FSC-BT825B RTL8761BTV Small-Size Dual-Mode BT 5.3 RF Module
FSC-BT825B is a fully integrated Bluetooth module compliant with the Bluetooth 5.3 specification dual mode protocol (BR/EDR/BLE). It supports various profiles such as SPP, BLE, FTP, ANCS, and iBeacon. The module integrates the baseband controller in a compact package and supports an external antenna, providing designers with greater flexibility in product design. Communication is facilitated through a UART port, and with Feasycom’s Bluetooth stack, customers can easily integrate it into their software, as detailed in the Feasycom stack design guide.
