External Expansion Board

The Expansion Board allows easy prototyping of third party sensors or custom sensing solutions with Shimmer.

*Must be connected to the Shimmer platform to be operational

The Expansion Board enables an analog sensor, a digital output sensor, a Serial UART, or a Parallel Bus Interface to connect to Shimmer. The Expansion board is connected to Shimmer via the external connector pin, and is positioned outside the Shimmer enclosure.

The Expansion Board enables users to incorporate additional functionality to the Shimmer providing an outlet to develop their specific application to their own user requirements.
