The Notecard is compatible with nearly every microcontroller (MCU) from an 8-bit Arduino to 32-bit ESP32 or STM32. 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. Connectivity is provided by AT&T and backed by roaming agreements AT&T has with top providers around the world. 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 AT&T and backed by roaming agreements with top providers in regions outside of the United States. For a full list, please see our documentation article on Notecard’s supported countries .
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 Notecard.
