This UBLOX Micro M8N incorporates the HMC5883L digital compass, using the Ublox latest series module providing a convenient method of mounting the compass away from sources of interference that may be present in the confines of your vehicle. The M8N features active circuitry for the ceramic patch antenna, rechargeable backup battery for warm starts and is shipped pre-configured for use with Pixhawk.
The NEO-M8 series of standalone concurrent GNSS modules is built on the exceptional performance of the UBblox M8 GNSS GPS, GLONASS, Galileo, BeiDou, QZSS and SBAS engine in the industry proven NEO format.
The NEO-M8 series provides high sensitivity and minimal acquisition times while maintaining low system power. The NEO-M8N provides the best performance and easier RF integration of all the NEO-M8 configurations.
The NEO form factor allows easy migration from previous NEO generations. Sophisticated RF-architecture and interference suppression ensure maximum performance even in GNSS-hostile environments.
NEO-M8 combines a high level of robustness and integration capability with flexible connectivity options. The future-proof NEO-M8N includes an internal Flash that allows simple firmware upgrades for supporting additional GNSS systems.
The DDC (I2C compliant) interface provides connectivity and enables synergies with most Ublox cellular modules. For RF optimization the NEO-M8N features an additional front-end LNA for easier antenna integration and a front-end SAW filter for increased jamming immunity.

You aren't going to find a GPS with a genuine uBlox NEO-M8N chipset anywhere.
This "holybro" model differs from their round version only in the pin order and connector.
It's not a Taoglas patch antenna, but the assembly of the entire unit is first class.
For use with a pixhawk, you'll need to refer to the pinout I uploaded to reorder the wiring.
Before even leaving the ground, my units are already tracking 27 satellites.
Before finding this gps, I tested over 10 others which all turned out to have cloned chipsets and on some of them, luck was the only thing keeping them held together.
Fake units do not have flash ram, which will prevent you from being able to upgrade to the 3.x firmware. The flash also keeps yours settings, allows downloading of ephemeris data, and enabling the data log. Genuine units also have a unique signature on each; you can check that via the uBlox app, and all the other settings and options can be modified through the app as well.
The only negative thing is the appearance of the case. The raised solder blob on the antenna caused crazing on the lids of most of these I purchased. Of course, it's just cosmetic.. they will probably crack after a while, but so far, none of mine have.sadly not satisfied.
I used this unit on my nova/cx-20
unit is not labeled for pin-out.
After figuring out the pin-out the unit works and find satellites fast!
my stock GPS usually has 9 satellites. the quad drifts about 5 meters.
Today when testing the m8n, i did have 15.
Sadly the quad was not stable and drifted/circled about 20 meters.
So even with more satellites visible it is not able the hold a steady position.
Did buy one to setup with F3 control board from HK. Once the wiring is sorted out, it works pretty well and gets the satellites fast. Will fit perfectly on the robocat 270 mm. There is a green led for the power and a blue led to identify when the sattelites have been detceted. I can't wait to test that in the air!
