GPS 4 Click Board
The GPS 4 Click Board carries the L70 compact GPS module from Quectel. The click is designed to run on either 3.3V or 5V power supply.
It communicates with the target microcontroller over UART interface, with additional functionality provided by the following pins on the MikroBUSline: PWM, AN, RST.
The GPS 4 Click Board is based on the L70 compact GPS module from Quectel. The click is designed to run on either 3.3V or 5V power supply.

L70, an SMD type module, brings the high performance of MTK positioning engine to the industrial applications with a compact profile, ultra low power consumption and fast positioning capability.
Combining advanced AGPS called EASY(Embedded Assist System) and proven AlwaysLocatetechnology, L70 achieves the highest performance and fully meets the industrial standard. EASYtechnology ensures L70 can calculate and predict orbits automatically using the ephemeris data (up to 3 days) stored in internal RAM memory, so L70 can fix position quickly even at indoor signal levels with low power consumption.
With AlwaysLocatetechnology, L70 can adaptively adjust the on/off time to achieve a balance between positioning accuracy and power consumption according to the environmental and motion conditions.
How it Works
A constellation of satellites sends a continuous signal towards Earth. On-board every satellite is an atomic clock, and all of them are synchronised, thanks to a reference time scale defined by the whole system. So, that the signals coming from the different satellites of the same constellation share the same reference time scale.
The user wanting to use GPS to determine its position must have an antenna that receives the signals coming from the satellites, and a receiver that translates these signals. The antenna position will be deduced from the measurements of the time delay between the emission time (satellite) and the reception time (receiver) for at least 4 signals coming from different satellites.
