The DWM1004C is manufactured by Qorvo, a U.S.-based semiconductor company specializing in RF (radio frequency) and IoT (Internet of Things) solutions. Qorvo is known for its wireless connectivity and positioning technologies, including ultra-wideband (UWB) products like the DWM1004C module, which is widely used for precise indoor location tracking. The company serves industries such as automotive, consumer electronics, and industrial IoT.

The DWM1004C module, based on UWB (Ultra-Wideband) technology, is widely used in:
1. Real-Time Location Systems (RTLS) – Asset tracking, personnel monitoring in warehouses, hospitals, and factories.
2. Indoor Positioning – Navigation in GPS-denied environments like malls, airports, and smart buildings.
3. IoT & Smart Devices – Proximity detection, secure access control, and automation.
4. Robotics & Drones – Precise localization and collision avoidance.
5. Automotive & Logistics – Vehicle tracking, smart parking, and warehouse automation.
Its high accuracy (~10cm), low latency, and low power make it ideal for applications requiring reliable indoor positioning.

The DWM1004C is a compact, surface-mount module (SMD) in a QFN (Quad Flat No-leads) package. It measures 15 mm × 15 mm × 2.4 mm and integrates UWB transceiver, MCU, and antenna. Designed for precise indoor positioning, it supports SPI/I2C/UART interfaces and operates at 3.3V. The QFN package ensures efficient thermal performance and space-saving PCB integration.
