Product Description: RAK2245 Pi HAT is a module with Raspberry PI form factor. It can be plugged into Raspberry PI such as Raspberry Pi 3 Model B+ as a complete RF front end of LoRaWAN gateway.It supports eight channels and is available for LoRaWAN global frequency bands. The board is the smallest LoRaWAN gateway concentrator which integrates the Ublox MAX-7Q GPS Module and heat sink. The board can provide low data rate LoRa radio links in ultra-fast speed. It is powered by a Semtech SX1301 transceiver concentrator that is capable of managing packets from many remotely dispersed end-points. Two Semtech SX125X are integrated for RF front end I/Q transceivers. The RAK2245 Pi HAT is a complete and cost efficient LoRaWAN gateway solution that can help you develop a full LoRa system. This is an economical way to create different solutions like smart grid, intelligent farm and other IoT applications. It is also ideal for manufacturing small series that can expand into more applications.
