NX15 Module Overview
The KORLINX NX15 Series is an ultra-compact Bluetooth Low Energy 5.4 module designed for compact wireless IoT products.
Based on the Nordic nRF54L15 platform, the NX15 Series integrates a multi-protocol 2.4 GHz radio, embedded processing, memory resources, security features, and antenna options in a small LGA module package.
NX15 is intended for applications such as BLE sensor nodes, beacons, asset tracking, wearable devices, smart home devices, building automation systems, industrial monitoring nodes, remote controls, and PC peripherals.
What Is NX15?
NX15 is a module-level product intended to be integrated into a custom device or host PCB.
It provides the wireless and processing foundation for Bluetooth Low Energy and 2.4 GHz IoT applications. Developers can use the NX15 module to build compact connected products while reducing the need to design the RF section from the beginning.
This page describes the NX15 module.
For the development board used for evaluation, prototyping, and firmware testing, see the NX15 Dev Kit pages.
