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.
Different models of the Blues Wireless Notecard are available that connect to LTE-M, NB-IoT, and Cat-1 networks globally. When LTE-M, NB-IoT, or Cat-1 aren’t available, the Notecard is also supported by UMTS/HSPA+ and GSM/GPRS/EDGE wireless standards.
Global coverage is available in 135 countries, with direct support provided by leading providers and carriers. For a full list, please see our documentation article on Notecard’s supported countries.
A system on module (SoM) is a circuit board that integrates a system function on a single module/device. Unlike a single board computer like the Raspberry Pi or a microcontroller, a SoM generally serves a single special function.
The Blues Wireless Notecard is a cellular SoM. The Notecard is a secure device-to-cloud data-pump that comes with 500MB of data and 5,000 monthly consumption credits. The Notecard itself is a tiny 30mm x 35mm SoM and ships ready to embed in a project via its m.2 connector. To make prototyping IoT solutions even easier, Blues Wireless also provides a series of expansion boards to host the Notecard called Notecarriers.
The Blues Wireless Notecard, combined with the Notecarrier-AF, is the easiest way to add cellular connectivity to your MCU-based IoT project. Blues Wireless provides a Feather Starter Kit that includes a Adafruit ESP32 HUZZAH to get you started as quickly as possible. Alternatively, if you are invested in the Raspberry Pi platform, you can get started with the Raspberry Pi Starter Kit.
A cellular IoT module is a system on module (SoM) that integrates a system function (e.g. cellular) on a single module or device. Unlike a single board computer or a microcontroller, a SoM generally serves a single unique 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).
There’s two main reasons the Notecard may be having issues connecting to a computer via USB.
