The complete solution collects sensor data and, through a mobile app, seamlessly connects Thunderboard React to a real-time cloud database. The board integrates Silicon Labs’ BGM111 Bluetooth low energy module — an ultra-low-power Bluetooth 4.2 module that includes a 32-bit ARM Cortex-M4 processor — with optical, environmental, and motion sensors. The BGM111 module includes a Bluetooth radio, an antenna, and a Bluetooth low energy software stack, and provides transmit power up to 8 dBm and receiver sensitivity down to -93 dBm for robust RF performance. The BGM111 module communicates via an I²C interface with the board’s sensors: Silicon Labs Si7021 relative humidity and temperature sensor, Silicon Labs Si1133 ambient light and UV sensor, a hall-effect sensor, and a 6-axis motion sensor.


The Thunderboard mobile app can be used to control the LED states on the Thunderboard React hardware and to connect to the cloud database for data visualization. Designers can integrate and modify individual components of the Thunderboard React to add sensor-to-cloud connectivity to tailored applications. The board also includes a 10-pin Mini-Simplicity debug connector that allows designers to develop, program, and debug the firmware application with the hardware via Silabs’ Simplicity Studio.


The Thunderboard React is available as an evaluation board or in a Car Kit, which bundles a model car with the evaluation board. Designers can mount the board on the car, and then measure speed, orientation, and movements of the car through the mobile app.
