FSC-BT1026E Qualcomm QCC5125 Bluetooth 5.1 ANC HiFi audio receiving module
FSC-BT1026E is a dual-mode Bluetooth based on Qualcomm QCC5125 chip 5.1 HiFi audio SoC module has a triple-core processor architecture, high-performance Bluetooth audio SoC, flexible flash memory programmable platform, and ultra-low power consumption design, which can effectively extend battery life. The FSC-BT1026E Bluetooth audio module is designed for high-end HiFi audio applications and supports A2DP, AVRCP, HFP, HSP, SPP, GATT, HOGP and PBAP protocols, as well as Qualcomm's aptX Audio technology (aptX, aptX HD, aptX Low Latency and aptX Adaptive), and supports SBC and AAC audio codecs. FSC-BT1026E integrates MCU, RF controller and on-board antenna. It 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.
