Thread NCP

The KTWM102 series is a fully-integrated IEEE 802.15.4 Network Co-Processor module that provides an easy, cost-effective way for manufacturers to add Thread connectivity to their products. It comes with optional integrated chip antenna or W.FL connector to easily adapt to network environment.

Tiny Footprint

Surface-mount component with solder pads on the bottom for I/O and PWR/GND connections. It has an extremely small form factor for size-constrained applications.

Powered by KiNOS

Take advantage of the best-in-class Thread Certified Stack and focus on your core business. The module runs the full IEEE 802.15.4 and Thread networking stacks to significantly offload the host or application microcontroller and simplify system integration. Alternatively, it can be run self-contained without a host.

Easy Integration

It provides a high-speed serial to Thread connection through UART interface. This application-agnostic interface delivers seamless traffic integration with the host microcontroller. The KTWM102 also features native USB 2.0 support to meet design requirements of an embedded Border Router.

Modular Certification

Ideal solution for organizations with limited Thread or RF expertise or for those seeking faster time-to-market, as it reduces RF design time and removes the burden of testing and certification. The module meets major global regulatory requirements including USA, Canada and EU.

Battery-Friendly

The KTWM102 series combines the world’s most energy-efficient microprocessor architecture with the most sophisticated power-saving techniques provided by KiNOS to lead to ultra-low-power for battery-operated applications.
