NORA-W2 Expresslink Multiradio Modules u-blox NORA-W2 Expresslink Multiradio Modules are stand-alone modules integrating a powerful 32-bit dual-core Microcontroller Unit (MCU) and a radio for wireless communication. These modules provide out-of-the-box connectivity with Amazon Web Services (AWS). The NORA-W2 modules support secure Over-The-Air (OTA) updates of the module firmware and the host application. These modules use stateless AT commands for control and data communication over a serial interface. The NORA-W2 multi-radio modules are designed with a secure boot, ensuring that modules will boot up only in the presence of authenticated software. These modules are well-suited for critical IoT applications where security is paramount. The NORA-W2 modules are industrial grade and qualified according to ISO 16750 to withstand harsh environments. These user-friendly modules support an extended temperature range of -40°C to 85°C.
