3.3 Raspberry Pi® 3 Model B+ Board
The Raspberry Pi 3 Model B+ development board runs various distributions of the Linux® operating system, granting open-source software libraries, drivers, and applications to the users. These allow easy interfacing with other devices. The board provides a built-in BLE module for communication with the end nodes and Wi-Fi and Ethernet socket for the cloud connection and communication, favorable for IoT. The RPi 3 B+ has an armv71 processor architecture and will be used in this demo application, as a gateway. A microSD card, which is at least 8 GB in size, is needed for the operating system of RPi and the gateway software.
