Overview

Avnet Silica, official partner of ARM Technology, developed an ARM® mbed Enabled™ Sensor Node board delivering the low power operation and secure connectivity required for Internet of Things (IoT), smart sensing and cloud applications.

Avnet Silica has combined best-in-class processing, sensing, security and connectivity from STMicroelectronics with the ARM® mbed™ IoT Device Platform, which provides a complete solution including an advanced OS to run hardware, device management in the cloud and advanced security.

Powered by ST’s ultra-low-power STM32L4 microcontroller, the Sensor Node board enables quick development of smartsensor applications that can make use of several connectivity options. Choices include Bluetooth LE connectivity, which enables an easy connection with smartphones, and sub-GHz 6LoWPAN connectivity for long-range communications. Key hardware on the board includes the highly integrated ST SensorTile module, which integrates the ultra-low-power STM32L4 ARM® Cortex®-M4 microcontroller, plus ST’s very low-power BlueNRG-MS Bluetooth low energy (BLE) single mode network processor and ST TESEO III GNSS receiver, together with a wide selection of ST’s sensing devices like accelerometer, gyroscope, magnetometer, barometer and microphone plus STSAFE-A100, a highly secure solution which acts as a secure element providing authentication and data management services to the local host.

The Sensor Node board also offers some additional onboard sensors from ST that provide support for humidity, temperature, proximity and ambient light.

In addition to ARM mbed OS 5, the board also supports STM32Cube middleware and is further supported by software demos and libraries provided for both mbed OS and STM32Cube.
