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.
