BT40
Overview
The BT40 is a high-performance Bluetooth Low Energy 5.4 module based on the Nordic Semiconductor nRF5340 dual-core SoC. It features a PCB trace antenna and leverages the power of two ARM Cortex-M33 processors to separate application code from network protocol processing.
Why Choose This Part
The dual-core architecture allows the 128MHz application core to run complex algorithms without interrupting the 64MHz network core's timing-critical radio operations. It offers a large memory footprint with 1280KB Flash and 276KB RAM, ensuring sufficient space for sophisticated firmware and over-the-air updates.

Key Specifications
Getting Started
Developers can use the Nordic nRF Connect SDK and Segger Embedded Studio or VS Code for firmware development. Hardware evaluation is typically performed using Fanstel's EV-BT40 evaluation board, which breaks out the module's GPIOs for easy prototyping.
