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

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.
I think you can also post this question to Dronebot workshop. Many drone enthusiasts are there.
ahsrab.rifat Hi Jordan! It sounds like you're facing some interesting challenges with your drone project. Voltage dips can definitely cause those erratic readings, so ensuring a stable power supply would be key. Have you considered isolating the power for the UWB module? Additionally, for antenna placement, maintaining distance from noisy components is crucial. You might also explore solutions like Block Blast. , which could offer some insights into signal integrity. Best of luck with your project!
