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.

Main Features

RAK2245 96Boards has the same compact form factor and great performance as the other RAK2245 modules. It is fully compatible with modules supporting the 96Boards standard, such as Nitrogen and Orange Pi. Thus it is an easy way to integrate LoRaWAN into an already existing solution utilizing a 96Boards compatible IoT module.

As with the other modules in the RAK2245 line, it is based on the Semtech 1301 and dual SX1257/58 front-end chips. It is a full-fledged 8 channel LoRa Concentrator with a number of improvements over the last generation (RAK831)..
