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 LoRa 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.

This kit comes with 

  • 1 x RAK2245 Pi HAT
  • 1 x Raspberry Pi 3 Model B+
  • 1 x 16GB TF Card
  • 1 x Antenna for LoRa®
  • 1 x GPS antenna

RAK2245 Pi HAT & Raspberry Pi 3B+ & 16G TF Card

The RAK2245 Pi HAT is a complete and cost-efficient LoRa 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

The RAK2245 Pi HAT is designed to provide GPS data over the UART interface. This is the case it is connected to another board (such as the RAK2013) that utilizes the UART interface, there will be limitations as far as GPS data goes.

However, in order to support LoRaWAN gateways with cellular connectivity on the Raspberry Pi, RAKwireless also designed a product which utilized a modified concentrator (RAK2243 Pi HAT) that uses the i2C bus to send GPS data.

Due to resource limitation at this stage, RAK2245 Pi HAT I2C edition (RAK2243) is not offered commercially. It is only used for the purpose of the RAK7243C gateway. 

RAK2245 Pi HAT

The standalone RAK2245 Pi HAT doesn't allow for the extension of its connectivity option with cellular. If for the purpose of your project you require a LoRaWAN gateway with cellular backhaul, we recommend you purchase the RAK7243C in case of the Raspberry P platform. Should you need an industrial class gateway with cellular connectivity, there is the Rak7249. 

In case using the I2C for your GPS data stream is a must as you require the UART for another data stream, you can use the following modification manual. Note however that this is a hardware modification and is not reversible. RAKwireless is not responsible for any damage you might cause the product.

RAK2245 Pi HAT

All RAK2245 configurations support 8 channels (for a number of global bands). With its ultra-compact design, it is believed to be the world's smallest loRaWAN gateway module including GPS and heatsink. It is based on a Semtech SX1301 transceiver, complemented by dual SX125x RF front end I/Q transceivers. In a manner of speaking, it follows the design of the RAK831, the same great performance with a smaller form factor and with improved cooling and boosted max output features.
