A GPS (Global Positioning System) and GNSS (Global Navigation Satellite System) breakout is a type of breakout board that allows a microcontroller or other electronic system to easily receive and interpret satellite signals for location and timing purposes. The board typically features a small circuit board with a set of pins that can be easily connected to a microcontroller or other device. The board also includes a GPS or GNSS module that receives signals from multiple satellites and calculates the precise location, speed, and time of the connected device. GPS and GNSS breakouts are commonly used in a wide range of applications, including navigation systems, drones, and other location-based systems. The GPS and GNSS breakout is an essential component in many electronic systems that require precise location and timing information.
