HGLRCM100-5883 GPS Compass Module, Upgraded 10th Generation Chip Compatible with FPV Fixed-Wing UAV

A Tiny Titan for FPV BuildsI've been building FPV drones for a while now, and the HGLRCM 100 GPS unit has become my absolute go-to for reliable positioning.Pros:Lightning-fast Satellite Lock: Compared to my old BN-880, the HGLRCM 100 acquires a lock in what feels like half the time. It's ready to fly almost as soon as I power up.Rock-solid Tracking: The GPS tracking is incredibly accurate and maintains a strong signal even during aggressive maneuvers. My old BN-880 used to drop satellites during aerobatics, but the HGLRCM 100 just keeps chugging along.Compact Size: The small form factor makes it easy to fit into tight builds.Integrated Compass: No need for a separate compass module, which saves space and simplifies wiring.Cons:wiring: First time I wired up this unit I put the wiring harness in backwards there's one side that goes to the GPS unit and one side that goes to the flight controller however they are not labeled so be careful and watch out.Overall:If you're looking for a top-notch GPS unit for your FPV builds, the HGLRCM 100 is a fantastic choice. It's fast, accurate, compact, and reliable. Whether you're flying freestyle or long-range, this GPS won't let you down. I can't recommend it highly enough.

Works flawlessly on my Pixhawk 2.4.8. Quick sat acquisition.

Works good , i tried two other brands of gps that didnt work .Gets signal quick and maintains around 20+ sats. Buy now before the trump tariffs drive up prices.

This gps and magnetometer is solid and saved my drone from crashing on the houses below. The magnetometer works as expected. The gps rescue is reliable on this m100-5883. 5 stars now“””””I would give it 5 stars. The GPS locking is insanely fast. But Betaflight can’t seem to detect the compass. I did double triple checked all the connections, wires & voltages. All seems normal. I bought 5 units and I opened 2 of them so far. Both aren’t being detected by BF.”””””What am I missing?Will update the review and stars after seller contact.

Other reviews suggested it wouldn’t work with their flight controller, but it seems likely they did not wire it correctly. The cable it comes with needs modified/re-pinned for your FC. TX/RX need swapped, and the SCL/SDA pins are straight through. When wired correctly and baud rate set to 115200, it is auto detected by ardupilot, and calibrates as normal. Gets 3D lock in a few seconds inside my house. I’m using it with ardupilot and a speedybee F405 wing app.

So I, like many, believed the good reviews and the fact that this device has the same part number as Matek GPS's do and bought some because the price is so good compared to the Matek. Well that is where the similarity ends - every last one that I tried took a full 3 plus minutes to find 4 satellites and after 5 minutes hadn't locked on the required 6 to arm the bird. And even after "locking on" it lost satellites so fast that I usually can't maintain a lock that allows me to use autolaunch. So if your application isn't for a flying machine you might be fine but if you want to use this to save your aircraft in the event of an emergency it will likely cost you your plane/quadcopter as its poor quality defeats the whole purpose of it.

Well ordered wrong size but a friend will use go his drone

Very fast functioning. Easy installation and great value 😁 i do plan on getting another
