The NEO-6M is a u-blox 6 GPS receiver that outputs position and time over UART using NMEA and UBX protocols. Distinguish the core module from a hobby breakout that may add a regulator, antenna connector, and backup components.
Key specifications
The u-blox data sheet describes a 50-channel receiver, nominal 2.5 m horizontal accuracy under test conditions, and a maximum 5 Hz navigation update rate for NEO-6M. Buildings, antenna quality, interference, and sky obstruction can reduce real performance.
How a fix is calculated
A full three-dimensional navigation solution normally requires at least four satellites to solve latitude, longitude, altitude, and receiver clock bias. Three may support a constrained solution with a known altitude, but not the general full 3D fix.
Power and serial wiring
The bare NEO-6M module has a low-voltage supply and a 3.6 V absolute maximum. Some breakout boards accept 5 V at a regulated input, but this is board-specific. Follow the exact schematic, connect module TX to controller RX, and use level translation where the reverse data path requires it.
Antenna and output
Antenna type and connector depend on the breakout. Some include a patch antenna and others support an active antenna. The common default serial setting is 9600 baud; inspect NMEA directly or parse it with a library such as TinyGPSPlus.
