UM3239 User manual Getting started with the X-NUCLEO-IKS4A1 motion MEMS and environmental sensor expansion board for STM32 Nucleo Introduction 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 STEVAL- MKE001A, which hosts the Qvar swipe electrodes.
STM32 Nucleo boards (visit www.st.com for further information). Figure 2. X-NUCLEO-IKS4A1 plugged on an STM32 Nucleo board X-NUCLEO-IKS4A1 must be connected on the matching pins of any STM32 Nucleo board with the Arduino UNO R3 connector. Note:...
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...
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.
LIS2DUXS12 and SHT40AD1B remains connected to the main bus "uC_I2C" coming from the external board. The board configuration is: • J4: 5-6 (HUB2_SDx = SENS_SDA) • J5: 5-6 (HUB2_SCx = SENS_SCL) Figure 4. X-NUCLEO-IKS4A1 LSM6DSO16IS I²C sensor hub UM3239 - Rev 1 page 5/23...
J5: 9-10 (DIL_SDx = SENS_SDA) Figure 6. X-NUCLEO-IKS4A1 DIL24, I²C sensor hub (all sensors) Mode 5: LSM6DSO16IS as Qvar controller In this configuration, it is possible to use the equipped Qvar swipe electrode (by plugging it on JP6 and JP7 connectors) through the LSM6DSO16IS.
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.
As there are a few different interrupt signal assignments for DIL24 pins, the appropriate pin can be selected using the J2 header. Related links Please visit the ST website to find other available sensors Connectors Table 4. Arduino R3 UNO connectors...
