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

Excellent Budget Gaming Monitor
Size: 24.5" 200Hz/FHD
I’m very impressed with this monitor for the price. The 200Hz refresh rate makes gameplay feel incredibly smooth, especially in fast-paced games. The picture quality is sharp, colors look good, and the screen size is perfect for both gaming and everyday use.

Better off saving your money for a quality brand like Acer or Samsung
Size: 24"/FHD/240Hz
If you were looking for a decent gaming monitor with a good refresh rate, you better keep looking. Honestly, I wanted to really like this thing. For $120, it ticked off a lot of great features for me: at least 120Hz refresh rate, 1080p quality, and some nifty reticule marks for FPS gamers like myself. And for a year I had no problems with it until a few days ago. The ability to control input's, power, and toggle the reticule features all lie on one singular button behind the monitor. Here lie's the issue; if that power button starts messing up, there is no way to control or turn on/off the monitor. This is exactly what happened on my unit; the power button/control went out and the monitor was basically useless. I contacted Koorui support via email, and all I got was a vague "Did you confirm the button is really broken" response. Replied back that I did, and the manufacturer has ghosted me. Basically, I HIGHLY advise you just save up a few $80 or $100 dollars and get a decent entry level gaming monitor. By going cheap with this one, you will just end up probably wearing out the power/control button and be left with an expensive paperweight. If you are DIY repair savvy, I am sure that replacing the power/control button probably is not that big of a deal. In which case, go right ahead as it is a decent monitor for the price. But with that said, having this thing break leaves you with basically no options to get it fixed and good luck trying to get a hold of Koorui for support. Sadly, this is a growing trend on buying electronic's here on amazon from smaller brand sellers. *Update* So as of writing this review, I got Koorui to reach out to me. They would agree to replace the monitor for free, but I would have to front the shipping costs. They have their operations out in California, so if you live on the east coast then expect to pay around $40-50 for shipping for the monitor all the way out there (nearly half the monitor's value). I told Koorui that this just did not make any financial sense and they offered to refund me 50% of the monitor's value. However, they have yet to specify how they will send the refund, so I am unsure of whether I will see my partial refund when this is all said and done. So know that if you do proceed to get this monitor and need to return it past the 30 day return window covered by Amazon. TLDR: just save up an extra $50-100 for a big brand gaming monitor and save yourself the headache of dealing with all of this.

I feel fully enveloped in the work
Size: 34"/WQHD/1000R/HDR400
Changed my work at home experience. I feel fully enveloped in the work. I don't use it for gaming so can't comment on that. But for laptop heavy work days, this is a great experience.

Simple and not Drama claim process.
’ve had Asurion coverage for a couple of years and never needed to use it until recently, when my pool salt cell (less than two years old) stopped working. I had purchased it with an Asurion protection plan, so I contacted them to start a claim. The process was simple and straightforward to follow. In the end, they honored the plan and covered the cost of my salt cell based on the value when I originally bought it. They issued me a gift card that I could use on Amazon for that amount. While prices have gone up and a new cell now costs about $200 more, it was still definitely worth having the coverage. Overall, I’m satisfied with how the claim was handled.
