Trouble integrating the ESP‑WROOM‑32 + UWB module in my drone project

Hey everyone on the DFRobot forum,

I’m working on a drone tracking system and using an ESP32 board together with a UWB chip (the DW1000) for precise positioning. I found a good article and library about this setup. I connected the ESP32 to the DW1000 via SPI, but the range readings are unstable, sometimes out by several meters. The power rail is shared between the ESP32, the UWB chip, and the motor controller, and I suspect voltage dips when the motors spin. Also, the UWB antenna is right next to large copper motor traces, maybe layout or noise is causing signal errors.

Has anyone used ESP32 + DW1000 in drone or mobile setups? I’d love your advice on:

Power/ground layout for clean SPI/UWB signals

How to physically place the UWB antenna on a drone without interference

Any library tweaks or calibration steps to improve accuracy

Thanks a ton.
