1Overview
1.1 Introduction
LoRa tracker device RAK7200 is the best available prototyping LoRa sensor device
with built-in 3.7V rechargeable Li-ion battery and GPS modem. The RAK7200 is built-in
S76G which integrats the ultra low power ARM Cortex-M3 STM32L073 microcontroller
and SX1276 LoRa long range modem and onboard CXD5603GF GPS modem. It is a
feature-packed tracker device for featured applications development.
It can as a quick prototyping tool for Internet-of-Things and LoRaWAN Network
integration. It is perfect for IoT applications such as asset tracking, smart vehicle
management and location-based services. And we provide the open source code which
make users quickly develop own applications.
1.2 Main Features
The main features are listed below:
Supports sleep mode, low power consumption.
Built-in digital output motion sensor LIS3DH, which has dynamic user selectable
full scales of ±2g/±4g/±8g/±18g and it is capable of measuring accelerations with
output data rates from 1Hz to 5kHz.
Built-in nano pressure sensor LPS22HB which functions as a digital output
barometer.
Built-in a 9-axis sensor which include the triple-axis gyroscope and the triple-axis
accelerometer and the triple-axis magnetormeter.
Supports latest LoRaWAN 1.0.2 protocol stack and supports Activation by
Personalization (ABP) or Over the Air (OTA) working mode.
Onboard Antennas for LoRa modem and GPS.
Supports Micro USB or built-in battery for power supply.
Supports global license-free frequency band: EU433, CN470, EU868, US915,
AS923, AU915, KR920 and IN865.
