BT840E, Nordic nRF52840 Bluetooth 5, Thread, Zigbee Module, External Antenna
BT840E 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.
BT840E should be used with ANT060 external antenna when extra long range or omni directional antenna is required.
BT840E and BT840F have identical soldering pad footprints. BT840E production will begin in Dec. 2017. For prototyping, please use BT840F, available now.

BT840E 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.
- Range between two BT840Es is estimated at over 1000 meters.
- ANT060 antenna is omni directional.
- 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. Security is mandatory in Bluetooth mesh networks. By offloading decryption, encryption, and authentication works to CryptoCell-310, BT840E can deliver high performance in Bluetooth mesh networks.
