Devkit Specifications
ThunderBoard Sense
Silicon Labs
The Thunderboard Sense "Inspiration Kit" is the second in the Thunderboard family of development kits, and includes six different sensors (a seventh hall-effect sensor coming soon) that interface with the onboard 2.4 GHz multiprotocolwireless EFR32 SoC. The Thunderboard Sense, which can be powered by a coin cell battery, also comes with a companion Android/iPhone app that allows developers to track sensor data in real-time for cloud-based monitoring and analytics.
