The ThunderBoard-React is a cloud-connected, Bluetooth Smart-enabled, sensor-driven platform that enables customers to demo, evaluate, and develop their own unique applications.

It leverages Silicon Labs’ BGM111 Bluetooth Smart module as a wireless system-on-a-chip (SoC) to collect to various sensor data and deliver it to the cloud through Bluetooth Low Energy (BLE) enabled iOS/Android mobile apps. This document provides an overview of the kit including hardware, software application, cloud platform and mobile app. It also contains instructions and guidelines to evaluate the simplicity of adding Bluetooth to your project to connect to the cloud.

  • Low-cost, Bluetooth Smart solution that collects and delivers data to the cloud
  • Hardware includes BGM111 Bluetooth Smart module linked to sensor inputs
  • ThunderBoard React connects to BLEenabled iOS/Android mobile apps
  • Apps connect to a cloud-based multi-client, real-time synchronization database

ThunderBoard-React is a low-cost, BLE solution that collects and delivers data to the cloud.

The ThunderBoard-React is a great demonstration and evaluation tool to easily add BLE connectivity to a sensor or actuator application. The mobile app seamlessly communicates between the ThunderBoard and the cloud database to visualize sensor data collected or control the LED states on the ThunderBoard-React hardware. Individual components of the ThunderBoard-React can be easily integrated and modified in order to add BLE-to-cloud connectivity for a user’s particular application.
