The SparkFun NEO-M8U GPS Breakout is a high quality, GPS board with equally impressive configuration options. The NEO-M8U takes advantage of u-blox's Untethered Dead Reckoning (UDR) technology. The module provides continuous navigation without needing to make any electrical connection to a vehicle, thus reducing cost of installation for after-market dead reckoning applications.

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

The NEO-M8U module is a 72-channel u-blox M8 engine GNSS receiver, meaning it can receive signals from the GPS, GLONASS, Galileo, and BeiDou constellations with ~2.5 meter accuracy. The module supports concurrent reception of three GNSS systems. The combination of GNSS and integrated 3D sensor measurements on the NEO-M8U provide accurate, real-time positioning rates of up to 30Hz.

Compared to other GPS modules, this breakout maximizes position accuracy in dense cities or covered areas. Even under poor signal conditions, continuous positioning is provided in urban environments and is also available during complete signal loss (e.g. short tunnels and parking garages). With UDR, position begins as soon as power is applied to the board even before the first GNSS fix is available! Lock time is further reduced with on-board rechargeable battery; you'll have backup power enabling the GPS to get a hot lock within seconds!

Additionally, this u-blox receiver supports I2C (u-blox calls this Display Data Channel) which made it perfect for the Qwiic compatibility so we don't have to use up our precious UART ports. Utilizing our handy Qwiic system, no soldering is required to connect it to the rest of your system. However, we still have broken out 0.1"-spaced pins in case you prefer to use a breadboard.

U-blox based GPS products are configurable using the popular, but dense, windows program called u-center. Plenty of different functions can be configured on the NEO-M8U: baud rates, update rates, geofencing, spoofing detection, external interrupts, SBAS/D-GPS, etc. All of this can be done within the SparkFun Arduino Library!

The SparkFun NEO-M8U GPS Breakout is also equipped with an on-board rechargeable battery that provides power to the RTC on the NEO-M8U. This reduces the time-to-first fix from a cold start (~26s) to a hot start (~1.5s). The battery will maintain RTC and GNSS orbit data without being connected to power for plenty of time.

⭐️ A Beautifully Written Story That Stays With You ⭐️
Format: Paperback, Format: Paperback
Theo of Golden by Allen Levi is one of those rare books that quietly settles into your heart and lingers long after the final page. The writing is intelligent, thoughtful, and beautifully crafted, with storytelling that feels both timeless and deeply human. The characters are wonderfully developed and feel incredibly real, but Theo himself is unforgettable. I found myself learning so much from him along the way about life, people, kindness, and perspective. Allen Levi has a gift for creating a world that feels warm, meaningful, and genuine. This was a truly lovely read, full of wisdom, heart, and beautiful prose. An easy five stars for me. 📚✨

A story of art, music and writing
Format: Kindle
Like the face of heaven. That’s how I see Theo, and I hope this will be a movie. “Theo of Golden” is the debut novel by Allen Levi. He was writing as a personal challenge and just doing some scenes. He began writing in 2019-2020. He had been a songwriter and lawyer. He has no connection to Portugal, which is mentioned in the book quite a bit and led me to try Port wine. This book will lead me to do a lot of things. Theo is a supremely interesting man! More on that other familiar interesting man in a later post. The book will make you want to look at the faces of people. Use a gaze that calms and loves. Be kind and generous. Greet people. Be less fearful and exchange stories. Be attentive. Love people up close. Invest in the art of living. Be beautiful, useful and pleasurable. All which I should be doing, but will now do for Lent. Theo listened with genuine interest, adoringly, encouraging and with gratitude. Newborns look for their mother’s face, a particular gaze that calms, loves and welcomes them. Someone they recognize, run to greet and someone to bond with. Levi signs the books “With thanks for the Theo in you.” He greets kids at a high school three days a week. He reads to second graders. He doesn’t mind being around people not like him. The coffee shop setting is a real place in Columbus, Ga. It’s called Fountain City Coffee. In picking bestowals of the sketches there, Theo looked for someone lost, weary, worried or troubled that the gift would encourage or help. I got to hear him in a Zoom. A group of women from Vermont who lost their daughters came to Georgia on a pilgrimage. He was a steward of clean rivers and water and said the river still flows after death. He went through a “walking season” in losing his daughter. In a book about knowing a person, it is mentioned that a bench is a good way to do this. 7 p.m. was Theo’s meeting time with the strangers for bestowals and ended up being the time of the funeral. He also mentioned “Think Little” by Wendell Berry. Do so and if everyone does, it spreads. Levi was born in 1956. His dad is 98. His mother passed and he lost his brother, whom he called a clone of Theo, at 55. His dad was a forester, explaining his interest in nature. Springtime is an end with a future, said Theo. One character named Tony runs the Verbivore book store and has the Penny Loafers out there because they haven’t spent a penny and they majored in loafing. Theo and Tony end up having Port together and he told Theo is Viet Nam stories. The Penny Loafers were better than a room full of Senators. They lie. Tony ends up being more of a believer of Jesus at the end because he wasn’t before Theo. James Ponder has no degrees hanging in his office. Note the “ponder” mentions throughout. He is a dispenser of advice, secret keeper and agent of calm. Secretary Mrs. Gidley was suspicious of Theo at first but comes around. Ponder was Theo’s landlord and mentioned the 18-inch railing and three flights of stairs before the 86 year old decided to live there. Kendrick reminds me of the custodian who won “America’s Got Talent,” who has an ill daughter Lamisha, who wants to be a physical therapist or artist in the end. Her education will be paid for by Theo as were some of her medical bills. Maria Menendez is the daughter of the “little man” who killed Theo’s wife and daughter in an accident. Maria had cancer. I don’t want to give away too much, but Theo decided to love Asher, the sketch artist, with two hearts. And there is much more to that. Simone wears a wardrobe that honors music on stage and guests who come to listen did the same. Cello intricacies became fascinating to me and I looked up some of the music mentioned. His bow was a gift from Theo. He played Fado for Theo at his concert. It ended up being a requiem with three characters, Kendrick and Basil, the busker. Simone’s parents were there and I wasn’t clear if Theo sprang for their trip. At the end, Basil studies to get a doctorate in American literature. Katherine is the reporter who respects Theo’s wishes while many people she interviews are praise seekers and applause junkies. He was a friend, not a headline. Ellen rides a bike and I’ll just call her different. He gave her a foldable handsaw, cordless sander, drill and wood burner to make feather boxes. I have made one because of this book. She had $1,600 to her name from selling them, but gave the money to the cello fund after she and Simone were assaulted and the perpetrator was never caught. Cleave is the poisonous guy—like a snake, hemlock, black widow or “words with no wisdom guy.” All but Cleve show community in sitting on the same row or pew. They all have sparks of hope. I loved this line: We walk all roads, long and winding. Road to ruin. Easy Street. Road less traveled. I’m so mad that my notes from Chapter 10-28 somehow disappeared. I may reread. This post would be longer. I probably have a dozen favorite books and just added this one.

Recognizing the Hearts that Burn Within Us
Format: Paperback
Yes, Theo of Golden does, at times, border on the melodramatic and the sentimental. It can be repetitive. It can take an awfully long time to make its point. And yet, the novel speaks very significantly of the need for love, compassion, generosity and forgiveness---in a world that is not always kind, in a world where many of us carry secret burdens---where sadness (mixed with intermittent joy) might be viewed as a universal human affliction. Theo of Golden is, overall, a book of glad tidings. An end with a future. Thoughtfully, warmly and intelligently written. A novel that often addresses the beauty of Art, most notably painting and music. A novel in which I learned what a fado is. In fact, I learned a lot from this novel. Unlike some readers, I did not see the book as misogynistic or xenophobic. I didn't necessarily see it as "Christian fiction"---unless you mean doing good, striving for strength of spirit and understanding the connection between "the ultimate and the proximate, the wide grace and the narrow way." Finally, I don't view the novel's conclusion as disappointing, but simply as falling action and resolution. It is, after all, a very traditionally structured work. Kudos to the author Allen Levi for having written an initially self-published book that was later picked up by a major publishing house. That is, indeed, a rarity.
