Proximity Tag

Reference Designs

With the advent of crowd-sourced GPS, proximity tags are increasing in popularity as an practical way to keep track of devices and things we own. The SmartTag reference design was developed to provide manufacturers a fast-track to their development thereby speeding time-to-market while reducing development effort and cost.

The SmartTag reference design offers all the required functionality including a LED and buzzer to provide visual and audible signal link-loss or find-me alerts, as well as a push button to silence the alarm. The design also supports SW over the air updates (OTA) to provide an easy way to upgrade devices that are in the field with the latest improvements. Furthermore, as the SmartTag reference hardware is built on Dialog’s best-in-class Bluetooth low energy device, the DA14580, it offers world-leading battery lifetime, a low Bill of Materials and enables miniature industrial designs of the proximity tags.
