An open port of Qorvo/Decawave's DWM3000 driver and ranging examples (the dwt_uwb_driver API) to the DWS3000 Arduino shield, runnable under Zephyr. The practical glue for bringing up a DW3000 board, configuring its 802.15.4z PHY parameters (channel, preamble, PRF, STS mode), and running two-way-ranging exchanges you can log — the dev-board path for capturing/characterising ranging behaviour. A development driver, not an attack tool.
