Würth Elektronik Wi-Fi® Radio Modules
Würth Elektronik Calypso and Cordelia-I Wi-Fi® modules deliver secure wireless connectivity for industrial IoT applications, but each is optimized for a different challenge. Calypso simplifies wireless integration with a UART-to-cloud architecture, integrated networking protocols, and ready-to-use cloud connectivity, reducing development effort. Würth Elektronik Cordelia-I builds on that foundation with zero-touch provisioning, advanced cybersecurity, and compliance-focused design features that help streamline deployment and support evolving regulatory requirements.
Cordelia-I Wi-Fi IoT Module
The Cordelia-I Wi-Fi IoT Module delivers secure 2.4GHz IEEE 802.11 b/g/n connectivity in a compact form factor, offering up to 400m line-of-sight range and ultra-low-power operation with sleep currents below 10µA. Featuring secure UART-to-cloud connectivity, zero-touch provisioning, and an industrial operating temperature range of –40°C to +85°C, Cordelia-I is ideal for battery-powered and connected IoT applications.
