Ezurio Sera NX040 Ultra-Wide Band & BLUETOOTH® LE Modules

Ezurio Sera NX040 Ultra-Wide Band (UWB) and BLUETOOTH® LE (BLE) Modules feature tightly integrated hardware and RF designs, all optimized for low-power operation and reducing the need for external clocks, filters, and components. The Sera NX040 modules integrate an NXP SR040 chipset for UWB and the nRF52833 silicon from Nordic Semiconductor for BLE. Antenna options include internal PCB trace antennas for UWB and BLE or externally via two MHF4L connectors. These devices easily advance basic beaconing or RSSI-based ranging BLE with NFC and UWB for more granular locationing and positioning. This granularity yields much higher accuracy than RSSI-only proximity applications in industrial, consumer, automotive, and IoT environments.
