ZDNET’s key takeaways
- Challenger UWB is powered by the Raspberry Pi Pico 2040 chip.
- It permits for monitoring accuracy all the way down to 10cm.
- Low energy consumption makes it good for cellular functions.
Asset monitoring is a giant factor, whether or not that be automobiles, instruments, and even individuals transferring a few web site, and whereas there are a selection of off-the-shelf options obtainable — the Apple AirTag being one which’s very generally used — some wish to construct their very own techniques.
And you may. You simply want some {hardware}, some software program know-how, and also you’re able to go. A little bit of equipment I have been experimenting with just lately is the iLabs Challenger RP2040 UWB.
Additionally: The best Raspberry Pi alternatives of 2025: Expert recommended
Because the identify suggests, this board is an Adafruit Feather format microcontroller board outfitted with a DWM3000 ultra-wideband (UWB) module and powered by the Raspberry Pi Pico 2040 chip with 8MB of flash storage and 264KB of RAM.
Nice for small-scale techniques
These boards aren’t low-cost at about $65 to $75 each, however they’re a fantastic possibility for small-scale techniques or one thing bespoke that might in any other case price some huge cash (or simply not be doable).

The DWM3000 permits for object monitoring all the way down to a precision of 10cm/4 inches. The module is suitable with Apple’s U1 and U2 first- and second-generation ultra-wideband chips, and in addition FiRa-compatible gadgets.
Additionally: A wireless heart rate monitor powered by Raspberry Pi and Wi-Fi – how it works
The board is constructed to be cellular, able to being powered by a LiPo battery with a JST connector or USB-C. Energy consumption is tremendous low at solely 75mA when lively and a minuscule 1.5 μA throughout sleep mode. This implies you possibly can have this working off a small battery for an prolonged time frame.
The board is a wonderful little bit of equipment. Nevertheless it’s only a board.
It is advisable to add the smarts
Which means realizing easy methods to deal with Arduino code. Numerous the code you want is on the market from iLabs, and if Arduino is all new to you, there are some great primers to get you began.

For those who’re used to getting elbows-deep into Raspberry Pi and Arduino initiatives, it will all be a doddle for you. For those who’re a beginner and also you’re inquisitive about studying, this can be a nice challenge to sink your enamel into.
However if you happen to’re not inquisitive about coding and messing about with batteries and potential soldering, you are finest sticking to off-the-shelf options — both shopper finder tags for iOS or Android (or both) the place the price is within the tens or a whole lot of {dollars}, or go full-on pro and spend a number of hundred to a number of thousand {dollars}.
