- Make sure this fits by entering your model number.
- BN-880 is suitable for Open source flight controller, not for flight control with SCM
- Bn 880 gps module is dual module compass, with and electronic compass IC HMC5883L
- Bn 880 gps module has flash to save configuration. So you do not need to reset next time when you use it
- DIts data Level is TTL or RS-232, Default TTL level. To make it be RS232 output, you need to use one TTL to RS232 converter cable
- When you use it for Raspberry Pi, there is no driver needed but you need to install software

Geekstory BN-880 GPS Module U8 with Flash HMC5883L Compass + GPS Active Antenna Support GPS Glonass Beidou Car Navigation for Arduino Raspberry Pi Aircraft Pixhawk APM Flight Controller
- 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.
- 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.
- The first time you use it, it takes a long time to gps fix because the little standby battery is dead. It will always die after being left more than 2 days, this is normal. Then after it finds a fix, the next batteries will be almost instant. These work excellent, but they are extremely fragile. They work for iNAV and gps features in betaflight. I just wish you could mount it in a protective case, or it did not have to be on top of the quad to work correctly.
- 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.
- 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.
- Bn880 performs fine only buy if you actually need compass for drone bn220 gps is better
- 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.
- It comes with no instructions, but you can find them on Youtube. Be aware that it needs to be mounted \"upside down\"; the side with the little silver button needs to be on top. It is the antenna.
