EFR32BG21 Long Range BLE Mesh 5.2 Module | FSC-BT671D

Product Overview

The Bluetooth low energy(BLE) chip used by FSC-BT671D includes a 32-bit 80 MHz ARM Cortex-M33 microcontroller, which can provide a maximum power output of 20dBm. The chip's maximum receiving sensitivity is -97.5 (1 Mbit/s GFSK) dBm, and it supports a complete DSP instruction set and floating point unit, which can speed up calculations. Low-power gecko technology supports fast wake-up time and energy-saving mode. FSC-BT671D software and SDK support Bluetooth Low Energy (LE), Bluetooth 5.2 and Bluetooth mesh network. The module also supports the development of proprietary wireless protocols.

FSC-BT671D combines an energy-friendly MCU with a highly integrated radio transceiver. The module is suited for any battery operated application other systems requiring high performance and low energy consumption.

Support communicating with the FeasyBlue app and many other Bluetooth apps.
