FSC-BT802B

The Feasycom FSC-BT802B is a Bluetooth 5.1 dual-mode audio module. It provides a Bluetooth Low Energy fully compliant system for audio and data communication with Feasycom stack. FSC-BT802B integrates an ultra-low-power DSP and application processor with embedded flash memory, a high-performance stereo codec, a power management subsystem, SPI, LED drivers and ADC 1/0 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-BT802B 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 ASCIl commands delivered to the module over serial interface - it's just like a Bluetooth modem. Therefore, FSC-BT802B provides an ideal solution for developers who want to integrate Bluetooth wireless technology into their design.
