Crux Product Design has created an IoT sensor node Proof-of-Concept (PoC) that can be seamlessly integrated into the existing form factor of various products to gather user data without influencing the product’s function or user behavior. The ‘Crux Modular Distributed Sensing Platform’ supports a range of applications across medical devices, fast moving consumer goods, UX (user experience) studies, general prototyping of future products, and more.
Powered by the Wafer Level Chip Scale Package (WLCSP) version of the Nordic nRF52840 SoC, the fully customizable IoT sensor node device is intended to be an adaptable, future-proof platform. It is built around a modular concept where a main board contains the highest technology and core functionality, while simpler daughterboards can be used to extend functionality to suit individual applications.
The PoC measures just 10 by 10 mm which was in part achieved due to the 3.5 by 3.6 mm dimensions of the Nordic WLCSP. The PoC can even be reused in a second application, lowering cost, facilitating faster revisions, and keeping waste low in a sustainability-focused environment. The design framework of the PoC allows for ancillary components such as power supplies and sensors to be selected specifically for each application.
