モノのインターネットの時代に (IoT), Bluetooth低エネルギー (ble) has become the technology of choice for billions of connected devices, thanks to its ultra-low power consumption, robust connectivity, and mature ecosystem. Shenzhen Feasycom introduces the FSC-BT691, a single-mode ブルートゥース 5.1 Low Energy module based on the Renesas DA14531 チップセット. It integrates a high-performance 2.4 GHz transceiver with an ARM® Cortex®-M0+ microcontroller in a compact form factor. Designed for battery-powered and energy-harvesting applications, the FSC-BT691 delivers reliable wireless communication without compromising on power efficiency.
