| X-NUCLEO-IKS02A1: MEMS Inertial and Environmental Multi sensor shield |
| ##################################################################### |
| |
| Overview |
| ******** |
| The X-NUCLEO-IKS02A1 is a motion MEMS expansion board for the STM32 Nucleo, |
| fitting the requirements of industrial applications. |
| It is equipped with Arduino UNO R3 connector layout, and |
| is designed around the ISM330DHCX 3-axis accelerometer and 3-axis gyroscope, |
| the IIS2MDC 3-axis magnetometer, the IIS2DLPC 3-axis accelerometer and |
| the IMP34DT05 digital microphone. |
| |
| The X-NUCLEO-IKS02A1 interfaces with the STM32 microcontroller via the I2C pin, |
| and it is possible to change the default I2C port. |

| Hardware Description |
| ******************** |
| |
| X-NUCLEO-IKS02A1 provides the following key features: |
| |
| - ISM330DHCX MEMS 3D accelerometer (±2/±4/±8/±16 g) and |
| 3D gyroscope (±125/±250/±500/±1000/±2000 dps) |
| - IIS2MDC MEMS 3D magnetometer (±50 gauss) |
| - IIS2DLPC MEMS 3D accelerometer low power (±2/±4/±8/±16 g) |
| - IMP34DT05 MEMS digital omnidirectional microphone (-26 dBFS, ±3 dB sensitivity) |
| - DIL24 socket for additional MEMS adapters and other sensors (configurable in I2C or SPI) |
| - I2C sensor hub features on ISM330DHCX available |
| - Compatible with STM32 Nucleo boards |
| - Equipped with Arduino UNO R3 connector |
| - RoHS compliant |
| - WEEE compliant |
| |
| Hardware Configuration |
| ********************** |
| |
| X-NUCLEO-IKS02A1 board connects the various devices on two separate I2C bus: |
| |
| - IIS2DLPC and ISM330DHCX are on I2C2 |
| - IIS2MDC is on I2C1 |
| |
| X-NUCLEO-IKS02A1 board can be configured in two different hardware modes, Mode 1 and Mode 2, |
| using the JP7/JP8 jumpers to modify to what the I2C1 bus connects to. |
| |
| |
| 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 mcu. |
| |
| 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 ISM330DHCX and IIS2DLPC are connected to I2C2 and are accessible from the main board mcu. |
| Instead, the IIS2MDC device is connected only to ISM330DHCX sensor through its SCx/SDX (I2Cx) pins. |
| |
| The jumper configuration to activate this mode is: |
| |
| - JP7 => 2-3 (I2C1 = I2Cx) |
| - JP8 => 2-3 (I2C1 = I2Cx) |
| |
| More information about X-NUCLEO-IKS02A1 configuration modes can be found in the |
| `X-NUCLEO-IKS02A1 user manual`_ |
