NX15 Series BLE Module Overview
The NX15 Series is a compact Bluetooth Low Energy module designed for low-power IoT products, sensors, beacons, wearables, smart home devices, and embedded wireless applications.
It is based on the Nordic nRF54L15 SoC and supports Bluetooth LE 5.4. Depending on the software stack, it can also be used for 802.15.4-based applications such as Thread, Zigbee, and Matter over Thread.
This overview provides a short introduction only. For hardware design, antenna layout, low-power optimization, and application development, continue to the dedicated pages listed below.
