FSC-BT691 Dialog DA14531 Ultra-low power consumption BLE 5.1 Bluetooth module
FSC-BT691 is a Bluetooth BLE 5.1 technology, ultra-low power and compact (SoC) module, equipped with 2.4 GHz transceiver with ARM Cortex-M0+ microcontroller. Its low-frequency active RF and microcontroller current consumption, coupled with low-power mode operation, ensures extremely long battery life, making it ideal for small button batteries and power-sensitive applications. The module is suitable for a variety of applications including disposables, wireless sensor nodes, beacons, proximity tags, trackers, as well as toys, medical and industrial applications. This module integrates MCU, RF control components and on-board antenna. It comes with easy-to-use firmware built-in by default. Developers can quickly integrate Bluetooth functions through simple serial AT commands, thereby shortening the product design and development cycle.
