We have designed new board based on the Ublox NEO-M8N module.
The NEO-M8N Evaluation board makes evaluating the high performance of the u-blox 8 positioning engine simple. With a built-in USB interface for both power supply and high-speed data transfer, the need for an external power supply is eliminated. The NEO-M8N Breakout board is very compact, and it’s user-friendly interface and power supply options make it ideally suited for use in laboratories, vehicles and outdoor locations. Furthermore, the NEO-M8N breakout board can be used with a PDA or a notebook PC, making it the perfect companion through all stages of design-in projects. It’s a fully assembled and tested PCB for the u-Blox NEO-M8N with SMA antenna connectors.
NEO-7N breakout board features:
- 72-channel u-blox M8 engine GPS/QZSS L1 C/A, GLONASS L10F, BeiDou B1 SBAS L1 C/A: WAAS, EGNOS, MSAS Galileo-ready E1B/C (NEO-M8N)

Did you try module from csghop.com ??
I'm also struggling with a NEO-M8N + HMC5983 from DroTek to get it to work with a Pixhawk.
Ublox NEO-M8N GPS + HMC5983 compass
The moment I change it to UBX protocol and 38400 baud it does not work at all anymore!
Only 3 or 4 sats are receiving and this is not normal, my LEA-6H is out preforming the neo-m8
I wil try some tests this evening before I send it back.
Can someone please post a GNSS file from a corretly working NEO-M8 with Pixhawk?
Is there a housing available similar to as shown here from HK for the Neo 7?

I changed the settings as recommended on the previous page of this topic. So it's 38400 Baud. But I had to set the protocol out to UBX + NMEA, because setting it to only UBX broke both USB and UART connection in u center. And after repowering the module, the configuration was lost (maybe it wasn't stored properly to the EEPROM at all due to prior connection lost). But with UBX + NMEA configuration works fine.
By the way, the jumper on the backside has also been resoldered to the "UART"-side.
what baud rate you use for data?
Hi,
is there anybody, who figured out how to solve the problem with the data stream glitches mentioned above at 5 Hz navigation rate? I'm setting up my Neo-M8N right now and also found the data stream not to be stable at 5 Hz, althoug the receiver is specified for that rate.
Finally have mine working again - phew :-)
Ok, I figured out how to make the manual changes:
1) Connect to the device.
2) Open View / Messages View (Hotkey: F9).
3) Select UBX-CFG-PRT.
4) Poll the current configuration from the receiver ().
5) Change the setting to the desired
6) Send the message to the receiver ().
I've manage to bugger up my M8N, when I first turned it on it seemed to work fine. But for some crazy reason I thought putting the 3DR software on there would help, now it seems to take forever and doesn't lock. Would somebody kindly download there GNSS file for me and I can start over. Fingers crossed - CHeers, Mike
