NX40 Module Integration Overview
This section is for developers and hardware engineers who integrate the NX40 module into a custom PCB or host system.
It focuses on practical module-level integration topics such as model selection, PCB integration, pad/pin planning, antenna-related design checks, handling, soldering, and first prototype troubleshooting.
note
This section is not a general Bluetooth introduction. For BLE concepts, see the Bluetooth Intro page. For product-level usage, see the NX40 Series BLE Module pages.
