• Built-in ceramic patch antenna

• Built-in data logging

• Automatic antenna switching

The MTK3339 is a GPS System on Chip (SoC). This extremely small GPS module offers both high quality and high sensitivity. The module features a built-in patch antenna but you can also add an external 3V active antenna via the u.FL connector, if you wish. The MTK3339 also features built-in data logging for recording track, time and location.

It can track up to 22 satellites on 66 channels and has a sensitivity of -165 dBm. Alongside this, the MTK3339 offers low power operation at just 20mA during navigation operations.

In addition to the MTK3339 chipset, there is a 3.3V LDO regulator which enables you to power the module with 3.3-5 Vdc. There is an “ENABLE” pin to switch the module off using an MCU pin or switch, plus there is the option to add a CR1220 coin cell battery to keep the RTC running.

A Red LED is there to blink at 1Hz while searching for satellites, and to blink every 15 seconds when a fix is found, to conserve power.

GPS stands for Global Positioning System and is a navigation system that utilises satellites. GPS is able to provide information on locations, velocity and time. It is a popular navigational system used in cars, trucks, boats and aeroplanes.
