Open-source firmware

Arduino / ESP32 downloads

DS-TWR sketches for the DWM3000 module. Each archive contains the ready-to-open Arduino sketch folder. MIT license.

Anchor firmware — ESP32-DevKitC (.zip) — DS-TWR responder, set ANCHOR_ID (1/2/3).
Anchor firmware — ESP32-S3 (.zip) — ESP32-S3 variant.
Mobile tag firmware — ESP32 (.zip) — set WIFI_SSID / WIFI_PASSWORD / RELAY_IP before flashing.
Combined TWR demo (.zip) — anchor + tag in a single sketch (educational).

Required library. Install the Makerfabs ESP32 UWB DW3000 library in the Arduino IDE (sketches do #include "dw3000.h"). The Node.js UDP→SSE relay is included in the repo.
