Product User’s Manual – 915MHz 8-channel LoRa Gateway Hat for Raspberry Pi

1.0 INTRODUCTION

Lately LoRaWAN has been increasingly famous in the area of Internet of Things (IoT)

applications. Many applications in our daily lives require remote control or monitoring, but at

the same time high power consumption or data streaming is not necessary. This is where

LoRaWAN came in and take its role due to its feature - low power, low payload. In

LoRaWAN, LoRa Gateway has become one of the most important components because it

receives signals from LoRa end devices/nodes and upload them to cloud server via Internet.

915MHz 8-channel LoRa Gateway HAT (HAT-LRGW-915) is the HAT specially

designed to be used with Raspberry Pi board for LoRaWAN application. Used together with

Raspberry Pi board, this whole thing can instantly become a LoRa Gateway with proper

software setup. What is more important, the price is affordable compared to industrial-grade

LoRa Gateway, suitable for education, makers, hobbyist, or individuals.

This HAT is integrated with 900MHz ~ 930MHz LoRa gateway concentrator module

manufactured from RisingHF, able to receive LoRa signals within frequency range from

900MHz to 930MHz (center frequency 915MHz). Not only that, this module is capable of

receiving signals from LoRa end devices/nodes up to 8 different channels(frequencies) with

different spreading factor simultaneously at one time! It also comes with SMA antenna

connector, in which users can mount it with their favourite or customised antenna. This HAT

also has built-in USB debug port, where users can use it for Raspberry Pi monitoring and

debugging, or even use the whole gateway just like any other standard Raspberry Pi!

Apart from Raspberry Pi board pin header, the HAT provides pin breakout. With

manual wiring, user can possibly connect it with their favourite platforms such as Arduino,

etc, possibilities is limitless.

* This HAT does not contain LoRaWAN, the controller Raspberry Pi/other platform will need

to have LoRaWAN stack, which can be done through software setup. (The steps for

Raspberry Pi setup are available from Cytron Wiki or Tutorial page)

Features:

● Easy integration with Raspberry Pi or possibly other platform to become a LoRa

gateway

● Multi channels with multi spreading factor, able to receive LoRa signals from LoRa

end devices/nodes up to 8 different channels with different spreading factor

simultaneously at one time

● Supports frequency range 900MHz ~ 930MHz

● Comes with SMA antenna connector, in which user can mount it with their favourite

or customised antenna (900-930MHz)

● Pin Breakout from onboard gateway/concentrator module itself for integration of this

hat with other platform

● USB debug port ready for debugging purpose (used with Raspberry Pi board only)

● Interface via SPI with Raspberry Pi

● Suitable for low power wireless sensor network applications such as irrigation

systems, smart metering, smart cities, smartphone detection, building automation, etc.
