HGLRC M100-5883 GPS Compass Module, Upgraded 10th Generation Chip Compatible with FPV Fixed-Wing UAV

This thing is TINY, and it works super well. I needed a decent GPS for a ROS2 project, and saw this after doing some digging. Its quite popular in the ardupilot community. I had no issues getting both the GPS and compass working with ros2.The GPS locks on crazy fast even inside my house which caught me off guard. My experience with other GPS chips has been hold it up high and maybe it will lock after a while if you are testing inside. I had to verify the accuracy it locked on so fast, and it was spot on. I will likely buy this again if I happen to need another GPS chip.

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.

Great GPS reception...can lock onto satellites very quickly and I usually have 15-20 locked in several seconds.

Works great

The best place to mount this damn thing is on the arm of your quad with some racing wires underneath it and some clear shrink tubing. Less interference from your '3 Vista or '04 air unit or whatever you're flying. Most people fly digital screw analog this will help you return your investment when you go out of range or just fail safe from going behind and mountain building whatever GPS returned you home range or for every drone that you build and I found the best place to mount them is on the arm of your Quad

Pros: good pricing, lock quickly.Cons: pinout order is inconsistent comparing to other vendor; False advertising about min voltage 3.3V, does not work at all at 3.3V. It requires at least 3.7V to operate normally.

Nice quality GPS. Locks on 12-18 sats. I'm not neccessarily using it for a drone build at the moment, more of an experiment but it's doing what I need it to. Nice chip.

not sure what is going on with last batch of the units ... i have the same unit on 10+ drones and Compass use to be fast and easy to setup .. now i putting in in a same drone and all i should need is to run calibration ... but its not working .. maybe defective .. ok... send it for a replacement and other one dong exactly same thing..will not caliberate... plug the one purchased 3-4 moth ago and all works just fine...
