BC840M, BC840, BC840E Compact nRF52840 Bluetooth 5.3, Thread, Zigbee Module

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

Three modules in the BC840M Series BLE 5.3, Thread, Zigbee modules. They have the same features except size and range.

• BC840M, range 135 meters at 1Mbps; Size, 7.1 (10.1)x12.2x1.5mm.

• BC840, range 4 meters at 1Mbps; Size, 7.1x9.2x1.5mm

• BC840E, range with ANT060 antenna, 850 meters at 1Mbps, 3400 meters at 125 kbps; Size, 7.1x12.2x1.8mm.

BC840E is certified by FCC/ISED with ANT060, a 6 dBi antenna. It is certified with ANT020, a 2 dBi antenna for CE, RCM, and TELEC.

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 Series can deliver high performance in Bluetooth mesh networks.
