À l’ère de l’Internet des objets (IdO), Bluetooth Faible consommation d'énergie (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 Bluetooth 5.1 Low Energy module basé sur le Renesas DA14531 jeu de puces. 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 communication sans fil without compromising on power efficiency.
