Description
The RAK2245 is a complete and cost-efficient LoRa® gateway solution based on Semtech SX1301 to help utilize the whole LoRa® development system. Developers can integrate the concentrator module into the main board to utilize the LoRa® gateway function.
RAK2245 can support eight channels and is available in multiple variants so it can be used for international standard bands. This ultra-compact module measures just 60mm x 30mm x 14.9mm is believed to be the world's smallest LoRaWAN® gateway module which includes a GPS module and a heatsink 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 farming, 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.
