BT840, Low Cost nRF52840 Bluetooth 5, Thread, Zigbee Module

 

BT840

 

BT840 is an advanced, highly flexible solution for today's increasingly demanding Ultra Low Power, Ultra Long Range, and higher throughput applications in the IoT world. Inherent industry-grade security is essential in today's applications, an cryptographic accelerator is embedded.

BT840 is a lower cost, smaller size, shorter range alternative of BT840F. Both have identical soldering pad footprints. BT840 production will begin in Dec. 2017. For prototyping, please use BT840F, available now. 

Sister module BT840E has an u.FL connector for external connector.

BT840 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.
  • BT840 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, BT840 can deliver high performance in Bluetooth mesh networks.
