Welcome to the future of GPS technology with the SparkFun ZED-F9R GPS pHAT. This isn't just any GPS board; it's a high-precision, sensor fusion marvel that boasts top-tier configuration options and leverages u-blox's cutting-edge Automotive Dead Reckoning (ADR) technology.

Stellar Accuracy and Performance

Equipped with the ZED-F9R module, this pHAT is a powerhouse. Featuring an 184-channel u-blox F9 engine GNSS receiver, it can tap into GPS, GLONASS, Galileo, and BeiDou constellations, delivering jaw-dropping accuracy of approximately 0.01 meters! This precision is achievable through RTK navigation when paired with a correction source. Keep in mind, the ZED-F9R functions solely as a rover, necessitating a connection to a base station. It supports simultaneous reception from four GNSS systems, and its fusion of GNSS and 3D sensor data ensures real-time positioning at up to 30Hz.

Unwavering Performance in Challenging Environments

Urban jungles and dense areas are no match for the ZED-F9R. This module excels where others falter, maintaining continuous, accurate positioning even under poor signal conditions or complete signal loss—think short tunnels and parking garages. It's the go-to solution for autonomous robotic applications demanding pinpoint accuracy in tough settings.

Easy Integration and Versatile Compatibility

Integrating the ZED-F9R with your setup is a breeze. It uses the Raspberry Pi's serial UART for communication and comes with pre-soldered headers—no soldering needed! Stack it onto a Raspberry Pi, NVIDIA Jetson Nano, Google Coral, or any 2x20 form factor single-board computer effortlessly. Plus, a few 0.1"-spaced pins and a Qwiic connector are broken out for those needing additional connections.

Comprehensive Configuration Options

The ZED-F9R is configurable through the feature-rich, albeit dense, u-center software. Adjust baud rates, update rates, set up geofencing, spoofing detection, and more. Tinker to your heart's content and tailor the module to your specific needs.

Rapid Start with Onboard Battery

Say goodbye to long wait times. The ZED-F9R includes an onboard rechargeable battery powering the RTC, slashing the time-to-first fix from ~24 seconds (cold start) to a mere ~2 seconds (hot start). It maintains RTC and GNSS orbit data even when not connected to power, keeping you ready to go at a moment's notice.

The SparkFun ZED-F9R GPS pHAT is also equipped with an on-board rechargeable battery that provides power to the RTC on the ZED-F9R. This reduces the time-to-first fix from a cold start (~24s) to a hot start (~2s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.

This product requires an antenna: Any GNSS receiver will be fine, this board uses a U.FL antenna connector but you can also use an adaptor if needed

Not too long, not too short in the bum where you have a wedgie allll day long. I've tried soooooo many brands (Amazon probably hates my guts) but I've been searching for months to find some long enough to go over that crease between your thigh and groin. Mine gets soooooo sweaty and then itchy so I needed something to cover and absorb. The larger recommended size settled into my stomach/belly button area and makes it looks like I have the hugest fupa ever! I But like several reviewers before me mentioned-you might as well toss the grey pair. Its like 1-2 sizes too small. Just the grey one! ALWAYS! So I knew to try it on so I wasn't shocked later! Wish they had and all black set (hint, hint), without that weird, bad fitting grey pair. Just get rid of that one! Update 1: they do run big. And yes, liners/pads DO stick. Thank goodness. Update 2: bought 2 sizes smaller than Amazon recommended. Tight when tried on, much better after washing. Very stretchy. Now it's wedgie problem. All day, all the time wedgie. Not good. No one gets that women have butt's that are bigger than the front. So yes, it goes just below my belly button, but the backside barely reaches to the bottom on my tail bone/start of the booty crack. So now my search moves to men's boxer briefs....

Six seams come together between your vag and rear exit. Not good.
I thought these were cute and liked the colors. They were on sale. I was looking for regular cotton boy shorts for women. I am very petite. For some reason it has become very difficult to find regular cotton boy shorts that have a gusset and the elastic band is covered. I do mean that I was just looking for basic cotton slip shorts that I have bought within the last year that have a covered waistband because I get irritation from elastic. Because of the weird data silos that Walmart and other retailers are now using, my purchase history will not pull up underwear purchases in the last year so that I may be able to reorder the ones I liked. I am so frustrated by this but needed to buy more underwear. I saw that the elastic was not covered but thought I'd try them anyway at the sale price because this elastic band is the type that can be folded over if irritation occurs. However, this is the worst fit of underwear I've put on in a while. They are made for a woman with large thighs or rear. There is a gap at the leg holes giving the feeling of breeze/no security at the butt and there is nothing, no tension there, to stop these underwear from going right up and what makes it worse is they must have made these for a woman with orifices right at the front of her pelvis. When you look straight down into the underwear you will see where the crotch gusset ends and the back seam begins. It is straight down! In other words the gusset ends and the left to right leg seam plus the seam going to the back ALL meet at this intersection which is right on top of my back door opening. This problem plus the fact that the leg holes are too big and nothing is holding the underwear down snug around my thighs means the most uncomfortable underwear seam JUNCTION is also going to be riding up my backside. I hate them. Cute colors but these underwear are not for people like myself who I thought was pretty normal despite being petite. I just hate them and I find it really frustrating that I'm going to have to end up sewing my own underwear, which is is a very basic style of underwear, not because they are no longer being made but because Google searches and Amazon searches are so confabulated and leveraged that I can't find them no matter how hard I try. I'm sick of this. I'm absolutely sick of this and UNDERWEAR IS IMPORTANT. I give two stars because they colors are really cute but I hate them and need to put an extra gusset in and try to take up the leg holes.
