Featuring an improved STM32 MCU, an onboard dual SIM capability, and an improved Low IQ power supply, Notecard Cellular (Narrowband) is a drop-in functional replacement for the original “Green” Notecard at a lower price.
Notecard is a device-to-cloud data pump that reduces the complexity of building connected solutions with secure, reliable cellular. As an embeddable system on module (SoM), Notecard can be used with any microcontroller for both greenfield and retrofit projects using your own design, or one of our custom designed Notecarriers.
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 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 Notecard using Serial or I2C.
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 third-party cloud services.
Notecard is meant to be used with a Notecarrier. Notecard Cellular (Narrowband) is compatible with all available Notecarriers. See the Notecarriers section for more details or get started with a Blues Starter Kit.
Ordering Note: Notecards purchased from the Blues Shop will ship with a Developer Firmware Release version pre-installed. If you require a Long-Term Support (LTS) version for a Shop order, please contact Sales for assistance.
