The SparkFun NEO-M8U GPS Breakout is a highly configurable GPS board made to exceptional standards. The NEO-M8U takes full advantage of Untethered Dead Reckoning (UDR) technology by u-blox. Providing constant navigational data without the need to electrically connect to a vehicle, the NEO-M8U reduces installation cost for  after-market dead reckoning applications.

The NEO-M8U module is a 72-channel u-blox M8 engine GNSS receiver, this means it has the capability to receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations within a ~2.5 meter accuracy. Supporting simultaneous reception of all three GNSS systems, combined with integrated 3D sensor measurements on the NEO-M8U, you will receive accurate, realt-time global positioning rates of up to 30Hz.

But why this GPS module? In comparison with others, this breakout maximizes positional accuracy in busy cities or covered areas. Despite sub-par signal conditions, constant positioning is provided in urban environments and is still available during complete signal loss (e.g short tunnels and multi-storey parking) . Using UDR technology, positioning begins as soon as power hits the board and before the initial GNSS fix. Lock time is reduced by way of the on-board rechargeable battery, the secondary power source will enable the GPS to get a lock in seconds!

Furthermore, the receiver supports I2C which means it is perfectly compatible with the qwiic system. Therefore no soldering is required to connect it to the rest of your qwiic system. However, there’s still 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 NEO-M8U: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library!

The SparkFun NEO-M8U GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M8U. This reduces the time-to-first fix from a cold start (~26s) to a hot start (~1.5s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.

 

Product Showcase: SparkFun Qwiic GPS Dead Reckoning Breakout

Note: This product requires an antenna, which is not provided as part of the product. Be sure to check out the antennas we have on store before hitting the checkout!

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.
