It's a very quick fix with a small footprint. I soldered an angle connector to the holes in front of the socket in order to use the module with the Arduino, as shown in the attached photo. It's worth noting that the default baud rate for the unit I received was 9600, not the 38400 listed in the product description.

The device was delivered on time. I set it up correctly with a 3 at the end of the time. lab with 3 volts current supply is in short supply. The supply was set to a maximum of 150 milliamps. After about 30 seconds of booting, the module acquired a fix and output position data correctly. The overcurrent breaker tripped a minute later. Oops. I increased the current limit on the supply, assuming that the processor would require more once it had some data to process. Nope. It happened once again. On the third try, I increased the overcurrent to around 400 mA, and purple smoke appeared. The game is now over. As a result, the item will be returned for a refund. It gets two stars because, with poor satellite visibility, it took a long time to fix the first time, and IF it worked long-term, it would get three stars. The term "UAV/FPV" would have been ideal for my project. If you don't test these things out on the bench first, you might end up with some unusually bent pieces.

Very sensitive GPS that can easily get a fix indoors, which my handheld GPS can't. It's important to note that the compass and GPS outputs are separate. Tx Rx is used by GPS, which generates NMEA sentences. Compass uses I2c to generate integers proportional to the magnetic field's X,Y,Z directions. Only when the unit is level can the compass output be converted into a direction. To create the equivalent of a gimbaled compass, you'll need an accelerometer. The compass and GPS are both functional, but it's better to think of this as two separate devices sharing a power supply rather than one integrated unit.

There are no instructions included, but they can be found on YouTube. Keep in mind that it must be installed "backwards"; It is necessary to place the side with the small silver button on top. It's the antenna, of course.

It performs exactly as I anticipated. There are a few things to consider. First, my controller's wiring harness isn't set up properly. It's a tad on the small side (1. The second issue is that it can take a few minutes for the GPS to acquire enough satellites to acquire fix the first time out for the day, so I had to remove the plug and hard solder directly to the board, which is easier than trying to redo the JST connectors but still difficult. After that, it could take up to 30 seconds each time, which is a little longer than anticipated.

Because the small standby battery is dead, it takes a long time to gps fix the first time you use it. It is natural for it to die after being left for more than two days. Then, once it has found a solution, the next set of batteries will be almost instantaneous. They work great for iNAV and gps in betaflight, but they're very fragile. I just wish it could be mounted in a protective case or that it didn't need to be mounted on top of the quad to function properly.

This thing is thick, warm, and precise (I'm not sure why I'm rating those qualities in that order). What it isn't: serial is slow, and you're better off using systems that can use faster communications channels for high-speed arduino projects like planes or rockets where you need telemetry data quickly.

It's easy to wire and a breeze to transport. It is capable of quickly tracking satellites. This is the GPS that I use the most.
