| X-NUCLEO-IKS01A3: MEMS Inertial and Environmental Multi sensor shield |
| ##################################################################### |
| |
| Overview |
| ******** |
| The X-NUCLEO-IKS01A3 is a motion MEMS and environmental sensor expansion board |
| for the STM32 Nucleo. It is equipped with Arduino UNO R3 connector layout, and |
| is designed around the LSM6DSO 3D accelerometer and 3D 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 Description |
| ******************** |
| |
| X-NUCLEO-IKS01A3 provides the following key features: |
| |
| - LSM6DO MEMS 3D accelerometer (±2/±4/±8/±16 g) and |
| 3D gyroscope (±125/±250/±500/±1000/±2000 dps) |
| - LIS2MDL MEMS 3D magnetometer (±50 gauss) |
| - LIS2DW12 MEMS 3D accelerometer (±2/±4/±8/±16 g) |
| - LPS22HH MEMS pressure sensor, 260-1260 hPa absolute digital output barometer |
| - HTS221 capacitive digital relative humidity and temperature |
| - STTS751 Temperature sensor (-40 °C to +125 °C) |
| - DIL24 socket for additional MEMS adapters and other sensors (configurable in I2C or SPI) |
| - I2C sensor hub features on LSM6DSO available |
| - Compatible with STM32 Nucleo boards |
| - Equipped with Arduino UNO R3 connector |
| - RoHS compliant |
| - WEEE compliant |
| |
| Hardware Configuration |
| ********************** |
| |
| X-NUCLEO-IKS01A3 board connects the various devices on two separate I2C bus: |
| |
| - LIS2DW12 and LSM6DO are on I2C2 |
| - LIS2MDL, LPS22HH, HTS221 are STTS751 are on I2C1 |
| |
| X-NUCLEO-IKS01A3 board can be configured in two different ways: Mode 1 and Mode 2 |
| |
| |
| Mode 1: Standard Mode |
| ===================== |
| |
| In standard I2C mode the two buses are connected together. As a consequence, all devices on the shield |
| reside on the same I2C bus and are accessible from the main board through I2C bus. |
| |
| The jumper configuration to activate this mode is: |
| |
| - JP7 => 1-2, 3-4 (I2C1 = I2C2, I2Cx=GND) |
| - JP8 => 1-2, 3-4 (I2C1 = I2C2, I2Cx=GND) |
| |
| |
| Mode 2: SensorHub Mode |
| ====================== |
| |
| In SensorHub mode LSM6DSO and LIS2DW12 are connected to I2C2 and are accessible from the main board. |
| All the other devices are connected to LSM6DSO master through I2C1. |
| |
| The jumper configuration to activate this mode is: |
| |
| - JP7 => 2-3 (I2C1 = I2Cx) |
| - JP8 => 2-3 (I2C1 = I2Cx) |
| |
| More information about X-NUCLEO-IKS01A3 configuration modes can be found in the |
| `X-NUCLEO-IKS01A3 user manual`_ |
