SparkFun GPS Breakout - XA1110 (Qwiic) Hookup Guide
The XA1110 GPS module from GTOP is a rare bird indeed. GPS modules are hard to come by, but an I2C GPS+GLONASS module? Now we’re cooking with peanut oil! This small module also utilizes the MediaTek MT3333 chipset, loaded with specialized SparkFun firmware that enables both I2C and Serial ports simultaneously. Using I2C means you won’t have to tie up your serial port with GPS, leaving it open to other possibilities.
This module is configured with an on-board RTC battery that enables a warm-start functionality. (Giving the XA1110 just five seconds to first fix) A U.FL connector gives you the option to hook up an external antenna via a U.FL cable
This hookup guide will show you how to get started figuring out where on Earth you are. You’ll also learn how to change the update rate of the GPS up to 10 Hz as well as change the baud rate.
To get started, you’ll need a microcontroller to, well, control everything.
Now to get into the Qwiic ecosystem, the key will be one of the following Qwiic shields to match your preference of microcontroller:
You will also need a Qwiic cable to connect the shield to your GPS module, choose a length that suits your needs.
If you aren’t familiar with the Qwiic system, we recommend reading here for an overview.
