It enables centimeter-accurate indoor positioning and distance measurement using UWB technology, while leveraging the ESP32's WiFi and Bluetooth for data relay and cloud connectivity. Ultra-wideband (UWB) is a short-range wireless communication protocol that operates through radio waves, enabling secure reliable ranging and precision sensing. The DW3000 chip achieves 10cm positioning accuracy, making it suitable for real-time location systems (RTLS), asset tracking, and presence detection. ## Key Advantages Over DW1000 The DW3000 represents a significant upgrade over the previous generation DW1000/DWM1000: - **Apple U1 Interoperability** -- Compatible with Apple's U1 chip ecosystem for integration with iPhones and AirTags - **FiRa Compliance** -- Fully aligned with FiRa PHY, MAC, and certification development for cross-vendor interoperability - **Lower Power Consumption** -- Approximately 1/3 the power draw of the DWM1000 - **Dual Channel Support** -- Supports UWB Channel 5 (6.5 GHz) and Channel 9 (8 GHz); the DWM1000 only supports Channel 5 ## Hardware Variants The board is available in two ESP32 module variants: | Variant | Module | PSRAM | Price | |---------|--------|-------|-------| | WROOM | ESP32-WROOM-32 | None | $43.80 | | WROVER | ESP32-WROVER | 8MB | $45.80 | Both variants share the same PCB layout and DW3000 UWB transceiver. ## Pin Mapping (ESP32 to DW3000) The DW3000 communicates with the ESP32 over SPI: | ESP32 GPIO | Function | Direction | |-----------|----------|-----------| | GPIO18 | SPI SCK | Output | | GPIO19 | SPI MISO | Input | | GPIO23 | SPI MOSI | Output | | GPIO4 | SPI SS (Chip Select) | Output | | GPIO27 | DW3000 Reset | Output | | GPIO34 | DW3000 IRQ | Input | I2C pins (GPIO4 SDA, GPIO5 SCL) are available for connecting an optional SSD1306 OLED display. ## Getting Started 1. Install the Arduino IDE or PlatformIO 2. Clone the [Makerfabs ESP32 UWB DW3000 library](https://github.com/Makerfabs/Makerfabs-ESP32-UWB-DW3000) into your Arduino libraries folder 3. Flash the `range_tx` example to one board (tag) and `range_rx` to another (anchor) 4. Open Serial Monitor at 115200 baud to see distance measurements The library includes Two-Way Ranging (TWR) examples for basic distance measurement between two boards. ## ESPHome Integration A community-maintained [ESPHome UWB component](https://github.com/realzoulou/esphome-uwb-dw3000) enables direct integration with Home Assistant. It supports multi-anchor setups (up to 8 anchors, 32 tags) for real-time indoor positioning with automatic location calculation and reporting to Home Assistant. ## Applications - **Indoor Asset Tracking** -- Track equipment, inventory, or personnel in warehouses, hospitals, and factories with centimeter accuracy - **Room-Level Presence Detection** -- Determine which room a person or device is in for smart home automation - **Robotics Navigation** -- Provide precise position feedback for autonomous robots and drones - **Secure Ranging** -- IEEE 802.15.4z provides built-in security against relay attacks, useful for access control - **Sports & Motion Analysis** -- Track athlete or object movement with high temporal and spatial resolution ## Resources - [Makerfabs Wiki](https://wiki.makerfabs.com/ESP32_DW3000_UWB.html) -- Setup guides and technical documentation - [GitHub Repository](https://github.com/Makerfabs/Makerfabs-ESP32-UWB-DW3000) -- Arduino library, examples, and hardware files - [DW3000 Datasheet (Qorvo)](https://www.qorvo.com/products/d/da008142) -- Full transceiver specifications - [Hardware Schematics](https://github.com/Makerfabs/Makerfabs-ESP32-UWB-DW3000/tree/main/hardware) -- Eagle schematic and board files (open source) ## Where to Buy - [Makerfabs](https://openhardware.directory/r?to=https%3A%2F%2Fwww.makerfabs.com%2Fesp32-uwb-dw3000.html&ref=openhardware.directory&product=makerfabs-esp32-uwb-dw3000&source=md-export) — $43.80 - [Tindie](https://openhardware.directory/r?to=https%3A%2F%2Fwww.tindie.com%2Fproducts%2Fmakerfabs%2Fesp32-uwb-dw3000ultra-wideband%2F&ref=openhardware.directory&product=makerfabs-esp32-uwb-dw3000&source=md-export) — $43.80 ## Resources - [product](https://openhardware.directory/r?to=https%3A%2F%2Fwww.makerfabs.com%2Fesp32-uwb-dw3000.html&ref=openhardware.directory&product=makerfabs-esp32-uwb-dw3000&source=md-export) - [github](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2FMakerfabs%2FMakerfabs-ESP32-UWB-DW3000&ref=openhardware.directory&product=makerfabs-esp32-uwb-dw3000&source=md-export) - [wiki](https://openhardware.directory/r?to=https%3A%2F%2Fwiki.makerfabs.com%2FESP32_DW3000_UWB.html&ref=openhardware.directory&product=makerfabs-esp32-uwb-dw3000&source=md-export) - [datasheet](https://openhardware.directory/r?to=https%3A%2F%2Fwww.qorvo.com%2Fproducts%2Fd%2Fda008142&ref=openhardware.directory&product=makerfabs-esp32-uwb-dw3000&source=md-export) - [schematics](https://openhardware.directory/r?to=https%3A%2F%2Fgithub.com%2FMakerfabs%2FMakerfabs-ESP32-UWB-DW3000%2Ftree%2Fmain%2Fhardware&ref=openhardware.directory&product=makerfabs-esp32-uwb-dw3000&source=md-export) ## Tags `esp32`, `uwb`, `dw3000`, `indoor-positioning`, `ranging`, `rtls`, `fira`, `apple-u1`, `ultra-wideband`, `iot` ## Images ![Makerfabs ESP32 UWB DW3000](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-dw3000/5c46312aefef.jpg) ![Makerfabs ESP32 UWB DW3000](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-dw3000/a03bd6b4fcbc.jpg) ![Makerfabs ESP32 UWB DW3000](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-dw3000/32e3605a1ebc.jpg) ![Makerfabs ESP32 UWB DW3000](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-dw3000/8ef807b057c8.jpg) ![Makerfabs ESP32 UWB DW3000](https://nbg1.your-objectstorage.com/openhardware-directory/entities/makerfabs-esp32-uwb-dw3000/12550b971ec5.jpg) --- [View full device page](https://openhardware.directory/devices/makerfabs-esp32-uwb-dw3000)
