NINA-W13 Series - Secure Wi-Fi IoT modules with pre-flashed connectivity software for industrial markets

Compact stand-alone 802.11 b/g/n Wi-Fi modules

The NINA-W13 series is a small stand-alone wireless MCU module that integrates a powerful microcontroller (MCU) and a radio for wireless communication. The NINA-W13x modules come with pre-flashed application software, supporting 802.11b/g/n in the 2.4 GHz ISM band. The host system can set up and control the module through the AT command interface. This greatly reduces the time and complexity to add Wi-Fi connectivity to the end product.

NINA-W13 modules provide top grade security, thanks to secure boot, which ensures the module boots up only with original u-blox software. In addition, they will provide end-to-end security on the wireless link with the latest 802.11i (WPA2) standard and enterprise security to provide a secure connection to the infrastructure. This makes NINA-W13 ideal for critical IoT applications where security is important.

Intended applications include telematics, low power sensors, connected factories, connected buildings (appliances and surveillance), point-of-sales, and health devices.

Device design is simplified as developers can choose to either use an external antenna (NINA-W131) or take advantage of the internal antenna (NINA-W132). Additionally, the NINA-W13 modules are pin-compatible with the NINA-B1 Bluetooth low energy modules, thus offering maximum flexibility for development of similar devices offering different radio technologies.

NINA-W1 will initially be certified for the US, Europe, and Canada. Certifications for other countries are planned. The modules will be qualified for professional grade operation, supporting an extended temperature range of -40 °C to +85 °C.
