BT40E
Overview
The BT40E is a high-performance Bluetooth 5.4 module based on the Nordic nRF5340 dual-core SoC, featuring an M33 application processor and an M33 network processor. This variant includes a u.FL connector for external antenna flexibility, supporting complex IoT applications that require simultaneous high-speed data and efficient radio management. With 1280KB of Flash and 276KB of RAM, it provides ample resources for large application codebases and protocol stacks.
Why Choose This Part
The module excels in performance-intensive applications by offloading the radio stack to a dedicated network processor, freeing the 128MHz application core for heavy computation. Its support for a wide supply voltage range from 1.7V to 3.6V and an industrial temperature range of -40C to +85C makes it suitable for diverse deployment environments. The u.FL connector allows for optimized antenna placement in metal enclosures where internal trace antennas would fail.
Applications
Key Specifications
Getting Started
Developers can use the Nordic nRF Connect SDK (NCS) and VS Code extension for application development. Since the BT40E is based on the nRF5340, code can be prototyped on the nRF5340-DK before migrating to the Fanstel module footprint. A standard SWD interface is used for programming and debugging the dual-core system.
