Datasheet

The Dragino Lora/GPS HAT is an expansion module for LoRaWan and GPS uses

with the Raspberry Pi. This product is intended for those interested in developing

LoRaWAN solutions.

The Lora/GPS HAT is based on the SX1276/SX1278 transceiver. The add on L80

GPS (Base on MTK MT3339) is designed for applications that use a GPS connected

via the serial ports to the Raspberry Pi such as timing applications or general

applications that require GPS information.

The transceivers of the Lora/GPS HAT feature the LoRa™ long range modem that

provides ultra-long range spread spectrum communication and high interference

immunity whilst minimising current consumption. The Lora/GPD HAT can achieve a

sensitivity of over -148dBm using a low cost crystal and bill of materials. The high

sensitivity combined with the integrated +20 dBm power amplifier yields industry

leading link budget making it optimal for any application requiring range or

robustness. 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.

This board can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal flash memory, so the HAT can fix position quickly even at indoor signal levels with low power consumption. With AlwaysLocate™ technology, the Lora/GPS HAT 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.
