FSC-BT671D Xinke EFR32BG21 ultra-long range BLE 5.2 Mesh module
The FSC-BT671D Bluetooth 5.2 low-power SoC module is based on Silicon Labs EFR32BG21 chip and has a built-in 32-bit 80 MHz ARM Cortex-M33 microcontroller. The maximum power output can reach +20 dBm, and the receiving sensitivity is increased to -104.9 dBm (minimum value), which is very suitable for long-distance applications. The module supports Bluetooth Mesh, master-slave integration and multi-connection communication. It uses low-power Gecko technology to ensure fast wake-up time and energy-saving mode. It has a compact design and is ideal for battery-powered applications that require compact size, high performance and low energy consumption. This module is built-in with easy-to-use firmware by default. Developers can quickly integrate Bluetooth functions through simple serial AT commands.
