NORA-B1 series (open CPU)
Stand-alone Bluetooth 5.2 low energy modules
The XPLR-IOT-1 explorer kit provides a complete platform for developing various proof-of-concept IoT applications. The kit includes everything needed for an out-of-the-box experience. Its embedded SIM with u-blox MQTT Anywhere and MQTT Now trial accounts enable connection to the Thingstream IoT service delivery platform. With only a few initial manual steps, the kit can publish data to the cloud and demonstrate a complete end-to-end solution.
The device supports Wi-Fi, Bluetooth, and LTE-M/NB-IoT cellular communication. A dedicated low-power GNSS receiver provides accurate positioning data. It has integrated sensors for temperature, humidity, pressure, ambient light, magnetometer, gyroscope, accelerometer, and battery gauge.
With the embedded SIM, the device is pre-configured for cellular networks in many countries across the globe. Alternatively, the user can leverage the available nano SIM slot to connect with a network operator of choice. When connecting with the u-blox MQTT Anywhere service, the XPLR-IOT-1 kit uses the MQTT-SN protocol for power and data-efficient communication to the Thingstream platform. If Wi-Fi is preferred, the built-in Wi-Fi module and the u-blox MQTT Now service offers an alternate route to the cloud.
The XPLR-IOT-1 kit comes with pre-flashed application software, also available as source code. It collects sensor and positioning data from the device for publication to the Thingstream platform, where the Data Flow Manager receives and processes the data. The available Node-RED programming example shows a quick and easy dashboard visualization of the data.
The device is controlled with the Nordic Semiconductor nRF5340 wireless System-on-Chip (SoC) in the NORA-B1 wireless MCU module. It features a dual-core Arm Cortex-M33 MCU with up to 128/64 MHz clock frequency and 512 + 64 kB RAM memory and 1024 + 256 kB flash. The SoC can host custom applications developed with the Nordic nRF Connect SDK or the Zephyr development environment.
