UWB module empowers high-precision ranging and positioning landing

2026-08-31/ By Admin

High‑precision ranging and positioning are foundational for collision avoidance, personnel monitoring and automated guidance across industrial automation, warehouse logistics, robot navigation and smart security.

Traditional Bluetooth RSSI and Wi‑Fi fingerprint positioning suffer heavily from signal fluctuation and multipath interference, typically delivering meter‑level accuracy that fails strict centimeter‑error requirements. While conventional UWB modules offer good precision, their effective range is often limited to several tens of meters, insufficient for large workshops, warehouses and open‑air outdoor sites.

How to combine centimeter‑grade accuracy with extended operating range? The SKU622 UWB ranging module addresses this challenge. Powered by Qorvo DW3210 UWB transceiver and Nordic nRF52833 BLE 5.1 MCU, it achieves ±10 cm static ranging accuracy and over 200 m line‑of‑sight distance. Native support for TWR two‑way ranging and TDOA positioning makes it a flexible hardware core for high‑precision ranging, 1D positioning and wireless data transfer.

Key Pain Points of Legacy Ranging & Positioning Solutions

• Accuracy limitations: Bluetooth and Wi‑Fi positioning are vulnerable to environmental noise, producing meter‑scale errors unsuitable for collision prevention or precision automated guidance.
• Insufficient coverage: Standard UWB modules often fall short of 100 m real‑world effective range, creating coverage gaps in large warehouses, ports and mining yards.
• High development barrier: In‑house UWB development requires RF tuning, antenna matching and positioning algorithm implementation. These steps extend project timelines and raise technical risks for engineering teams.

SKU622 mitigates these pain points through hardware integration, RF optimization and complete developer resources.

Core Product Advantages

Centimeter‑level static ranging for demanding positioning tasks

Compliant with IEEE 802.15.4‑2022 UWB standard, the module leverages nanosecond narrow pulses for superior time resolution. Under typical operating conditions, static ranging reaches ±10 cm, while dynamic ranging maintains sub‑meter performance. Well‑suited for collision‑avoidance alerts, automated vehicle guidance and parking‑lot asset positioning.

200 m+ line‑of‑sight ranging for wide‑area deployments

Integrated PA and LNA boost transmit power and receiver sensitivity. In clear line‑of‑sight conditions, maximum ranging exceeds 200 m — a major upgrade over conventional UWB modules limited to tens of meters. Large‑scale sites including warehouses, open mines and port terminals require fewer base stations to achieve full‑area coverage, lowering total system cost.

On‑board BLE 5.1 MCU enables secondary development & streamlined debugging

The Nordic nRF52833 host supports BLE 5.1 for wireless configuration and data passthrough. Multiple GPIOs can be remapped as UART, SPI, I2C or PWM interfaces to connect external sensors and actuators.

Designs can run application logic directly on‑module without an external MCU, reducing BOM cost. Bluetooth‑enabled over‑the‑air firmware updates and parameter tuning accelerate on‑site debugging.

Compact form factor with dual‑antenna options for easy product integration

Dimensions: 22.5 mm × 19 mm × 2.5 mm. Three‑sided half‑hole pads support standard SMT assembly. Two variants are available: onboard PCB antenna and IPEX‑III / UFL external antenna. The external‑antenna version works with high‑gain antennas to further extend ranging performance, adapting to diverse mechanical constraints of end‑products.

Industrial wide‑temperature range & low‑power operation

Rated for 3.3 V nominal supply, operating temperature from ‑40 °C to 85 °C, stable for both factory indoor and harsh outdoor installations. Built‑in power‑management functions make it suitable for battery‑powered portable tags.
