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 WisNode LoRa
• 1 x Gluestick Monopole
• 1 x micro-usb cable
• 1 x Raspberry Pi 3 Model B+
• 1 x 16GB TF Card
• 1 x LoRa antenna
• 1 x GPS antenna

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. 

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.

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.

If the items are visibly damaged on receipt it's best to sign the carrier's delivery note accordingly if possible. Damaged items should be returned in their original packaging complete with all accessories and documentation. Once received back into our warehouse we'll issue a replacement or full refund via your original payment method. If return shipment is necessary we will of course cover this cost.

Items faulty on arrival

If your items are faulty on arrival, you have 30 calendar days in which to inform us of the fault. Items should be returned in their original packaging complete with all accessories and documentation. Once we have verified the fault, we'll issue a replacement or full refund to you via your original payment method. We will also cover the cost of shipping the item back to us.

Incorrect or missing items

Whilst we do our very best to make sure your order is correctly fulfilled in our warehouse our staff are only human and so on the odd occasion mistakes do happen. If you receive the incorrect items or are missing an item from your order please inform us within 7 working days of receipt so we can work with you to rectify the situation. For missing items we will ship the missing products out to you immediately, and in the case of incorrect items we will typically ask you to ship the items back to us (at our expense) and send the correct items out to you by return.

Unexpected delivery

If you received an order from us which you were not expecting, we would be obviously very grateful if you could return it to us so we can re-route it to its rightful home! The best way to do this is to take it to your local post office and send it to the returns address listed below.

ABOUT PI SUPPLY

The business was founded in 2008 as a hobby car audio business under the name Raamaudio UK Ltd. In 2012, founder Aaron Shaw got his first Raspberry Pi and the company changed direction. Pi Supply is a creator of innovative accessories for the Raspberry Pi mini-computer and a retailer of other maker products from around the globe.

Our aim is to provide high-quality electronic products to the global Raspberry Pi and Maker communities, through a fast distribution service that is expanding daily.

We've grown from a one-man band operation working in a dusty warehouse in Kent with two silly dogs to a growing team based all over the UK and EU.

HOW Pi SUPPLY STARTED

Our Founder hated having to reach under his bed to turn his Raspberry Pi on and off. So he decided to do something about it. Introducing….the Pi Supply Switch! The very first creation that started this company!

Since then, we've gone on to successfully fund a number of our own other Raspberry Pi products through Kickstarter, and stock over 800 items in our store. You can view our Kickstarter campaigns here:

• Pi PoE Switch HAT - Power over Ethernet for Raspberry Pi
• PaPiRus - the ePaper Screen HAT for your Raspberry Pi
• Gert VGA 666 Kit - Hardware VGA for Raspberry Pi
• Bright Pi - Bright White & IR Camera Light for Raspberry Pi
• Fish Dish - A Raspberry PiAdd-Onn Board
• Pi Supply - Intelligent Power Switch for Raspberry Pi
• PiJuice - A Portable Project Platform For Every Raspberry Pi

We have always centered around the core principle of supplying educational and hobby electronics to a wide variety of customers involved in the Maker Movement. Our products make it easier for beginners to get started with electronics, coding, and general computing.

We manufacture a range of our own Raspberry Pi add-on kits and HATs from high-end audio streaming boards called JustBoom to ePaper HATs that are sold through our Maker Shop and resellers all over the world.
