Wireless Bridge 868 MHz

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.
