Device-to-cloud Wi-Fi data pump module for IoT
The Notecard Wi-Fi provides bidirectional, secure communication from edge devices to the user’s cloud of choice using the 2.4 GHz band, a frequency that’s better for penetrating obstructions. With the availability of Notecard Wi-Fi, says the company, developers can now build and deploy applications that rely on Wi-Fi and global cellular connectivity with minimal hardware or firmware changes.
The company’s Notecard product line was launched in January of 2021 as a cellular-focused IoT solution. The Notecard is a 30 x 35-mm system on a module device-to-cloud data pump that provides the communication layer between edge devices and customer clouds over global cellular or Wi-Fi. The Notecard product line is designed for IoT workloads where low power consumption is key, commonly drawing 8 uA at rest and able to be configured to “wake up” key parts of the device based on intervals or device movement.
The Notecard embeds industry standard encryption technology to secure data at rest and in transit. Certificates and keys are baked into the Notecard at the time of manufacture, saving administrative effort during deployments. Coupled with the Blues Wireless Notehub, device builders can securely gather, and send device data to their cloud of choice without spending design cycles on connectivity.
Notecard Wi-Fi complements the Notecard line for those users who predominately deploy cellular-based devices and need a Wi-Fi solution for a portion of the deployment due to local conditions. Users may swap between Notecard Cellular, and Notecard Wi-Fi with minimal hardware, firmware, or Blues API changes. Notecard Wi-Fi also suits users who plan to deploy a cellular-based solution but prefer to build their initial proof-of-concept or prototype with Wi-Fi connectivity as a way of exploring Blues Wireless APIs and evaluating the product.
The company has also announced a beta program for Sparrow, a new product designed for deployments where several devices are located in proximity such as an office building, equipment yard, or hospital grounds. Sparrow allows devices to share a backhaul by enabling a LoRa network for devices to communicate. Backhaul is provided by a cellular network or Wi-Fi Notecard. Sparrow will be released and made generally available later in 2022. The company is accepting sign-ups from those interested in participating in the beta program.
The Wi-Fi notecard is available for purchase from as a standalone device, or as part of a Raspberry Pi starter kit or Feather-compatible developer kit for prototype acceleration.
