Description

**3.3 VOLTS ONLY - DO NOT USE 5 VOLTS!**

We recommend an input voltage of 3.3v. The result may not be immediate, but eventually supplying voltage out of component limits will kill it. Always verify prior to install that your system is giving the GPS the voltage you think it is via a multimeter. If your unit dies or fails to operate as you'd expect, this is likely the cause.

The RDQ Mini M8N GLONASS GPS Module is 18x18mm in size, perfect for any Micro , or add Gps to your racer to add "lost tracker" . Only 6 Grams with cable.

Note: Providing the GPS with over the spec'd voltage WILL destroy your unit.

Joshua Bardwell says: "In the video above, I mistakenly power the GPS with 5v. The GPS needs 3.3v power, not 5v. Powering the GPS with 5v will destroy it."

How to add a GPS in Betaflight 3.2

With the 3.2 release, Betaflight finally has decent GPS support. Here are some of the navigation features you can have on Betaflight OSD:
  • Latitude
  • Longitude
  • Distance to home
  • Speed
  • Arrow pointing home
Even better: if you have a telemetry-enabled receiver such as the X4R or XSR, you can send your location to the Taranis in real time. The Taranis will log your position, and keep the last known position available in case of a crash. This means it could save you time and maybe money in the long run. This unit comes preconfigured and ready to wire to a flight controller. However, if you want to mess with the settings you can configure it via a serial UART and u-center for Windows. This video is still mostly relevant if you need to do that. Wiring the gps unit is easy: just connect it to a free UART on your flight controller. Make sure that the wires are long enough that you can mount the gps on top of your quad.  If you are running a bottom mounted battery, the top of your HD camera mount is the best spot. I run a top mount, so I prefer heat shrinking the gps to a battery strap so I can have it on top of the battery. Once wired, configuring the gps is easy.  On the ports tab of Betaflight, select gps as a peripheral for the UART to which it’s wired. In this case I used UART 3.
Then in the configuration tab:
And if everything is wired correctly, when you restart betaflight you should see the GPS indicator light up at the top of the screen. Now there are two things you can do. If you have Betaflight OSD, you probably want to enable gps coordinates, distance to home and direction to home. I also like having the satellite count and gps speed, even though it’s not very accurate. My screen looks like this:
The home arrow indicates that I’m flying mostly away from myself and 145 meters away. The GPS coordinates show that I am in… [left as an exercise for the reader]. The second thing you could do is set up your Taranis to log gps coordinates (assuming your receiver has telemetry, won’t work with an xm+). I won’t cover that now because this is enough for one post, I’ll save it for a future one. Happy flying and hope this saves you from losing a quad or two!

Reviews

Works great had to solder

"Works great had to solder to the fc couldn’t use the plug that connects to the fc."

Jonathan C. (5/5)

Old faithful!

"Old faithful! I've bought a million of these. Always works"

W J. (5/5)

Hard to beat for the price.

"I've bought a few of these and they work pretty well. After about 6 months of working fine, one of them just stopped locking sats, so I just replaced it and all is good. Been searching the interwebs for anything I might do to bring the broke one back to life, but likely a dead sensor so I'm not optimistic."

doug o. (4/5)

Really happy ..

"with this gps. Can't beat the price, and even on a cold start usually has the minimum sats in <30 seconds. GPS rescue works as expected. Really good value compared to modules I've seen costing almost twice as much."

Rdq gps

"Great lil sucka on 3.3v. Quick acquisitions. Solid gps"

Jeff C. (5/5)

The Only GOS I use anymore

"Install is easy. Module is small and fits on even my 2.5 inch LR quad. Setup in BF is a breeze. I put these on all my LR quads now. Make sure to connect it to 3.3v not 5v and if it doesn't work on the UART try a different UART."

Stephen S. (5/5)

Great little gps. Works awesome.

"Great little gps. Works awesome. I just tested gps rescue and return to home failsafe and it worked flawlessly."

Edward W. (5/5)

Quality

"Easy to in stall small in size works very well,highly recommend."

RDQ Micro M8N GPS with Matek F411 wing FC

"Lucky the F411 has the 3.3 volts required for this GPS . This information is critical and not well documented. Make sure your FC has the 3.3 volt source for this product."

Robert T. (5/5)

Easy setup

"It works and I got satellites right away. Plus there are some videos online for installation of this model."

Q&A

Can these be used with dji air unit?
Yes it can!
I purchased one of your mini gps boards that needs 3.3 volts, how do you do this when my flight controller outputs only to 5 volts?
You would need to add a BEC to your build to regulate the voltage down to 3.3v.
