It pairs an ESP32-WROVER module with a Decawave DWM1000 ultra-wideband transceiver to enable secure, reliable ranging and precision sensing with centimeter-level accuracy at distances up to 200 meters (line of sight). The board is designed for indoor positioning systems (RTLS), asset tracking, and distance measurement applications. Using UWB channels 2 and 5, the DWM1000 module provides IEEE 802.15.4-2011 compliant communication with time-of-flight ranging that is resistant to multipath interference — a significant advantage over WiFi or Bluetooth-based positioning approaches. The onboard OLED display shows real-time ranging data without requiring an external monitor. With built-in WiFi and Bluetooth 4.2 from the ESP32-WROVER, the board can relay positioning data over the network to a central server or dashboard. The integrated LiPo battery connector and charger circuit enable portable operation as a mobile tag or anchor node. Multiple boards can work together — configured as anchors and tags — to create a complete indoor positioning system using the provided Arduino example code for both indoor and outdoor positioning scenarios. ## Where to Buy - [Tindie](https://openhardware.directory/r?to=https%3A%2F%2Fwww.tindie.com%2Fproducts%2Fmakerfabs%2Fesp32-uwb-pro-with-display%2F&ref=openhardware.directory&product=makerfabs-esp32-uwb-pro-with-display&source=md-export) — $54.80 - [Makerfabs](https://openhardware.directory/r?to=https%3A%2F%2Fwww.makerfabs.com%2Fesp32-uwb-pro-with-display.html&ref=openhardware.directory&product=makerfabs-esp32-uwb-pro-with-display&source=md-export) — $54.80 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.makerfabs.com%2Fesp32-uwb-pro-with-display.html&ref=openhardware.directory&product=makerfabs-esp32-uwb-pro-with-display&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2FMakerfabs%2FMakerfabs-ESP32-UWB&ref=openhardware.directory&product=makerfabs-esp32-uwb-pro-with-display&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwiki.makerfabs.com%2FESP32_UWB_Pro_with_Display.html&ref=openhardware.directory&product=makerfabs-esp32-uwb-pro-with-display&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fwww.espressif.com%2Fsites%2Fdefault%2Ffiles%2Fdocumentation%2Fesp32-wrover_datasheet_en.pdf&ref=openhardware.directory&product=makerfabs-esp32-uwb-pro-with-display&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2FMakerfabs%2FMakerfabs-ESP32-UWB%2Fblob%2Fmain%2Fhardware%2FESP32%2520UWB%2520Pro%2520with%2520Display%2520v1.2.sch&ref=openhardware.directory&product=makerfabs-esp32-uwb-pro-with-display&source=md-export) ## Tags `esp32`, `uwb`, `ultra-wideband`, `indoor-positioning`, `dw1000`, `dwm1000`, `ranging`, `rtls`, `oled`, `makerfabs` ## Images ![Makerfabs ESP32 UWB Pro with Display](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-pro-with-display/74597c56e127.jpg) ![Makerfabs ESP32 UWB Pro with Display](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-pro-with-display/759b25f5d296.jpg) ![Makerfabs ESP32 UWB Pro with Display](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-pro-with-display/81a6cc078e9c.jpg) ![Makerfabs ESP32 UWB Pro with Display](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-pro-with-display/3375e65472e8.jpg) ![Makerfabs ESP32 UWB Pro with Display](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-pro-with-display/49fa800772ca.jpg) ![Makerfabs ESP32 UWB Pro with Display](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-pro-with-display/d4a1b6f0913e.jpg) > **Battery Powered:** Li-Po --- [View full device page](https://openhardware.directory/devices/makerfabs-esp32-uwb-pro-with-display)
