Low power asset tag from onsemi

onsemi has unveiled the RSL10 Asset Tag which comes with a battery life of up to five years.

Until now, the accepted battery life for asset tracking tags or beacons has been a year or even months. Described as a game-changer by onsemi, this much improved battery life has been achieved by the low power consumption of the RSL10 Bluetooth 5 radio SoC and additional enhancements at the firmware level.

Alongside the RSL10, the platform features a 3-axis accelerometer and environmental sensors (motion, pressure and temperature) to provide valuable data and insights into an asset’s environment, condition and orientation.

Each sensor is powered through a dedicated MOSFET load switch, controlled by the RSL10, which enables the overall system power consumption to be controlled on a per-sensor basis, which decreases the total power used.

Additional features of the platform include a low-cost antenna, matching circuit optimised for Bluetooth Low Energy transmissions, a multi-purpose dome switch and a 10-pin debugger that can be removed depending on the needs of the application.

The RSL10 Asset Tag is available with a comprehensive suite of development tools that include multi-protocol wireless support for Bluetooth Low-Energy connectivity and the Quuppa Intelligent Locating System Real Time Localization Services (RTLS).

Within the CMSIS-Pack, included with the evaluation board, onsemi has developed a custom application that demonstrates the ultra-low-power features and capabilities of the platform in an asset tracking use-case.
