Tag PRO
from $60
Tag PRO is a compact IP67 device, which is capable of working as a UWB-BLE RTLS tag or anchor. The device includes Bosch 6-axis IMU, barometer, programmable NFC module, USB power supply and optional ESP8266 Wi-Fi module with UFL antenna.
The default usage scenarios for Tag PRO include tracking equipment and vehicles in various industrial environments, such as factories, warehouses and non-ATEX mining areas. For example:
- 2D-3D position tracking or 1D ranging for overhead cranes and rail-based equipment in factories.
- Vehicle tracking in underground mines or warehouses (e.g. forklifts).
- Theft prevention and inventory management based on 2D-3D UWB RTLS or BLE Zoning for equipment.
- Collision Avoidance and Proximity Detection Subsystem with Android HMI for vehicles.
- Personnel tracking scenarios where RTLS tags should be attached to helmets or other PPE items.

PCB Components
- BLE chipset and antenna: Nordic nRF52840, SMD chip antenna
- UWB chipset and antenna: Qorvo/Decawave DW1000, SMD chip antenna
- 6-axis IMU (accelerometer, gyroscope): Bosch BMI270
- Barometer: Bosch BMP390
- Wi-Fi module and antenna (optional): ESP8266 with UFL connector for Taoglas 2.4 GHz antenna
- Two options for power supply:
- Direct USB power supply – no accumulator is needed
- Rechargeable 3.7V Li-Po accumulator (recharging via USB)
- Connectors:
- Protected Micro-USB connector
- Connector for NFC antenna
- Internal UART connector for sensors or ESP8266 Wi-Fi module
- Internal connector for Li-Po / Li-Ion accumulator
RTLS Technologies
- UWB for 1D-3D RTLS scenarios based on TWR and our custom algorithm with 5-10 cm accuracy.
- Tunnel UWB/BLE RTLS algorithms, which were developed specifically for underground mines.
- Custom UWB TDoA algorithm for highly scalable and low-power 2D RTLS scenarios, which need 50-60 cm accuracy for RTLS.
- BLE zoning based on RSSI and Kalman filtering - suitable for room-level tracking scenarios.
- Height tracking based on the embedded barometer - suitable for floor/level detection with less RTLS anchors.
- Sensor telemetry for RTLS tags over UWB or BLE payloads - accelerometer, gyroscope, temperature.
Locator LITE
Locator LITE is a modification of Tag PRO with ESP8266 Wi-Fi module on board and the extended firmware for RTLS anchor features. This is a lower cost alternative to Locator PRO RTLS anchor, when you need a compact UWB TWR anchor with Wi-Fi connectivity and USB power supply.
