Discovery station

The minimum to discover UWB on a breadboard and write your own firmware.

Centilog breakout module, the starting point to experiment with UWB — **Starting point** One Centilog module + one ESP32 on a breadboard: enough to measure your first UWB distance via DS-TWR.

An educational setup to get going: a Centilog module, an ESP32 ready to program, a breadboard and cables. Ideal for schools, student projects and makers discovering UWB. All the code and documentation are public — you learn by reproducing, nothing is sold here.

Hardware to gather to get started

1× Centilog breakout module (build it)
1× ESP32-DevKitC (38 pins)
1× 400-point breadboard
1× set of M-M Dupont cables, 20 cm
1× USB-A to Micro-USB cable
DS-TWR firmware, Arduino examples, wiring diagrams and 3D viewer — Resources page

What you'll learn

Wire up SPI between an ESP32 and the DWM3000
Implement the DS-TWR protocol (POLL → RESPONSE → FINAL → RESULT)
Calibrate the antenna delay to reach centimetre accuracy
Stream measurements over WiFi/UDP and visualize in 3D in a browser
Scale to a 3 anchor + 1 tag system (by adding 3 more Centilog modules)
