A premium development tool for sensor hub applications
Introduction
The STEVAL-IDI00
1V1 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 acceler 3D gyr 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.

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
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.
