BN-880 GPS

Very sensitive. GPS which easily gets a fix indoors, something my handheld gps cannot do. Note that the compass output is separate from the GPS output. GPS uses Tx Rx and outputs NMEA sentences. Compass uses I2c and outputs integers that are proportional to the X,Y,Z magnetic field. The compass output can be converted to a direction, but only when the unit is level. You need an accelerometer to make the equivalent of a gimbaled compass. Both the compass and GPS work well, but it's better to think of this thing as two devices that use a common power supply than one integrated unit.

Great gps, bought 2 for a couple multicopter builds I’m working on to test out experimental gps functions in Betaflight. Gps and compass lock on quickly (after first initial power on). Come’s with a few connector options but for me I was able to solder directly to one flight controller while the other flight controller requires a 6pin jst-sh connector which doesn’t come with this product so I had to find a source for that connector before getting it to work.

Works like I expected. There are a couple of things. First the wiring harness is not setup for my controller. It is way to small (1.0 pitch) to be able to redo the JST connector so I had to remove the plug and hard solder directly to the board. This is easier then trying to redo the JST connectors but still difficult. The second issue is that the GPS can take a few minutes to acquire enough satellites to acquire fix the first time out for the day. After that it may take 30 second each time. This is little longer then expected.

This thing is thick, warm, and accurate (why I’m rating those characteristics heaven only knows). What it’s not, it’s not good for high speed arduino projects like planes or rockets where you want telemetry data fast. Serial is slow, and you’re better going with systems that can use faster communications channels.

Small footprint, very quick fix. In order to use the module with the Arduino, I soldered an angle connector to the holes in front of the socket, see attached photo. Note that the default, out of the box, baud rate for the unit I got was 9600, not the 38400 listed in the product description.

Once it has a lock this works great, however the tiny super cap they use discharges very quickly once power is removed, leading to loss of data and a much longer several minute lock time.

This is a fantastic GPS for FPV. It is simple to wire and very lightweight. It tracks satellites quickly. This is my go to GPS.

The best IOT GPS I have used so far. A few dollars more, but well worth it. Have bought a few now and have never been disappointed.

I faced the same issue with the BN-880 GPS module when using pins 3 and 4 with SoftwareSerial. Despite the LEDs blinking, no data was received in the Serial Monitor. The solution was to connect the RX pin of the BN-880 to TX (Pin 1) and the TX pin of the BN-880 to RX (Pin 0) on the Arduino. These pins use the hardware UART, which is much more reliable for the continuous high-speed data from the GPS module. Additionally, remember to disconnect the GPS module during sketch uploads and reconnect it afterward. If debugging is needed, consider using an Arduino Mega or an external USB-to-serial adapter. Avoid SoftwareSerial for high-speed devices like GPS modules—it’s simply not reliable. This approach resolved the issue for me, and I hope it helps others!

Ich bin voll zufrieden, der Artikel funktioniert genau wie beschrieben.

Works great and locks to sat quite fast

Completely unacceptable. The GPS powers on but never detects any satellites, even outdoors. I wasted hours troubleshooting, testing different setups, and confirming it’s defective. Now I have to waste even more time going to the post office to return this faulty device. Total frustration.

Works as expected. Lost my original in a crash and this was an exact replacement. Warms up quick and locks onto sats quickly.
