Arduino compatibility provides ultimate flexibility

The Avnet NB-IoT Sensor Shield is a Cat M1 and NB-IoT board providing Arduino pinout connectors. The Arduino compatibility provides ultimate flexibility, leveraging on a huge ecosystem of compatible boards. It enables you to choose the microcontroller board that best fits your application, like STM32 Nucleo Boards, and combine them with sensors and other peripheral boards as needed.

The NB-IoT Sensor Shield is equipped with Pmod connectors for an extended compatibility with addional boards. The shield is based on Quectel BG96, a low power module supporting Cat M1, Cat NB1 and EGPRS fallback. GNSS is also supported. With AT commands Avnet NB-IoT Sensor Shield is easy to program and supports mbed OS for quick development and leveraging on free stacks like SSL, MQTT, COAP etc.

Ready for mbed OS5-A platform OS for IoT devices

  • ARMR mbed™ is a free, open-source embedded operating system designed specifically for the “things” in the Internet of Things.
    • Enables application and component libraries to work unchanged across MCUs, hence provides portability for developers and helps to deliver network effects for contributors
  • Consistent boot and C/C++ runtime across MCUs, including support across different toolchains, std library integrations
  • RTOS kernel
    • Built on the established, widely used, open source CMSIS-RTOS RTX
    • Very small kernel optimised for constrained memory devices
  • Common Driver APIs for all common peripherals, supported across all MCUs
  • Enhanced connectivity and security stack
