Würth Elektronik eiSos is offering the Calypso Wi-Fi module – a compact, fully integrated wireless module for embedded systems in industrial applications. The module is Wi-Fi certified which ensures industry-agreed standards for interoperability, security, and a range of application-specific protocols.
The module, based on the IEEE-802.11-b/g/n standard, has its own antenna on board, but can be optionally operated with an external antenna. The tin-plated edges enable the module to be manually soldered for quick prototyping, as well as AOI (automatic optical inspection) in series production.
Calypso comes with an integrated TCP/IP stack and supports IPv4, IPv6 and common network applications, such as SNTP, DHCP, MQTT, mDNS and HTTP(S). As an alternative to the standard firmware, the customer can select their own firmware, which is uploaded during manufacturing – thus obtaining a customised wireless solution for immediate use.
The AT command interface enables quick and easy expansion of an embedded system to incorporate a Wi-Fi interface. In order to adequately address security issues in industrial Internet-of-Things applications, the module is equipped with six simultaneous secure sockets, secure boot, secure storage and secure OTA (over the air) firmware updates.
The module, with dimensions of just 19 x 27,5 x 4 mm, is designed for operating temperatures of -40°C to +85°C and has a low-power operating mode for battery operated devices. Calypso is pre-certified to save the user development time and costs.
