1 Overview
1.1 Introduction
The RAK2245 is a complete and cost efficient LoRa gateway solution base on Semtech
SX1301 to help utilize the whole LoRa system developement. Developers can integrate
the Concentrator module into the main board to utilize the LoRa gateway funtion.
RAK2245 can support eight channels and available in multiple variants so it can be
used for internartinal standard bands. This ultra compact module measures just 60mm
x 30mm x14,9mm is believed to be the world’s smallest LoRaWAN gateway module
which includes a GPS module and a Heat Sink for better performance and thermal heat
dissipation management.
This has to be the best value and function for connectivity to address a variety of
applications; like Smart Grid, Intelligent Farm and other IoT enterprise applications.
Combined with a Stamp form factor, which enables easy integration into an application
board and also ideal for manufacturing of small series. Another feature is the
integration of Ublox GPS module which expands applications.
Note: There are 2 type version with RAK2245 Series for the various interface in
GPS mdoule.
If you need use the Cellular Module (RAK2013 series), you must select the
RAK2245 series I2C version. If you don't need the Cellular Module, any version
can be working well. The default version is UART.
