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

Great insight on what happened at Blizzard but...
Format: Kindle
My main issue with the book is the lack of non-american stories that explained the bigger picture. As a former Blizzard dev, there's much more than what happened in Irvine and Korea, with Europe's office mentioned almost as a footnote, and nothing else from the other regional stories. Shame but I guess the book would've been double the size.

Insightful inside scoop of Blizzard
Format: Audiobook
An intriguing, well-written exploration of Blizzard’s history and its staff, from inception to modern day, and their design decisions, successes and failures along the way. I loved the many quoted insights, and learning more than just the surface level story that might be found on typical gaming news outlets.

This book really helps organize a process that is inherently chaotic
Format: Kindle
I'm working on a series of novels about a world of talking animals that grows up after humans die out from complications of climate change. Every species has its own culture. I got through the first book and well into the second before I realized that I needed some way to codify all the cultural details. I had lots of ideas, but no way to organize them, and as I moved towards the third book of the series, which would require creating seven or eight whole cultures, I was feeling overwhelmed. Creating Life and the free templates the author provides as a download are proving to be very useful tool. I look forward to reading the other two books in this series, too.

An excellent book
Format: Kindle
I am a new fantasy fiction writer, and the detail of this book really helped me out very much. As I was searching Amazon for a book on this topic, this was one of the few that stood out. The author also offers continuous lessons on world building through his free newsletter, which I also find helpful. I highly recommend this book. Thank you Randy. L.M. Montes

Both books in this series are worthwhile reference sources
Format: Kindle
Great books--I got both this one and Creating Places. I simply stumbled upon both books online when looking for something about plotting, and I bought them both, and am glad I did. I'm a fairly experienced writer in literary genres, but fantasy/sci-fi are different. The first book I got, Creating Places, was immediately useful as I was creating a land ringed with tall mountains, and I wondered about rainfall--this book answered my question about how mountains effect rainfall! It's not like you couldn't look some of this stuff up in other ways, but having it all in one place was very useful to me. This one still had tips I was interested in, but I agree with the reviewer who noted it did feel like it was more about world building for world building's sake (at least in this book). Plenty of things didn't apply to what I'm writing, but if you use these as a handy reference--rather than a "how to" book, I still think there is a lot of use here. (Plus, when I bought it, the book was under $3, so I figured why not?)
