1 Overview
1.1 Introduction
RAK2287 is a LoRa concentrator card with mini-PCIe form factor based on SX1302,
which enables an easy integration into an existing router or other network equipment
with LoRa Gateway capabilities. It can be used in any embedded platform offering a
free mini-PCIe slot with SPI or USB connection. Furthermore, ZOE-M8Q GPS chip is
integrated on board.
RAK2287 is a complete and cost efficient LoRa gateway solution offering up to 10
programmable parallel demodulation paths which are 8xSF5-SF12 LoRa demodulators,
8xSF5-SF10 LoRa demodulators, 500 kHz LoRa demodulator and (G)FSK
demodulator. It can detect at any time, any packet in a combination of 8 different
spreading factors(SF5 to SF12) and 10 channels, and demodulate up to 16 packets at
any time. It targets smart metering fixed networks and Internet-of-Things (IoT)
applications, covering up to 500 nodes per square kilometer in an environment with
moderate interference. Another feature is the integration of Ublox GPS module which
expands applications.
