete the system setup, you need: ® • a Windows (7, 8, 10) PC • a USB type A to mini-B USB cable to connect the STM32 Nucleo to the PC • board firmware and software package (X-CUBE-MEMS1) installed on the user PC UM3239 - Rev 1 page 3/23... -
Page 4: Hardware Description
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-IKS4A1 through several solder bridges which can be left open (not mounted) or closed (mounted) to configure different hardware settings. -

LSM6DSV16X (U4) SB17 ADD=D5h SB15 ADD=D7h Sensor current consumption measurement The X-NUCLEO-IKS4A1 expansion board is equipped with OR resistors that allow separate current consumption measurement for each sensor. To measure current consumption, connect an ammeter to the appropriate pads. Note: As the sensors have very low current consumption, you should set a suitable range and use an ammeter with low burden voltage. -
