Featuring an improved STM32 MCU, an onboard dual SIM capability, and an improved Low IQ power supply, Notecard Cellular is a drop-in functional replacement for 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 3rd 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.

Notecard is a device-to-cloud data pump that reduces the complexity of building connected solutions with secure, reliable cellular and WiFi. 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. Notecard Cell+WiFi (Narrowband) allows for dynamic fallback from WiFi to cellular and indoor location tracking via WiFi Triangulation. |

Notecarriers are companion development boards designed to make it easy to prototype and deploy IoT solutions with Notecard.
Notecarrier B is a small form-factor Notecarrier, only slightly larger than Notecard itself. Unlike other Notecarriers, Notecarrier B does not include an external SIM slot.
Included is a flexible Molex 209142 antenna for use with either LTE or GPS. If you require a dual LTE/GPS antenna, we recommend adding on the flexible LTE+GPS antenna (or you may choose to use your own preferred antenna).
Notecarriers require a Notecard to function. Notecarrier B is compatible with all available Notecards. See the Notecards section for more details or get started with a Blues Starter Kit.
Available Variations

Add Notecard to Arduino MKR and PRO boards with this slim Notecarrier!
Notecarriers are companion development boards designed to make it easy to prototype and deploy IoT solutions with Notecard.
Notecarrier R is a small form-factor Notecarrier, only slightly larger than Notecard itself. Unlike other Notecarriers, Notecarrier R does not include an external SIM slot. It’s similar to Notecarrier B, but instead of a Qwiic connector, it has an ESLOV connector common to many Arduino MKR and PRO Portena boards. ESLOV provides I2C pins, as well as an additional GPIO, which we’ve connected to Notecard’s ATTN pin.
Included is a flexible Molex 209142 antenna for use with either LTE or GPS. If you require a dual LTE/GPS antenna, we recommend adding on the flexible LTE+GPS antenna (or you may choose to use your own preferred antenna).
