Product Details
GPS (Global Positioning System) - Adafruit
Adafruit 746 Ultimate GPS Breakout Board
The Adafruit 746 Ultimate GPS Module is a breakout board based on the MTK3339 GPS SoC. This add-on board enables you to add quality GPS functionality to your base board or breadboard. It is called the “Ultimate” GPS module as it provides you with great GPS functionality, plus lots of bonus extras.
This module is great for working with the MTK3339 chipset on applications such as; smartphones, vehicles, personal trackers, digital cameras and other industrial applications. Its high sensitivity makes it ideal for dense environments, such as busy cities.
• Fully assembled
• High quality
• High sensitivity: -165 dBm
• Built-in ceramic patch antenna
• Built-in data logging
• Automatic antenna switching
More about the MTK3339 …
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.
What else is on-board?
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.
What is GPS?
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.
