BC840M, Long Range, Compact nRF52840 Bluetooth 5, Thread, Zigbee Module

 

BC840M

 

BC840M is an advanced, highly flexible solution for today's increasingly demanding Ultra Low Power, Long Range, and higher throughput applications in the IoT world. Inherent industry-grade security is essential in today's applications, a cryptographic accelerator is embedded.

BC840M is a compact (7.0x12.0x1.5mm, antenna area width 10.0mm), long range BLE 5, Thread, Zigbee modules.

Sister module BC840 is a smaller size (7.0x9.0x1.5mm), short range alternative.

Sister module BC840E has an u.FL connector for external connector.

BC840M Advanced Features

Protocols

  • Bluetooth 5 datarate: 2Mbps, 1Mbps, 500 Kbps, 125 kbps

  • IEEE 802.15.4 Thread and Zigbee

  • ANT/ANT+

  • Nordic 2.4 GHz proprietary

Power Supply

  • 1.7V to 3.6V DC power supply

  • High voltage power supply to accept up to 5.5V DC for direct connection to Lithium batteries or 5V system power. An external voltage regulator is not required. Your total system cost can be lower and your PCB size can be smaller.

Security

  • Embedded CryptoCell 310 co-processor can be used to provide more secure connection and to prevent hacker.

  • BC840M is required if your Bluetooth 5 devices are used in mesh networks with many nodes for desirable performance. Security is mandatory in Bluetooth mesh networks. By offloading decryption, encryption, and authentication works to CryptoCell-310, BC840M can deliver high performance in Bluetooth mesh networks.
