Connect to the World with Ease
Build the next generation of data-driven intelligent products with the Notecard WiFi.
We packaged Wi-Fi connectivity, low-power design, industry-leading security, and cloud communications into a single affordable 30mm x 35mm System-on-Module [SoM].
The Notecard WiFi thrives in line-powered device clusters with a high sampling rate, fixed same-room scenarios, cell signal-challenged locations, and beyond.
Simplified Development

Frequently Asked Questions
Yes. The Wi-Fi Notecard uses the same m.2 Key E connector as the Cellular Notecard and as such, can be used in any one of our Notecarriers or a custom, Notecard-based design.
The Notecard is compatible with any microcontroller (MCU) from an 8-bit Arduino to 32-bit ESP32 or STM32 and every major Single Board Computer (SBC) platform. Some popular examples include the Adafruit Huzzah32, STM32 Nucleo, Arduino Nano, ESP32-WROOM, among many others. The Notecard communicates over either I2C or UART, so it acts as a peripheral that you can connect to a product’s existing I2C bus or UART connection.
It’s also possible to communicate with the Notecard from any embedded language, including compiled languages like C and C++, to interpreted languages like Python and JavaScript.
The Low-Power Wi-Fi transceiver used on the Notecard supports 2.4GHz Wi-Fi Networks.
No! The Blues Notecard is a small 30mm x 35mm system on module (SoM) that is able to be embedded in any IoT project on its own via its M.2 edge connector.
However, Blues offers a variety of Notecarrier host boards for easily adding cellular connectivity to a new or existing IoT solution for prototyping purposes. For cellular versions of the Notecard, Notecarriers also provide antennae for both the GPS and cellular modules. The cellular antenna on Notecarriers is also compatible with Wi-Fi Notecards.
Notecard: SoM peripheral with a cellular modem, IMU sensor, GPS modem, with an M.2 edge connector.
Notecarrier: A prototyping board with cellular/Wi-Fi and GPS antennae, used to breakout the pins on the Notecard’s M.2 connector.
Notehub: A cloud service, used as a backend to connect with the Notecard. Notehub.io securely receives all data and communications created by the Notecard. In turn, Notehub.io can securely sync encrypted data with the cloud application of your choice using VPN tunnels which eliminates the need for traffic to traverse the public Internet.
