UDB‑IoT – Ubiquiti Device Bridge IoT
Description
Description
The UDB‑IoT from Ubiquiti is a compact and reliable wireless device bridge designed specifically to bring wired IoT devices onto an existing UniFi WiFi network without running Ethernet cabling. Ideal for space‑restricted or retrofit installations, this ultra‑small unit enables seamless network connectivity for sensors, controllers, printers and industrial devices.
Using UniFi WiFi Auto‑Link, the UDB‑IoT adopts quickly into UniFi environments, allowing fast deployment and centralised management. It operates on 2.4 GHz WiFi 4 (802.11n) with up to 300 Mbps throughput and provides a single 10/100 RJ45 Ethernet port for wired device connection.
Key Features
- Ultra‑compact wireless bridge for IoT and Ethernet‑only devices
- WiFi 4 (802.11n) connectivity with 2×2 MIMO
- 300 Mbps maximum wireless data rate
- USB‑C or 4‑pin DC power (9–30V DC)
- Wall or DIN‑rail mounting included
- Internal 4 dBi antenna plus external antenna support
- Low power consumption of just 2.3 W
Ideal for
The UDB‑IoT is ideal for system integrators, installers and businesses needing to connect wired IoT devices in warehouses, retail spaces, automation cabinets, smart buildings or temporary deployments where Ethernet cabling is impractical.

FAQs
Does the UDB‑IoT act as a long‑range wireless bridge?
No. The UDB‑IoT is designed to connect wired devices to an existing UniFi WiFi network rather than creating a long‑distance point‑to‑point link.
How is the UDB‑IoT powered?
It can be powered via USB Type‑C (5V DC) or through the 4‑pin DC input supporting 9–30V DC.
