Solution Components

Sync data with any cloud application

Native integration with AWS IoT Analytics, Azure, Datacake, Google Cloud Platform, Snowflake, Initial State, ThingSpeak, Ubidots, and your custom (public or private) cloud applications.
Notecard events are JSON and our system will filter and optimize them to your specifications using our routing templates and transformation.

Secure communications by default

From device-to-cloud, your data is secure with Notecard and Devices are authenticated with secure element keys, and data flows through TLS using encrypted “off the internet” communications and VPN tunnels.

Cloud-based firmware updates

Eliminate the hassle of remote DFU. allows for both cloud-based MCU host and Notecard firmware updates. Update a single device or an entire fleet with the click of a button.

Built-in data transformation layer

  • Reduce infrastructure and deployment complexity by transforming data before it gets to your cloud
  • Contains pre-defined transformations for common structures
  • Custom transformations through simple JSON expressions with JSONata

JSON based API. Insane power in a concise package.

  • Control Notecard with simple JSON commands
  • Data sent in JSON, securely and reliably to your preferred cloud
  • Bi-directional data flow. Control Notecard and host devices from your cloud

How to Evaluate Blues Wireless in 30 Minutes or Less

With Blues Wireless, you'll never worry about monthly or consumption fees.
Each billing account is refreshed to 5,000 credits each month with the ability to purchase more.


You can pick a starter kit based on ESP32, Raspberry Pi, or our own feather-compatible microcontroller Swan.


Plug the Notecard into the provided Notecarrier, then connect to your existing hardware.


Follow along with our quickstart. In 30 minutes, you'll have a device connected to the global cellular data network, and data flowing from device to cloud, and back to device again.


  • Feather kit and Swan kit contain MCUs. If you want our Raspberry Pi kit, you'll need your own Pi.
  • Swan lets you write code in C/C++, Arduino, and CircuitPython. It's also a powerful MCU and ready to run on edge-based machine learning like Edge Impulse. We have a guide for that.
