Developer kit accelerates IoT sensing connectivity

Designed to connect wireless sensor nodes to mobile devices and the cloud, the Silicon Labs Thunderboard React developer kit features a battery-powered, sensor-rich demonstration board with Bluetooth low energy technology and an ARM Cortex-M4 processor for IoT connectivity. There are also open-source design files and software for mobile apps running on Android and iOS devices. All hardware schematics, firmware, mobile apps and cloud software are available at no charge to developers.

The on-board sensors measure motion, light and environmental conditions, and this real-time sensor data is transmitted to the cloud over a Bluetooth connection. An intuitive mobile app displays the data on smartphones and tablets while enabling the user to control the board.

No RF expertise is required to develop wireless sensing applications. Developers can use the company’s wireless development tools, and the pre-certified Bluetooth low energy module to minimises the time and effort required for global wireless certifications.

The Thunderboard React kit includes BGM111 globally pre-certified Bluetooth low-energy module, the Si7021 relative humidity and temperature sensor, the Si1133 UV index and ambient light sensor, a six-axis gyro/accelerometer and Hall effect position sensor.

Energy-efficient components on the board enable developers to create IoT nodes powered by small coin-cell batteries. The company has optimised the provided firmware and mobile app to take advantage of the power-saving features of the board components. The components can be integrated and modified to enable Bluetooth-to-cloud connectivity for a particular IoT application.

An optional Pinewood Derby-style car kit can be ordered to use with Thunderboard React, to demonstrate real-life capabilities possible. The board fits into the body of the derby car and displays acceleration, speed, distance, inertia, proximity, humidity and temperature.
