GPS Compass Module+ NEO-M8N+ GPS BDS Module Precision APM Drone Control, GPS Receiver FPV Flight Control Pixhawk Navigation Module for APM PIX PX4, Compatible with APM Port I2C MWC

Using an FTDI TTL USB converter to connect to Windows 10 and Raspberri Pi 3B+. Wired it up and it just works. Used the U-Blox U-Center software on Windows. Surprised I was catching 10 satellites and 3D lock on my desk! Using U-Center, I was able to make some tweaks I needed.Using this for an APRS radio project. Works great with gpsd on Linux.

Bought this as a drop-in, 1-on-1 replacement for a seemingly identical product used in an AHRS from Helios Avionics that was an out-of-the box failure and where the manufacturer Helios determined that the GPS receiver was faulty.It helped that the two GPS receivers not only looked identical, but that also the connectors, the wiring of the connectors and the Baud rate (here 38,400) was identical.There is no documentation for the GPS receiver. However, the product description on Amazon says that the default Baud rate of this receiver was 9,600 Baud. That is incorrect, the Baud rate - at least for the part that I received - is 38,400.The product description also says that it "is easy to adjust", but doesn't say how.I knew however how to adjust the Baud rate that the AHRS was expecting (remember, I assumed that new GPS receiver was sending 9,600 Baud). With a bit of trial and error, I could confirm that this GPS receiver indeed sends at 38,400 Baud, and no further adjustments downstream were needed.With this new GPS Receiver my Helios AHRS now works fine.

A six pin connector is not included.It shows a two and six pin connectors on the gps that is advertised.

Was expecting the Neo M8N but instead got NEO -M10Seems very good.Default baud rate is 38400 and not typical 9600.Getting 26 satellites inside my house while receiver is on my desk.

Removing one star for the lack of documentation and the inaccurate / outdated product description. Maybe it isn't an issue for the Pix/PX4, but anyone intending to use this with a raspberry pi like I was will hopefully find this review helpful.First, the GPS module is not the uBlox NEO M8 but rather the NEO M10. I can't seem to find any documentation on the NEO M10 on uBlox's website, but maybe that's because it's new. It otherwise seems legit. For the serial interface, the baud rate is not 9600 but rather 38400 and it uses 7 bit bytes instead of the usual 8. Haven't tried it with the windows U Center software, but PyGPSClient can parse the NMEA frames without issue once those two settings are updated. Performance is impressive, with fairly quick lock from cold start even indoors.Second, the magnetometer chip is not the HMC5883L but rather the IST8310 (which includes temperature sensor output as an unadvertised feature) and the I2C address is 0x0e and all the measurement registers are different as well, so any code written for the HMC5883L won't work with this device.Documentation issues aside, it's a dandy little GPS puck that integrates well into hobby projects beyond just drones. With a crimping tool you can replace the JST connectors with DuPont connectors to interface directly with Arduino or Raspberry Pi GPIOs. Too bad there's no option to buy them directly with DuPont connectors. Will probably buy several more now that I know how to use them. Only wish the cable was longer.

Works great for my needs. Running at 5hz output it gives me the accurate speed output I was looking for, even without the best view of the sky.

A nice, small, thin package for outdoor DIY projects that use GPS micro controller projects. It even has the newer uBlocks M10 UART GPS with an older I2C Compass.1) You'll need to wire up a FTDI USB adapter to get it working using uBlock's free PC tool and programmer. That uBlocks rabbit hole with that tool is kinda fun and cool in itself :)GPS functionality alone is great. TIP Set it to 115,200 baud in Ublocks vs standard slow 9,600 baud for your projects!2) COMPASS - There are duplicate colored wires for the SCL/SDA I2C compass parts (that you have to unwind). The older compass chip works and has lots of code out their for 2D compass (flat X,Y use). For my autonomous boat (UAV) "flat world" use-case this was not a problem. But you will need scour longer than I did on downloading and testing with over 2 dozen projects, or write your own code to incorporate "tilt compensation" properly for the Z axis on this chip.

I was excited to install this GPS and Compass module on my custom quadcopter build. The GPS functionality never worked and I wasn't able to get a fix on any satellites. However, the compass did work. I eventually connected by system with the same wiring to a spare M8Q module I had and the GPS worked fine. I must've gotten a defective module.After opening the case and verifying the connections, the GPS module started working.
