FSC-BT966C Bluetooth 5.0 Audio Module for Wireless Speakers, Home Automation and Medical Devices


The Feasycom FSC-BT966C is a Bluetooth 5.0 dual-mode module that provides a Bluetooth BR/EDR and LE fully compatible system for audio and data communications. It integrates an application processor with embedded flash memory, a high-performance stereo codec, a power management subsystem, I2S, SPI, LED drivers, PWM, and ADC in a SoC IC. The dual-core architecture with flash memory enables manufacturers to easily differentiate their products with new features without extending development cycles. By default, FSC-BT966C 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 AT commands delivered to the module over serial interface, just like a Bluetooth modem. Therefore, FSC-BT966C provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their design.
