RAK815 WisTrio LPWAN Tracker Datasheet

Overview

Description

RAK815 WisTrio LPWAN Tracker is a wireless remote solution based on the RAK813 + GPS + MEMS + HT+LCD design. It integrates the latest LoRaWAN 1.0.2 protocol and Bluetooth 5.0, supporting the LoRaWAN working mode and Bluetooth transparent transmission up to 300 meters.

RAK815 (RAK813 BreakBoard) has a built-in GPS, acceleration, temperature, and humidity sensors expanded I2C LCD interface. A case applications are provided that can configure LoRaWAN parameters using Bluetooth, display sensor data using LCD, and upload sensor data to the LoRaWAN network. The board is equipped with three customizable buttons and two customizable LEDs, allowing users to implement their ideas with open-source code available on our Github Repository.

The board also supports battery-powered products, which greatly expand the product application scenarios. It is designed with a function to enter the low-power mode when the device is detected to be stationary to ensure battery life. The device also supports RAK831 + Ri3 gateway to use. You can graphically display the various data of the sensor in the Cayenne platform and can also support the real-time observation of sensor data on the phone.

Overall, this LoRa device has various functionalities designed in a single board that could help you develop your own LoRa projects.
