FSC-BT1026C Qualcomm QCC3024 Bluetooth 5.1 TWS audio receiving module
FSC-BT1026C is a dual-mode Bluetooth based on Qualcomm QCC3024 chip 5.1 The stereo audio SoC module features a high-performance programmable Bluetooth stereo audio SoC, a single-chip dual-mode Bluetooth v5.1 system and a triple-core processor architecture, and uses a low-power design to extend battery life. The FSC-BT1026C Bluetooth audio module supports A2DP, AVRCP, HFP, HSP, SPP, GATT, HOGP and PBAP profiles, as well as SBC and AAC audio codecs, making it suitable for high-end audio applications such as Bluetooth stereo headsets. FSC-BT1026C integrates MCU, RF controller and on-board antenna, and has built-in easy-to-use firmware by default. Developers can quickly integrate Bluetooth functions through simple serial port AT commands, thereby shortening the product design and development cycle.
