FSC BT1026E 1

In the fast-growing wireless audio industry, a high-performance Bluetooth audio receiver module is the key to creating standout products. Feasycom’s FSC-BT1026E module, powered by the Qualcomm QCC5125 chipset and Bluetooth 5.1 dual-mode technology, emerges as a leading choice for developers aiming to deliver premium audio experiences. It integrates powerful processing capabilities, top-tier sound quality, and flexible integration feature.

 

Strong Processor & Stable Bluetooth 5.1

At the heart of the FSC-BT1026E lies a robust tri-core processor setup: a 120 MHz Qualcomm Kalimba audio DSP and a 32 MHz developer processor. This architecture enables seamless handling of Bluetooth protocol operations and complex audio processing tasks, ensuring smooth performance even under heavy loads. Supporting Bluetooth 5.1 dual mode, the module maintains backward compatibility with versions ranging from 5.0/4.0 down to 1.1, ensuring broad connectivity with various devices. With a maximum transmit power of +9 dBm and a typical receive sensitivity of -96 dBm, it delivers stable signal transmission in crowded wireless environments, effectively eliminating audio dropouts and lag that often plague inferior modules.

Premium Codecs & HiFi Sound

Audio quality is where the FSC-BT1026E truly excels. It supports a suite of premium audio codecs, including aptX, aptX HD, aptX Adaptive, SBC, and AAC (note that aptX technologies require Qualcomm licenses), enabling studio-grade HiFi sound reproduction. Equipped with a 24-bit audio interface, its ADC and DAC components handle sample rates up to 96 kHz (with the DAC supporting up to 384 kHz), capturing every nuance of the original audio—from crisp highs to deep, resonant bass. Complemented by Qualcomm’s cVc noise cancellation technology, it significantly reduces background interference during calls and audio playback, enhancing clarity for users in various settings.

 

Versatile Interfaces & Compact Design

Versatility and ease of integration make the FSC-BT1026E a favorite among developers. It comes with a comprehensive range of interfaces, including UART, I2C, SPI, USB 2.0, I²S/PCM, ADC, and DAC, facilitating seamless connections to different components. The 23 GPIO pins and PWM-supported LED pins allow for custom function expansion and visual feedback design, adding flexibility to product development. With a compact form factor of 13mm×26.9mm×2.2mm and a 52-pin stamp package, it fits effortlessly into space-constrained devices like compact headphones and portable speakers. The integrated PMU (Power Management Unit) with dual SMPS and Li-ion battery charger simplifies power circuit design, while low-power modes extend the battery life of portable audio products—a crucial factor for user experience.

 

Easy Customization & Wide Adaptability

Moreover, the module supports OTA (Over-the-Air) upgrades and in-depth firmware customization, enabling developers to adapt it to specific application requirements and roll out feature updates post-launch. It complies with multiple Bluetooth profiles such as A2DP, AVRCP, HFP, SPP, and GATT, and holds BQB certification, ensuring global compatibility and regulatory compliance. With an operating temperature range of -40°C to +85°C, it performs reliably in diverse environmental conditions, from cold outdoor settings to warm indoor spaces.

For developers and manufacturers focusing on high-end wireless audio devices, the FSC-BT1026E Bluetooth audio receiver module offers an all-in-one solution that combines exceptional sound quality, robust connectivity, and flexible integration. It empowers products to stand out in a competitive market, delivering the premium experience that modern consumers demand.
