How to Use a UWB Tag to Read Its Position
A UWB tag works out its own position. The anchors do not compute a coordinate and hand it down to the tag, and once that direction is clear, so is the question of where to go looking for the numbers. On the developer tag in the GrowSpace Creator Kit (Q1), they come out over serial. […]
How Many UWB Anchors Do You Need? (2D vs 3D)
You mapped the space, picked your tags, and now one number is holding up the whole order: how many anchors do you actually buy. Buy too few and the position never resolves. Buy too many and the extra hardware just sits in a drawer gathering dust. This guide hands you the number, the reason behind […]
Build Your Own UWB Setup, or Buy a Kit? An Honest Guide
You want centimeter-level indoor position, and you’ve hit the fork every maker hits. Buy a finished UWB dev kit, or wire up a few cheap modules and build your own? The parts for a DIY rig cost almost nothing, and that single fact, more than any spec sheet or shootout you’ll read on a forum, […]
UWB Indoor Positioning: A Beginner’s Guide
Indoors, GPS quits. Walk into a warehouse and your phone’s blue dot drifts through walls, lands two aisles over, then gives up. The signal from satellites cannot punch through a steel roof and metal racking, so anything that needs to know where it sits, down to the centimeter, hits a wall the moment it steps […]
UWB Arduino Positioning: How to Get Real X,Y Coordinates
Most “uwb arduino” tutorials stop at distance. You wire up two off-the-shelf UWB modules, run an open-source ranging library, and the serial monitor prints a number in meters. Then you try to turn three of those distances into an actual point on the floor, and the whole thing falls apart. That gap is the reason […]
Creator Kit vs Creator Expansion Kit: Which Q1 UWB Kit Is Right for Your Project?
Hello! This is Freegrow. GrowSpace’s UWB kit line comes in two configurations built around the same 10–30 cm accuracy, but sized for different stages of a project: the Creator Kit and the Creator Expansion Kit. Both kits use the same UWB anchor-based positioning technology. The difference is in what’s in the box, how the system […]
UWB RTLS Experiment with Creator Kit: Pedestrian Detection and Danger Zone Alerts
Hello, this is Freegrow 👋 In the last story, we shared how a student project team first tried to use a DIY DWM1000 module. That attempt failed, and finally, they chose the UWB Creator Kit. With Q1, the students felt, “Now we can do this project in the right way.” Then they started their real […]
UWB RTLS Creator Kit : Why We Chose It and First Results
Hello, this is Freegrow. In the last post, we shared a case where a university student team tried to use the Crowtail DWM1000 module and a DIY soldered DWM1000 module. But they faced many problems. The main issues were unstable communication and hardware limits. The biggest lesson was simple:“To succeed, you must choose a verified […]
UWB RTLS Creator Kit Used by University Students: Pedestrian Tracking and Safety Test Case
Hello, this is Freegrow. Today, we want to share an interesting case where real users tested our UWB Creator Kit (Q1). The main actors of this test are university students from the Department of Electronic Engineering. They worked on a project called “Pedestrian Tracking and Danger Zone Alert” and used Freegrow’s RTLS technology. Let’s see […]
