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`_
