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.
