FSC-BT1026C Qualcomm QCC3024 Bluetooth 5.1 Audio Receiver Module
FSC-BT1026C is a dual-mode Bluetooth 5.1 stereo audio receiver SoC module based on Qualcomm QCC3024 chip, explicitly designed for wireless audio applications. The module integrates Bluetooth 5.1 dual-mode (BR/EDR + BLE) technology, supports Bluetooth protocols such as A2DP, AVRCP, HFP, HSP, SPP, GATT, and PBAP, and supports high-quality audio transmission and low-power Bluetooth connections. It can be widely used in wireless headphones, Bluetooth speakers, Car Bluetooth, and other products. The module comes with powerful, easy-to-use firmware; developers can use simple UART AT commands to integrate Bluetooth audio functionality.
