FSC-BT691 Dialog DA14531 BLE 5.1 Mini Beacon SoC Module Low Energy

FSC-BT691 is a Bluetooth Low Energy (BLE) 5.1 ultra-low-power and small-size SoC Module featuring a 2.4 GHz transceiver and an ARM Cortex-M0+ microcontroller. Its low active RF and MCU current consumption, along with low-power mode operation, ensure extended battery life suitable for small coin cell and energy-harvesting applications. The module comes with easy-to-use firmware, developers can use simple UART AT commands to integrate Bluetooth functions. It is designed for a wide range of applications including disposables, wireless sensor nodes, beacons, proximity tags, trackers, and trackpads, as well as toys, and medical and industrial applications.
