This FPV NEO-M8N GPS and compass module is a Naza-M GPS/compass upgrade for DJI Naza-M V1, V2 and Lite flight controllers. The listing describes a new generation GPS with low power consumption and high precision, with an ultimate accuracy of 0.6 metres (about 0.9 metres in practice), better than the previous generation NEO-7N at 1.4 to 1.6 metres.
It supports GPS/QZSS L1 C/A and GLONASS L10F, and uses a 32-bit processor that the listing says is superior to an 8-bit one. It comes with a soft silicone gel cable of 30cm wrapped in black rubber for flexibility.
A metal foil label is mounted on the bottom of the GPS to reduce signal interference from other electronic equipment.
GPS and compass on board: one module for position and heading.
Pre-configured: flashed with correct settings, tested plug and play.
32-bit processor: compatible with V1 and V2 flight controllers.
Soft silicone cable: 30cm, wrapped in black rubber.
Interference reduction: metal foil label on the underside.
Multiple connectors: 6-pin for MEGA BLACK, 4-pin GPS only, 4-pin compass only.
Configured output: 115200bps, 5Hz, GGA, GSA and RMC frames.
Super bright LED: shows module status.
A GPS module listens to signals from navigation satellites and works out its position, speed and time. A flight controller uses that position for modes such as position hold, waypoint missions and return-to-home. A compass on the same board gives the heading, so the controller knows which way the aircraft is pointing.
Mount the module as far as practical from motors, power wires and video transmitters, with a clear view of the sky, and let it get a full satellite lock before arming. Poor mounting is a more common cause of GPS problems than the module itself.

The listing says the cable colours are black for GND, white for TX, yellow for RX and red for 5V, and that 3.3-7.5V is acceptable. The specification table gives an input voltage of 3.5 to 5.5V, so power it from a regulated 5V source to stay inside both ranges.
The title and description refer to the NEO-M8N, while the specification table names the u-blox NEO-7M as the chip and model. Because the listing is not consistent, check the exact receiver with the seller if it matters for your build.
