Overview

The BT840F is a high-performance Bluetooth v5.0, Thread, and Zigbee module based on the Nordic nRF52840 SoC. It features an integrated trace antenna and an ARM Cortex-M4F processor with 1MB Flash and 256kB RAM, supporting complex multiprotocol wireless applications. With a built-in DC-DC converter and a wide supply voltage range of 1.7V to 5.5V, it is optimized for battery-powered IoT devices.

Why Choose This Part

The module provides a significant 8dBm output power and -96dBm sensitivity for robust long-range communication. Its wide peripheral set, including USB 2.0, I2S, and 12-bit ADC channels, reduces the need for external companion microcontrollers.

Applications

Smart Home Mesh Networking
Leveraging Zigbee and Thread support for interconnected lighting, climate control, and security systems.
Secure IoT Gateways
Utilizing the ARM TrustZone CryptoCell-310 and 12Mbps data rate for secure data aggregation and transmission.
Human Interface Devices
Advanced peripherals including NFC-A for touch-to-pair functionality and 48 GPIO pins for complex input arrays.
