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

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!

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.

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$.

All these m80s-m100s / GPS units in the last few years are ok at best- glitchy and not very reliable when most needed. Maybe INAV is better than cleanflight/BetaF, but it works like all the rest. skystars aio45amp J was the flight controller also I soldered it in to Lux f7 mini FC worked perfect.

works good for a mini. takes a few minutes for 12+ sats but when it finds them they stay locked. Good product for my 2 inch drone

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. Ports Tab Baud Rate set to 115200 Config Tab GPS: UBLOX Protocol, Auto config On, Auto Baud On, Use Galileo On, Set Home Once On, Ground Assist Auto detect.

Works fine set to UBLOX 38400 kbps Running inav 8.0 on an f405

Gets a lock very fast compared to their larger m100 unit, while being a quarter of the size. the only downside is there is no compass built into it, but that is a non issue in my case since I am using it in a fixed wing drone, but similar could be said for arduino projects, mesh nodes, etc
