868MHz Lora/GPS_HAT Wireless Expansion Board Kit Compatible with Raspberry PI Built-in Temperature Sensors Low Battery Indicator Support DGPS SBAS SDK Commands

Features:
The transceivers uses long ranges modem to provide ultra-long ranges spread spectrum communication and high anti-interference, while minimizing current consumption.
With FSK, GFSK, MSK, GMSK, LoRa and OOK modulation, supports DGPS, SBAS(WAAS/EGNOS/MSAS/GAGAN).
GPS automatically switch between internal patch antenna and external active antenna, also support SDK command.
The board can automatically calculate and predict orbits using ephemeris data (up to 3 days) stored in internal flash memory, so the HAT can be quickly positioned with low power consumption even at indoor signal levels.
GPS support short circuit protections and antenna detection and built-in LNA for better sensitivity.
