LBUA2ZZ2DK-882 Übersicht
An Ultra-Wideband module is a short-range, high-precision RF transceiver that transmits narrow pulses across a wide spectrum, enabling centimeter-level ranging and secure fine-ranging. Within the wireless connectivity hierarchy, it sits alongside BLE, Wi-Fi and GNSS as a radio module, and combo modules such as this integrate both the UWB PHY and a companion short-range radio plus host MCU on a single certified, pre-tested footprint, dramatically reducing RF design effort compared with discrete chipsets.
Key features include the NXP Trimension SR040 UWB chipset for IEEE 802.15.4z-class fine ranging, the NXP QN9090 Bluetooth LE and ARM Cortex-M4-based MCU for application processing, and an integrated antenna with matching components and crystals already on-board. This all-in-one integration means developers avoid antenna tuning and RF layout iterations, achieving regulatory radio certification with a single module.
Technically, the module combines two independent radio chains: the SR040 handles UWB channel access in the 6.25-8.25 GHz band used for secure distance bounding, while the QN9090 provides Bluetooth v5.0 LE connectivity for provisioning, data backhaul and device-to-device communication. Low-power design supports coin-cell battery operation, which is central to the tag and tracker use case.
Typical applications include UWB tags and trackers, smart-door locks and access control, indoor positioning and asset tracking in factories and hospitals, and general IoT devices that need precise ranging plus a BLE control link.
A key design consideration is power budgeting: UWB ranging sessions dominate energy consumption, so duty-cycle the UWB radio and rely on BLE for standby communication to maximize coin-cell life.

Typische Anwendungen
LBUA2ZZ2DK-882 ist geeignet für 6 Anwendungs: UWB Tags and Trackers, Smart Door Locks and Access Control, Indoor Asset Tracking, General IoT Devices with Precise Ranging, Secure Fine Ranging / Keyless Entry, Wireless Sensor Nodes and Mesh Edge Devices.
UWB Tags and Trackers
Murata explicitly positions the Type 2DK as ideally suited for coin-cell powered UWB tags and trackers. The module's NXP Trimension SR040 chipset delivers fine ranging in the 6.25-8.25 GHz band for centimeter-class distance bounding, while the QN9090's Bluetooth v5.0 LE handles low-power advertising, provisioning and data backhaul. In a tag, the BLE radio remains the standby communication channel and UWB sessions are triggered on demand, preserving battery life. The integrated chip antenna and 19.6 x 18.2 x 2.3 mm LGA-127 footprint allow a compact tag PCB with no RF tuning work. The key performance consideration is duty-cycling UWB ranging, which dominates energy consumption versus BLE standby.
Empfohlen
Smart Door Locks and Access Control
UWB-based access systems use secure fine ranging to unlock doors only when an authorized device is deliberately close, preventing relay attacks that defeat BLE-only locks. The LBUA2ZZ2DK-882 fits this role because the SR040 provides distance-bounded measurements in the 6.25-8.25 GHz UWB band, while the QN9090 maintains a Bluetooth v5.0 LE link for key exchange, mobile-app provisioning and cloud connectivity. The integrated antenna and pre-certified radio shorten product development since no RF certification iteration is needed. Designers should locate the module so the on-board antenna faces the approach direction and verify ranging accuracy against metal door-frame reflections during system integration.
Empfohlen
Indoor Asset Tracking
In factories, warehouses and hospitals, UWB delivers room-level and shelf-level location accuracy that BLE beacons and Wi-Fi cannot match. The LBUA2ZZ2DK-882 acts as a tag-side or anchor-side radio: its SR040 chipset exchanges ranging messages in the 6.25-8.25 GHz band with UWB anchors, and the QN9090's ARM-based MCU runs tag firmware and manages the 2.4 GHz BLE fallback link. Low power consumption supports coin-cell or small Li-MnO2 batteries on hundreds of disposable or semi-permanent asset tags. Because the module is radio certified, large rollouts avoid per-device regulatory testing. Trade-off: anchor infrastructure cost is significant compared with passive RFID.
Empfohlen
General IoT Devices with Precise Ranging
Beyond dedicated tags, Murata markets Type 2DK for general IoT devices that benefit from accurate distance measurement: smart speakers that wake for the nearest user, robots that dock by range, and child/elder-care proximity monitors. The module's two-chip architecture is advantageous because the QN9090 MCU has headroom to run device application logic while the SR040 autonomously handles UWB timing-critical ranging. The 2.4 GHz BLE link provides OTA firmware updates and gateway communication, and the 6.25-8.25 GHz UWB chain adds location context unavailable in BLE-only designs. Integrated antenna keeps non-RF-focused IoT enclosures compact without external antenna cost.

Secure Fine Ranging / Keyless Entry
UWB's flight-time-based distance bounding is inherently resistant to relay attacks, making the LBUA2ZZ2DK-882 suitable for secure keyless entry systems for vehicles, bikes and shared-equipment lockers. The SR040's 6.25-8.25 GHz UWB channel measures the true distance between the mobile device and the lock, while BLE v5.0 maintains the low-latency wake and authentication channel. Automotive-adjacent designs appreciate the single certified module replacing two discrete radios and their certification programs. Design consideration: the 19.6 x 18.2 mm footprint requires antenna clearance in tight enclosures, and ranging rate should be limited to balance responsiveness against coin-cell battery consumption.
Empfohlen
Wireless Sensor Nodes and Mesh Edge Devices
For battery-powered sensor nodes that must report both data and location, the LBUA2ZZ2DK-882 consolidates connectivity into one component: the QN9090 runs sensor firmware and Bluetooth v5.0 LE communication with gateways, and the SR040 periodically ranging against UWB anchors geotags each report. This eliminates a separate microcontroller in many node designs, reducing BOM count and board area within the 19.6 x 18.2 mm module outline. Low quiescent design supports multi-year operation on primary cells when UWB ranging is infrequent. The integrated chip antenna simplifies enclosure design for plastic IP-rated housings, though range verification through the actual enclosure material is recommended before production.

Wichtigste Unterscheidungsmerkmale
- All-in-one certified UWB + BLE integration (vs. Discrete NXP SR040 + QN9090 chipset design)
- Coin-cell battery operation (vs. Larger UWB modules without low-power optimization)
- Integrated antenna reduces BOM and tuning effort (vs. Modules requiring external antennas)
Designhinweise
The LBUA2ZZ2DK-882 contains an on-board chip antenna, so the PCB layout must respect the antenna keep-out zones defined in Section 6 ("Dimensions, Marking and Terminal Configurations") of the Murata Type 2DK datasheet. Keep metal, ground pour and battery cells out of the clearance region around the module edge; placing the module at a board corner with the antenna facing outward maximizes radiation efficiency. Do not route high-speed signals beneath the antenna area, and verify over-the-air range in the final enclosure because plastic wall thickness and metalized coatings measurably detune the integrated antenna.
Budget power between the two radios: the NXP SR040's UWB ranging bursts in the 6.25-8.25 GHz band dominate energy consumption, while the QN9090's Bluetooth v5.0 LE standby draws far less. For coin-cell designs (per Murata, the module supports coin-cell operation), firmware should keep BLE advertising active for wake-up and provisioning, and trigger UWB ranging only during interaction windows. Provide low-ESR decoupling at the module supply pins per the datasheet, and measure actual average current across your ranging duty cycle rather than relying on peak-current figures alone.
Murata states that specifications of this module may be changed without notice, and the datasheet is marked tentative for some part numbers, so re-verify the datasheet revision at each design milestone. Storage is specified as 5 to 35 degrees C and 20 to 70 percent RH unopened, with packing materials deforming above 40 degrees C; modules held more than 6 months after receipt require solderability confirmation before assembly. Finally, treat the module as single-sourced: Murata's Type 2DK is the only footprint carrying the SR040 + QN9090 combination, so build second-source contingency planning into long-term sourcing.
Compliance-Informationen
Compliance details were not published in the captured web data; JLCPCB lists the part with ROHS marking, but official RoHS/REACH status should be confirmed from Murata's product compliance documents before design-in.
