The Notecard is a device-to-cloud data pump that reduces the complexity of building connected solutions with Wi-Fi. As an embeddable system on module (SoM), the Notecard can be used with any microcontroller for both greenfield and retrofit projects using your own design, or one of our custom designed Notecarriers.
The Notecard WiFi is a lower-cost version of the cellular-based Notecards for 2.4 GHz Wi-Fi only, and is API-compatible with the cellular-based Notecards. The Notecard WiFi also supports location tracking via Wi-Fi Triangulation.
With just two lines of code you can send data to the cloud in minutes, with no complex device registration or provisioning required. With a powerful JSON-based API, you can program the Notecard over USB, or control it from your preferred microcontroller or single-board computer using one of our open-source firmware libraries. Connect from your preferred host to the Notecard using Serial or I2C.
The Notecard is designed to work with a cloud service for ingesting and processing device data. Notehub provides secure device connectivity, project and fleet management, and simple routing to 3rd party cloud services.
The Notecard is meant to be used with a Notecarrier. The Notecard WiFi is compatible with all available Notecarriers. See the Notecarriers section for more details or get started with a Blues Starter Kit.
