GNSS3 click

GNSS3 click carries SIMCom's SIM33ELA standalone GNSS module with an integrated antenna (and a connector for an external one). GNSS stands for Global Navigation Satellite System, an umbrella term that describes both the United States GPS and the Russian GLONASS global positioning systems. The SIM33ELA module has MTK's high sensitivity navigation engine. It features EPO orbit prediction, AGPS, SBAS ranging (WAAS, EGNOS, GAGAN, MSAS). GNSS3 click communicates with the target MCU through mikroBUS UART pins (RX, TX), with additional functionality provided through RST and INT pins. The board uses a 3.3V power supply.
