LE-UWB™ Evaluation Kits
Benchmark LE-UWB™ wireless performance against your application - data rate, latency, power, range with hardware that ships ready to run.
Development Hardware
SPARK evaluation kits give engineering teams a complete platform to test LE-UWB™ performance, prototype real applications, and validate design assumptions before silicon integration.
