LoRa/GPS Shield For Arduino
SKU 113990296
The LoRa/GPS Shield is an expension board for LoRa™/GPS for using with the Arduino.This
product is intended for those interested in developing LoRa™/GPS solutions.The LoRa/GPS
Shield is composed of LoRa/GPS Shield mother board and LoRa BEE.
In the LoRa part,the LoRa/GPS Shield is based on the SX1276/SX1278 transceiver.The
transceivers of the LoRa/GPS Shield feature the LoRa™ long range modem that provides ultra‐
long range spread spectrum communication and high interference immunity whilst minimising
current consumption. LoRa™ also provides significant advantages in both blocking and
selectivity over conventional modulation techniques, solving the traditional design compromise
between range,interference immunity and energy consumption.
In the GPS part,the add on L80 GPS (base on MTK MT3339) is designed for applications that use
a GPS connected via the serial ports to the arduino such as timing applications or general
applications that require GPS information.This GPS module can calculate and predict orbits
automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so the
shield can fix position quickly even at indoor signal levels with low power consumption. With
AlwaysLocate™ technology, the LoRa/GPS Shield can adaptively adjust the on/off time to
achieve balance between positioning accuracy and power consumption according to the
environmental and motion conditions.The GPS also supports automatic antenna switching
function. It can achieve the switching between internal patch antenna and external active
antenna.Moreover, it keeps positioning during the switching process.
