Meet the SparkFun GPS-RTK Dead Reckoning Breakout - ZED-F9R , your go-to GPS module for precision navigation in tough environments. This cutting-edge GPS receiver fuses sensor data with GNSS signals from GPS, GLONASS, Galileo, and BeiDou, delivering an impressive 0.01-meter accuracy when paired with an RTK correction source. The ZED-F9R combines u-blox's Automotive Dead Reckoning (ADR) technology with a 3D IMU sensor, wheel tick data, vehicle dynamics models, and GNSS corrections to provide a continuous, reliable positioning solution—even in dense urban landscapes or areas with limited signal access.

The 184-channel u-blox F9 engine enables this module to operate with four GNSS systems at once, keeping you connected and precise in real-time at rates up to 30Hz. Whether you're navigating tunnels, parking garages, or urban canyons, this module guarantees you won't get lost.

Perfect for autonomous robotics, the ZED-F9R features a built-in Qwiic connector , meaning no soldering is required to hook it up to your system. However, the board also includes 0.1"-spaced pins for breadboard compatibility, offering ultimate flexibility. Want even more control? The module is fully configurable using u-center software or SparkFun's Arduino library , allowing you to tweak baud rates, update rates, geofencing, spoof detection, and more.

A cold start takes ~24 seconds, but thanks to the onboard rechargeable battery , you can enjoy hot starts in just ~2 seconds. The SparkFun ZED-F9R is a top-tier choice for anyone who demands precision and performance.

Lightweight and comfortable
Size: 42, Color: Kangaroo, Size: 42, Color: Kangaroo
The fit is just right and they're very comfortable. This is the second pair I've bought and the review could easily be for both pairs. The only difference between them is the color. I deducted a star because they really need at least 2 more belt loops. Why do manufacturers skimp on something that would be so inexpensive to do right? The belt loops on either side of the front button are 11 inches apart. Ideally they'd be at most 5 or 6 inches apart. Anyway, these will be the shorts I wear to do my yard work. I can put my phone in the right hand cargo pocket and know that the Velcro closure won't let it fall out while I'm working. My keys will go in the left side cargo pocket. I'd definitely buy them again. The price is right and they are comfortable to wear.

Very well designed shorts!
Size: 36, Color: Gunmetal
Bought one pair awhile ago, and now buying several more. Great relaxed fit, very comfortable, good fabric weight AND pockets not designed by morons - actually so easy to store and retrieve wallet and phone unlike Dockers and Izod and other cargo shorts I've purchased in the past. So comfortable and well designed. They're cut a little large for the stated size - but not necessarily a bad thing, and waist has a little bit of stretch. Love them!

Once you put them on, you will know you made the right decision
Size: 38, Color: Medium Tint Denim
Absolutely perfect in every way. Staring either the very reasonable price, the true to size fit, and quality. Hip pockets are deep, and can come in handy. Most don’t know that Wrangler actually started in 1904 as a company called Blue Bell, and later renamed Wrangler. Well established and a long history of top quality clothing. Although you may find another company selling for a bit less, that’s what you’ll get……Less !!?

Good shorts but they run big
Size: 38, Color: Dusty Olive
I've been losing weight and picked these up in my new size (38). It turns out these are cut for a generous American midsection, and have an elastic fit in the waist, so you can (and probably should!) safely go down a size. I got mine in 34 instead and they fit great.

Great fit, functional, most comfortable shorts!
Size: 30, Color: Anthracite Camo
These are my go-to shorts, I now have five pair in different camo colors! I suggest one waist size smaller than you normally wear, (I buy a 30 instead of a 32, because they stretch and would be too sloppy if I purchased my regular size). The large open slotted pocket on the left, behind the Velcro flap pocket, is perfect for a normal sized cell phone. Plenty of utility pockets for EDC. Since these stretch slightly to accommodate movement and sitting, they are extremely comfortable. Also, my wife says they are good looking on me, so that gets an extra star!
