SparkFun GPS Breakout - ZOE-M8Q (Qwiic)

The SparkFun ZOE-M8Q GPS Breakout is a high accuracy, miniaturized, GPS board that is perfect for applications that don't possess a lot of space. The on-board ZOE-M8Q is a 72-channel GNSS receiver, meaning it can receive signals from the GPS, GLONASS, BeiDou, and Galileo constellations. This increases precision and decreases lock time and thanks to the onboard rechargable battery you'll have backup power enabling the GPS to get a hot lock within seconds! Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

U-blox based GPS products are configurable using the popular, but dense, windows program called u-center. Plenty of different functions can be configured on the ZOE-M8Q: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library. We've also made sure to configure the UART pin grouping on the breakout to an industry standard to insure that it easily connects to a Serial Basic.

The SparkFun SAM-M8Q GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZOE-M8Q. This reduces the time-to-first fix from a cold start (~30s) to a hot start (~1s). The battery will maintain RTC and GNSS orbit data without being connected to power for up to five hours. Since the ZOE-M8Q is a tiny GPS receiver and to minimize its footprint, we've added a U.FL connector to allow the use of both large standard ceramic antennas as well as very small chip scale antennas.


The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

GPS Basics

December 14, 2012

The Global Positioning System (GPS) is an engineering marvel that we all have access to for a relatively low cost and no subscription fee. With the correct hardware and minimal effort, you can determine your position and time almost anywhere on the globe.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

1 Electrical Prototyping

Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

tinyest GPS module ever

This is a unbelievably tiny GPS / GNSS module. It works like a charm with either passive or active antennas. Make sure you also buy an antenna and matching u.fl adapter. I have used Sparkfuns matching Arduino library and it's really easy to integrate using Qwicc/I2C.
