DFRduino GPS Shield for Arduino uses ublox LEA-5H.
The LEA-5H is a high performance stand-alone GPS and GALILEO receiver module designed to allow easy, straightforward migration from its LEA-4 predecessors. It features u-blox' KickStart weak signal acquisition technology, as well as flexible connectivity options. The LEA-5H comes with built-in Flash memory that enables firmware updates and the storage of specific configuration settings in a non-volatile RAM. The built-in antenna supervisor supports external and active antennas, such as u-blox' ANN high performance GPS antenna.
u-blox KickStart provides accelerated startup at weak signals, and DFRobot's featured SuperSense® Indoor GPS is capable of tracking and acquiring even extremely weak signals. This makes the LEA-5H suitable for solutions using small or covert antennas.
Suggestion: Customers can buy TEL0042 Built-in GPS Antenna to equip this GPS shield and maximize its power.

- How GPS Receivers work
GPS is accurate and handy to use, so much so that we rely on it more and more every day. It's not often we take the time to learn how it works. The idea of GPS refers to a Global Positioning System; a collection of satellites in orbit above the Earth...

- Potentiometers and the Arduino Uno
Variable resistors come in all shapes and sizes, and they all do the same basic job. They allow you precisely control voltage/current flow within a circuit. The most common type of variable resistor we see in DIY electronics is the Potentiometer, or ...
- Cosplay Blaster
Hey guys! First time poster. I've been working on a blaster for my girlfriend's costume, and I thought I would share it with everyone. When triggered, it plays a selected sound effect and flashes the light. Pretty simple :)
- Coffee Grinder With Arduino
Using a few bits and pieces, this ordinary coffee grinder now has two presets to run the motor for a programmable length of time. The idea being that the grinder running for a set amount of time will deliver a certain amount of coffee each button press meaning the beans can be stored unground, keeping them fresher for longer. I completed this project for a friend, Ian, who lives for coffee. Ian wanted the same functionality in h...
- The Hipster Coaster
We wanted to make a interactive display of the fun that can be had with DIY projects to take to Sydney Mini Maker Faire. We decided to do so by utilising the TinkerKit Braccio from Arduino.org, alongside some 3D Printing ingenuity, for an engaging display for all ages. Enter the Hipster Coaster in all its glory. All the parts were printed seperately on our family of Lulzbot 3D Printers, later stuck together using a mi...
