Description

The STEVAL-IDI004V2 wireless bridge

evaluation kit is an Internet of Things (IoT) Home

Bridge which supports the Wi-Fi, Sub-GHz,

Bluetooth and NFC communication protocols.

The device is suitable for various smart home,

smart city and industrial applications.

The system uses an STM32F103 microcontroller

as a bridge between the various communications

modules. The Wi-Fi, Bluetooth and Sub-GHz

certified modules are connected through a UART

interface to the STM32 microcontroller. The NFC

transceiver module is connected through an SPI

interface.
