FSC-BT8902FI Bluetooth 5.2 LE Audio Module

Tags: ,

FSC-BT8902FI is a highly integrated module for BR/EDR/BLE. It allows one active link in either slave mode or master mode. For low energy consumption, it supports multiple states and allows an active link to be in slave mode. BR/EDR link and an LE link can be active at the same time. By default, the FSC-BT8902FI module is equipped with powerful and easy-to-use Feasycom firmware. It's easy to use and completely encapsulated. Feasycom firmware enables users to access Bluetooth functionality with simple ASCII commands delivered to the module over a serial interface, just like a Bluetooth modem. Therefore, FSC-BT8902FI provides an ideal solution for developers who wish to integrate Bluetooth wireless technology into their design.
