GSUB-0002 Overview
An SiP (System-in-Package) module is a higher level of integration than a SoC: multiple dies and passives are assembled inside a single molded package, giving designers a certified, pre-matched radio subsystem. In the wireless hierarchy, the GSUB-0002 sits above discrete RF transceivers and below full application boards - it belongs to the RF module family (RF Misc ICs and Modules) alongside BLE modules and UWB transceiver modules.
What makes the GSUB-0002 notable is its internal architecture. According to the manufacturer documentation and FCC filing, the SiP combines a NORDIC nRF52840 Bluetooth 5 SoC (ARM Cortex-M4F based), a QORVO DW3120 UWB transceiver, an ST LIS2DW12TR 3-axis accelerometer, and a 1.6V step-down switching regulator with matched passive components - effectively a complete secure ranging and communication node in one package.
EMI performance is addressed with sputtered shielding technology on the package, reducing the need for external can shielding on dense boards. Two UWB channels spanning 6GHz to 8.5GHz support IEEE 802.15.4z-style precise ranging applications, while the nRF52840 provides BLE connectivity, application processing, and peripheral I/O.
Typical applications include asset tracking tags, secure key fobs and digital car keys, indoor navigation and real-time location systems (RTLS), and smart door locks where centimeter-level UWB ranging is combined with BLE for connectivity and an accelerometer for wake-on-motion power savings.
Design consideration: because the module integrates its own 1.6V buck regulator, supply-rail design is simplified, but antenna keep-out and ground plane requirements from the datasheet layout guide must be strictly followed to preserve RF performance and regulatory certification.

Typical Applications
GSUB-0002 is suitable for 6 applications: UWB Asset Tracking Tags, Digital Car Keys and Secure Key Fobs, Indoor Navigation and RTLS, Smart Door Locks and Access Control, Wearable and Portable IoT Devices, Robotics and Autonomous Navigation.
UWB Asset Tracking Tags
The GSUB-0002 fits asset tracking tags because it merges UWB precise ranging with BLE connectivity in one pre-certified SiP. The DW3120 UWB transceiver supports 6-8.5 GHz operation with 2 channels for centimeter-level time-of-flight ranging to anchors, while the nRF52840 provides BLE 2.402-2.48 GHz links to smartphones and gateways for provisioning and data offload. In deployment, the tag sits on high-value assets; UWB pulses deliver position updates and BLE handles low-rate telemetry. The integrated LIS2DW12TR accelerometer enables wake-on-motion so the radio subsystem sleeps when the asset is stationary, extending coin-cell battery life substantially. The 10.5 x 8.3 x 1.2 mm footprint and sputtered EMI shielding allow compact, dense tag layouts without external shielding cans.

Digital Car Keys and Secure Key Fobs
Secure passive-entry systems rely on distance bounding to defeat relay attacks, which is precisely what UWB provides. The GSUB-0002's QORVO DW3120 UWB channel delivers time-of-flight measurements accurate to centimeters, and the nRF52840 runs the BLE side of digital-key protocols for phone-to-fob and fob-to-vehicle communication. Because the module is FCC certified under ID 2A5EY-GSUB-0002, fob makers inherit a tested radio subsystem, shortening certification cycles. The accelerometer supports pocket-presence and motion-wake behavior required by automotive key specifications. Typical usage places the module in a fob with a coin cell; the internal 1.6V buck regulator converts the battery rail efficiently, and firmware sequences UWB ranging sessions with BLE advertising to minimize average current draw.
Recommended
Indoor Navigation and RTLS
Real-time location systems need dense anchor-to-tag ranging with low latency, and the GSUB-0002 serves as the mobile node. Its 2-channel UWB capability across 6.25-8.5 GHz supports TDoA and TWR positioning schemes; typical deployments achieve sub-30 cm accuracy in anchor-rich environments. BLE via the nRF52840 backhauls status and assists fallback positioning where UWB anchors are sparse. Host processors connect over SPI for fast UWB data exchange and I2C for sensor access. Because ranging quality depends on clean timing, the module's integrated regulator and shielding reduce on-board noise that would otherwise degrade first-path detection. Designers should place the module at the device edge with antenna keep-outs honored per the datasheet layout guide to preserve angle and range performance.
Recommended
Smart Door Locks and Access Control
Smart locks benefit from the GSUB-0002's combination of secure UWB presence detection and BLE phone connectivity. The DW3120 ranging engine verifies that an authorized key is genuinely within a defined distance - typically 0.5 to 3 meters - before actuating the bolt, preventing both relay attacks and accidental triggers. The nRF52840 manages BLE commissioning, firmware-over-the-air updates, and app communication. The LIS2DW12TR accelerometer adds tamper and knock detection without an external sensor. The module's small LGA footprint integrates into slim lock housings, and FCC modular certification simplifies regulatory filing for the finished lock. Designers should pair the module with a low-power MCU supervising the motor driver and use I2C to poll the accelerometer at low duty cycles to conserve standby power.

Wearable and Portable IoT Devices
Wearables demand extreme integration, and the GSUB-0002's SiP approach removes three chips from the BOM by combining BLE SoC, UWB transceiver, accelerometer, and power regulation in 10.5 x 8.3 x 1.2 mm. Typical wearable uses include proximity-based interaction (unlock when the wearer approaches), secure peer-to-peer ranging between devices, and BLE app connectivity. The internal 1.6V step-down regulator accepts a single Li-ion/LiPo-compatible rail, simplifying the power tree on crowded wearable PCBs. Sputtered EMI shielding prevents radio self-interference with neighboring sensors such as heart-rate optics. Firmware typically keeps the nRF52840 in System ON sleep with accelerometer interrupts enabled, waking UWB ranging only during interactive sessions, which keeps average current within coin-cell or small LiPo budgets.
Recommended
Robotics and Autonomous Navigation
Indoor robots increasingly use UWB as a complement to vision and lidar for absolute position references. The GSUB-0002 gives a robot a two-channel UWB node plus BLE link in one module: the DW3120 exchanges ranging frames with ceiling or wall anchors for meter-level-safe zone verification, while BLE provides teleoperation and diagnostics links. Host robots typically interface over SPI at high clock rates to keep ranging latency low, with the accelerometer contributing vibration or fall detection data over I2C. The module's regulated internal rails tolerate battery bus variation as cells discharge. Because industrial robots add motor noise, the sputtered EMI shielding and careful ground return routing per the datasheet are important to maintain UWB first-path integrity near motor drives.

Key Differentiators
- Complete UWB + BLE + sensing node in one SiP (vs Standalone nRF52840 BLE modules)
- Pre-certified radio subsystem (vs Discrete nRF52840 + DW3120 chip-down design)
- Integrated power conversion with EMI shielding (vs Typical third-party UWB/BLE combo modules)
Design Notes
Follow the GSUB-0002 datasheet layout guide exactly for antenna keep-out and ground plane definitions. The SiP integrates pre-matched passives internally, so no external matching network should be added on the RF pads unless explicitly specified. Place the module at the board edge with antennas facing outward and keep metal, batteries, and display flexes out of the near-field zone. Violating keep-outs degrades UWB first-path detection and can invalidate the FCC modular certification of the end product.
The module generates its 1.6V core rail from an internal step-down switching regulator, so provide a single clean system rail at the datasheet-specified input voltage with the recommended input capacitance placed directly at the supply pad. Because the buck converter switches inside the module, avoid routing sensitive analog traces under the module and give the supply a low-impedance return path to ground. Verify peak current capability for simultaneous BLE TX and UWB ranging bursts, which concentrate current draw in short intervals.
Do not assume this module is interchangeable with BLE-only nRF52840 modules - the 97-pin LGA footprint and UWB section are unique, and no verified drop-in substitute exists as of October 2026. When sourcing, confirm the exact MPN GSUB-0002 with distributors (DigiKey 17005532, LCSC C6050361) to avoid receiving functionally different Goermicro variants. Also budget firmware effort: driving the DW3120 via the nRF52840 requires vendor SDK integration, not just AT-command use.
