A premium development tool for sensor hub applications
Introduction
The STEVAL-IDI001V1 is a premium development tool for “sensor hub like” applications. It has a small
form factor (4x4cm) and is based on the STM32F439 microcontroller (Cortex-M4) and a wide range of
STMicroelectronics sensors. It is particularly designed around:
Environmental sensors:
humidity and temperature sensor (HTS221)
absolute pressure sensor(LPS25HB)
UV index sensor (UVIS25)
iNEMO®inertial measurement unit:
3D accelerometer + 3D gyroscope + 3D magnetometer (LSM9DS1)
Proximity, ambient light sensors and VCSEL light source:
Three-in-one smart optical module (2x VL6180X)
Acoustic sensors:
Digital MEMS microphone array (4x MP34DT01)
The STEVAL-IDI001V1 is also equipped with 8 MB external RAM for complex processing algorithms, a
microSD card expansion for data storage and a Micro-USB connector to communicate with an external
device and for power supply.
Figure 1: STEVAL-IDI001V1
The STEVAL-IDI001V1 offers a set of GPIO expansions that can be used to interface with external
hardware. For instance, the STEVAL-IDI001V1-Exp, shown in Figure 2: "STEVAL-IDI001V1 connected
to the STEVAL-IDI001V1-Exp" and provided with the STEVAL-IDI001V1 kit, allows the interoperability
between STEVAL-IDI001V1, STM32-Nucleo and X-NUCLEO Expansions. Expansion boards can be
connected either via Arduino or Morpho connectors. This document provides detailed hardware
requirements and board descriptions.

1 Getting started
This section describes the hardware requirements for the STEVAL-IDI001V1 evaluation
board.
1.1 Hardware requirements
The STEVAL-IDI001V1 can be used as a standalone module or connected to the STEVAL-
IDI001V1-Exp. To function correctly, the STEVAL-IDI001V1 board must be connected to
the STEVAL-IDI001V1-Exp board as shown in the figure below. With this configuration, the
developer can take advantage of the X-NUCLEO expansion boards, connecting them
either via Arduino or Morpho connectors. The STEVAL-IDI001V1 expansion also allows
interfacing the demo board with an STM32Nucleo, using the STEVAL-IDI001V1 as a
sensor hub.
Figure 2: STEVAL-IDI001V1 connected to the STEVAL-IDI001V1-Exp
The STEVAL-IDI001V1 must be connected to the mainboard with care, ensuring that all the
pins match those on the opposite connector. As the board has male/female pass through
connectors, you must handle it carefully to avoid damage or bending the pins. Components
mounted on the STEVAL-IDI001V1 are ESD sensitive, so you must implement the
necessary precautionary measures when handling the board.

System requirements
UM1988

DocID028657 Rev 1
2 System requirements
Using the STEVAL-IDI001V1 board requires the following software and hardware:
a Windows PC (XP, Vista, 7, 8) to install the software package
a USB type A to Micro USB cable to connect the STEVAL-IDI001V1 to the PC for
power supply and communication
STM32 Composite driver (VCP+Audio) contained in the Driver folder of the package
Audio recording software to record and save the audio stream. Any free or commercial
audio recording software like Audacity (http://audacity.sourceforge.net/) can be used
ST-Link V2 or STM32-Nucleo board, with SWD cable adapter and ST-Link Utility for
firmware download (http://www.st.com/web/en/catalog/tools/PF258168)
A utility running on the user PC will complete the demo. The PC must have the following
characteristics:
At least 128 MB of RAM
50 MB of hard disk space available
The STEVAL-IDI001V1 firmware and related documentation is available on www.st.com.

3 Hardware description STEVAL-IDI001V1
This board offers to the user an evaluation kit for STMicroelectronics motion MEMS
(accelerometer, gyroscope, magnetometer), environmental sensors (humidity, temperature,
pressure and UV index), optical module (proximity and ambient light) and digital
microphone array. The high processing power of the STM32F439 allows the user to
implement embedded sensor fusion algorithms. The obtained data can be stored in a
microSD card through the adapter mounted on the board via USB, or a different interface if
the proper expansion board is plugged on the STEVAL-IDI001V1-Exp. The main
components mounted on board are::
LSM9DS1: MEMS 3D accelerometer (±2/±4/±8g) + 3D gyroscope
(±245/±500/±2000dps) + 3D magnetometer (±4/±8/±12/±16 gauss)
LPS25HB: MEMS pressure sensor, 260-1260 hPa absolute digital output barometer
HTS221: Capacitive digital relative humidity and temperature sensor
UVIS25: Ultraviolet radiation index sensors
2x VL6180X: range and ambient light sensor, IR emitter
4x MP34DT01: ultra-compact, low-power, omnidirectional, digital MEMS microphone
STM32F439IIH6: high performances MCU ARM®Cortex™-M4F @ 180MHz with
256KB of embedded SRAM
External SRAM: 8MB of external SRAM
All the sensors, excluding the microphones, are connected to a single I²C bus. The
LSM9DS1 and the LPS25HB can also be connected via SPI, thanks to a hardware switch
which is programmable through the microcontroller. The four microphones are instead
connected to four different GPIOs.

3.1 Board block diagram
Figure 3: STEVAL-IDI001V1 block diagram
3.2 Sensor I²C address selection
Most of the sensors allow selection of the LSB of the I²C address by pulling the SA0 pin low
or high.
Table 1: SA0 level control

Default
LSM9DS1 (U8)
PI9
Low
LPS25HB (U12)
PI10
Low
UVIS25 (U19)
PI8
Low
The proximity and ambient light sensors (VL6180x) have a default I²C address, but can be
modified via I²C in order to manage more than one sensor on the same bus.
3.3 Sensors interface switch
The 9 axes IMU (LSM9DS1) and the pressure sensor (LPS25HB), can be acquired through
the SPI or I²C interfaces. To make these alternatives available, an analog switch (U17) can
be configured by firmware. By manipulating the proper selection pin, the developer can
interact with those sensors via SPI or via I²C.

3.4 Audio acquisition
A digital MEMS microphone can be acquired using different peripherals, such as SPI, I²S or
GPIO. It requires an input clock and it outputs a PDM stream at the same frequency. This
PDM stream is further filtered and decimated in order to be converted in PCM format, the
main standard for audio transmission. In the STEVAL-IDI001V1 board, four microphones
are connected to four different GPIOs. A precise clock signal is generated by a timer and
provided to the microphones; the DMA operates at the same frequency. By configuring an
analog switch (U18) via firmware, you can acquire four external microphones instead of the
four on-board ones on the same GPIOs. You can also acquire up to eight additional
external microphones through the J9 connector.

4 Hardware description - STEVAL-IDI001V1-Exp
STEVAL-IDI001V1-Exp is an expansion board that allows the interoperability between
STEVAL-IDI001V1, STM32-Nucleo and X-NUCLEO expansions. Expansion boards can be
connected either via Arduino or Morpho connectors. The hardware is compatible with
STM32-Nucleo and it is possible to use the STEVAL-IDI001V1 as a sensor-Hub by
connecting an STM32-Nucleo to the STEVAL-IDI001V1-Exp. The STEVAL-IDI001V1-Exp
is equipped with Morpho connectors (upward and downward) and Arduino UNO R3
connectors (upward) to accommodate multiple boards. It is also equipped with STEVAL-
IDI001V1 connectors. Three different power supply options are available: STM32-Nucleo (if
plugged), STEVAL-IDI001V1 USB or an external 5 V power supply.
