RoKiX Sensor Node
New Board

The sensor node integrates multiple sensors from Kionix and ROHM. These sensors enable the measurement of 3D-acceleration, 3D-magnetism, 3D-rotation, atmospheric pressure, and temperature by default sensors. Expansion connectors enable the addition of more sensors such as an optical heart rate sensor, ambient light sensor, RGB color sensor, magnetic hall effect sensor, etc.

This makes it an excellent choice for prototyping and developing Consumer IoT (Internet of Things) applications ranging from wearables, health and wellness, games and toys, and smart home devices to Industrial IoT applications such as smart city sensor networks, asset management and logistics monitoring, factory automation, etc.

A key feature of RoKiX Sensor Node is its focus on power, both in terms of flexibility and low power consumption. It can be powered by a rechargeable Li-Polymer battery, replaceable coin cell batteries, or via Micro USB. The automated power consumption system of the Bluetooth 5 SoC, and the configurable power management modes of the sensors, make the RoKiX Sensor Node a long-running, low power consuming system with a small footprint. The active time is about 8 hours of typical usage, and an estimated standby time of 200 hours.

The RoKiX Sensor Node comes in a compact (42x67x22mm) housing and has a programmable RGY LED, expansion capability with extended I/O connectors, and 64Mb of flash memory.

The sensor node comes with a mounting accessory so one can attach it to surfaces with screws or connect a watch band for wearing it on one’s wrist.

Software packages supporting the RoKiX Sensor Node include a Windows GUI with visualization and datalogging capability, a Python-based Command Line Interface (CLI), and an Android Data Logger App. The sensor node can be used with the Arm Mbed design tool, as well as Nordic Semiconductor’s nRF5 SDK, that enables secure over-the-air device firmware updates (OTA-DFU).
