1 General

1.1. Introduction

M-GW1302S is Mini PCI-e board based on SX1302, with SPI interface, internal

PA and LNA, half-duplex design, for customer to develop LoRa gateway quickly.

SX1302 is the newest LoRa gateway chip that Semtech released, with SX1250 as

RF front-end chip, supporting SF5-SF12, compared with SX1301, SX1302 has higher

data communication speed rate and lower power consumption, simpler design and

higher performance.
