HGLRC Mini M100 GPS Module for UBLOX Compatible with 2-7 Inch FPV Racing Drone

For the size, it has an ideal build quality and range, picks up GPS signal under 5 min. As a side note, it does come with a very long cable, you most likely will not need to purchase separate cable, it does come with a connector which I had to cut and solder to the board. Tested on a Pavo 20 Pro 2

Recommend, good quality, small size and weight, basic functional as a big GPS module, but small enough to put it on a 3inch drone. Just watch if the price not too high, buy it. I bought for 18$, but I think this would be better for 12$ or 15$.

Locks 8 sats in my 1st of 3 floor condo, in Alaska. Have 4 of these installed on my FPV quads and they all work perfectly. They are a little slow when they first try to connect in a new area. They usually take around 2 to 3 minutes for it to lock in 7+ sats (i can fly on 5 but have it set up to only arm on 7+ locks). once it locks them for the first time, it can reconnect within a few seconds after power cycling my quads. I consistently have 12 to 17 satellites locked at all times outside. I have never had it drop signal or fail. So far, I could not be happier with my purchases. In fact I'm on here right now with the intent to purchase two more, and I figured that since it is such a good product that I should give it a review....so here we are.

The stock M8 is still a good GPS, but it was giving me some connection issues on BF 4.4.2 with my Zeus10 aio (Target "ZEUSF4EVO") on the Rekon35. It was a shot in the dark, but I upgraded to this M10 and got 12 sat after 2~ minutes on the ground. 20 sat locked after about 1 minute of flying. First test of GPS rescue landed within 5 meters of the home point. I'm super happy with this tiny M10 GPS unit! A few notes that may or may not be relevant. I copper tape warped the wires, than covered them with heat shrink. I ran the 5v and ground to the receiver 5v and ground so I can power the GPS when plugged into USB as well as battery. This will also allow you to "warm up" the GPS with a power bank before powering the whole quad and cooking your VTX. Alternatively you can flip your VTX into pit mode for a faster GPS lock when at a new location.

Replaced the trash Goku my quad came with. Old GPS took forever to get a lock and never worked right. This thing fired right up and locked within 5 mins on a cold start. Very nice. These things just work.

First off. This thing is tiny. Makes it perfect for placing it on 3 inch quads and other smaller freestyle drones. The small size also means lighter weight which is great for racing, and just saving weight in general. As far as performance, I've been pleasantly surprised. So far I haven't encountered any issues, in fact it picks up and holds around 16 satellites whenever Ive flown. The HGL M80 Pro, which I use one another quad, averages around 7-8 satellites during a flight. The only thing that could be better is that the QR code to get to the instruction manual doesn't work and takes you to some sketchy website that my virus software didn't like at all. If they would just include a printed instruction sheet I'd be much more happy. You'd think they would have links to the manual on their website, but I couldn't find anything like that. All in all though, once you figure out how to set this thing up, it's awesome and I highly recommend it.

Bought one of these to cram into a meshtastic enclosure and it is absolutely MINI! This thing can't be bigger than the size of a nickle, yet it's able to connect to just as many satellites as my other modules?! That's insane to me. For the price and size, I am not sure it can really be beat, at least as far as modules you can get off of Amazon. Definitely worth it. LEDs on the back of the antenna are very bright and easily shine through 3D printed plastic (if that's your thing). Wiring to the module was already done out of the box, I just snipped off the grove connector and hooked it up directly to a Heltec V3. Been running that combo with a 2000mah battery for a few days now with about 20% battery remaining, shockingly so I feel the power consumption is a little better than the other boards I was using before. Super worth it for the size, cost and performance of this little guy!

No faster acquiring satellites than others from inside my cabin. I have a number of the cheapest type plus one more expensive moulded ufo-style one intended for drones. All of them work about the same and acquire satellites in roughly the same 10 seconds or so. I bought one of these just to see if there was a big improvement, but there wasn’t for my use which is making time-sources for clocks and private ntp servers.
