FSC-BT3431 BLE 5.1 Low power consumption SIG Mesh Bluetooth module
FSC-BT3431 is a highly integrated small size multi-function BLE 5.1 Bluetooth low energy SoC module. The module supports master-slave integration, multi-connection and SIG mesh technology, and the current in sleep mode and PD mode is as low as 1.4μA and 130nA, making the FSC-BT3431 very suitable for battery-powered applications, including Bluetooth keys, OBUs, smart homes, etc. This module integrates an MCU, RF controller and on-board antenna, and comes with easy-to-use firmware built-in. Developers can quickly integrate Bluetooth functions through simple serial port AT commands, thus shortening the product design and development cycle.
