Overview

The BC840M is a high-performance Bluetooth 5.0, Thread, and Zigbee module based on the Nordic nRF52840 SoC. It features an integrated PCB trace antenna and is designed for multi-protocol IoT applications requiring a high-power ARM Cortex-M4F processor and significant memory overhead.

Why Choose This Part

This module integrates the DC-DC converter inductors and a 32 MHz crystal, reducing the external BOM to a minimum while providing a wide supply voltage range of 1.7V to 5.5V. With 1MB of Flash and 256kB of RAM, it supports complex stacks and over-the-air firmware updates without external memory requirements.

Applications

Smart Home Hubs
Utilizes concurrent protocol support for Zigbee, Thread, and Bluetooth to act as a bridge for diverse home automation devices.
Industrial Mesh Networking
Leverages the IEEE 802.15.4 physical layer and +8dBm output power to maintain reliable long-range mesh connections in noisy environments.
Secure IoT Endpoints
Employs the on-board ARM TrustZone CryptoCell-310 and 128-bit AES hardware encryption for sensitive data protection.
USB-to-Wireless Bridges
The integrated USB 2.0 full speed interface allows for direct connection to PC hosts as a wireless dongle or gateway.
