| X-NUCLEO-IKS01A2: MEMS Inertial and Environmental Multi sensor shield |
| ##################################################################### |
| |
| Overview |
| ******** |
| The X-NUCLEO-IKS01A2 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 LSM6DSL 3D accelerometer and 3D gyroscope, the LSM303AGR |
| 3D accelerometer and 3D magnetometer, the HTS221 humidity and temperature sensor |
| and the LPS22HB pressure sensor. |
| |
| The X-NUCLEO-IKS01A2 interfaces with the STM32 microcontroller via the I2C pin, |
| and it is possible to change the default I2C port. |

| |
| Hardware Configuration |
| ********************** |
| |
| X-NUCLEO-IKS01A2 board connects the various devices on two separate I2C bus: |
| |
| - LSM6DL is on I2C2 |
| - LSM303AGR, LPS22HB, HTS221 are on I2C1 |
| |
| X-NUCLEO-IKS01A2 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 LSM6DSL is connected to I2C2 and is accessible from the main board. |
| All the other devices are connected to LSM6DSL 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-IKS01A2 configuration modes can be found in the |
| `X-NUCLEO-IKS01A2 databrief`_ |
