BC840, Compact nRF52840 Bluetooth 5, Thread, Zigbee Module
BC840 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, a cryptographic accelerator is embedded.
Sister module BC840M is is slightly large(7.0x12.0x1.5mm), longer range alternative of BC840. Both have identical soldering pad footprints.
Sister module BC840E has an u.FL connector for external connector.

BC840 Advanced Features
Bluetooth 5 datarate: 2Mbps, 1Mbps, 500 Kbps, 125 kbps
IEEE 802.15.4 Thread and Zigbee
Nordic 2.4 GHz proprietary
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.
Embedded CryptoCell 310 co-processor can be used to provide more secure connection and to prevent hacker.
BC840 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, BC840 can deliver high performance in Bluetooth mesh networks.
