RAK2270 Sticker Tracker Datasheet

Overview

Description

RAK2270 Sticker Tracker is a battery-powered LoRaWAN tracker with a label-like form factor powered by STM32WLE5. It’s compact; simply tear, peel, and stick RAK2270 to any product to virtually track its location in real time by leveraging the location estimator functionality of the Helium network server. It is activated using a Ri sensor, making it buttonless for ease of use.

With its built-in temperature sensor, it measures temperatures ranging from -20° C to +60° C with a temperature resolution of 0.1° C while simultaneously uploading the data to the server. It also includes an integrated 3-axis accelerometer that automatically adjusts the device positioning frequency. Because it detects whether the device is stationary or moving, it reduces device usage time.

Data, such as time, temperature, and motion state, remains safe and stored in an EEPROM storage space with a storage capacity of up to 64KB. Data can be saved locally when out of coverage and retained when coverage is restored. RAK2270 supports various LoRaWAN bands, including IN865, EU868, AU915, US915, KR920, RU864, and AS923-1/2/3/4.

Specifications

Overview

Block Diagram

RAK2270 integrates one RAK3172-SiP, one LIS3DHTR, one LiMnO₂ battery, and one EEPROM.

The RAK3172-SiP provides the required LoRa modem and processing functions.
The LIS3DHTR is used to determine the frequency of data transmission based on motion state judgment.
EEPROM is used for local data storage.
The LiMnO₂ battery powers the system with a nominal capacity of 600 mAh.
