Frequently Asked Questions

    Does the Wi-Fi Notecard Work With Any Notecarrier?

    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.

    Which microcontrollers does the Blues Wireless Notecard support?

    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.

    What frequency range does the Wi-Fi Notecard support?

    The Low-Power Wi-Fi transceiver used on the Notecard supports 2.4GHz Wi-Fi Networks.

    Does the Blues Wireless Notecard require a Notecarrier to function?

    No! The Blues Wireless 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 Wireless provides a variety of Notecarrier host boards for easily adding cellular connectivity to a new or existing IoT solution for prototyping purposes. The Notecarrier also provides antennae for both the GPS and cellular capabilities of the Cellular Notecard (and the cellular antenna is also compatible with the Wi-Fi Notecard).

    What are the differences between the Blues Wireless Notecard, Notecarrier, and
    • 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. securely receives all data and communications created by the Notecard. In turn, 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.
