Centilog breakout module
Assembled DWM3000 breakout with a breadboard-friendly 1×8 pinout, for fast integration with any MCU.
Standalone breakout exposing the Qorvo DWM3000 module on a single 1×8 row (2.54mm pitch) along the bottom edge — plugs straight into a breadboard with no short circuits. The UWB antenna stays at the top, away from the breadboard (RF keep-out preserved). Careful decoupling (3× 100nF + 1× 10µF bulk), RSTn pull-up, IRQ pull-down. Two diagnostic LEDs included.
