Categories:
FSC-BT1037A

The Feasycom FSC-BT1037A is a dual-mode Bluetooth 5.3 LE Audio module that supports audio and data communication. FSC-BT1037A integrates an ultra-low-power PMU and application processor with embedded flash memory, a high-performance stereo codec, Class-AB and Class-D headphone drivers, a power management subsystem, I2S, I2C, UART, PIO, LED drivers and ADC I/O in a SoC IC. Both cores use external flash to execute code, making it easy for user to differentiate products from new features without delaying the development.
