FSC-BT836 RTL8761 Dual-Mode BT 4.2 High-Output-Power Module
FSC-BT836 is a dual-mode (BR/EDR and LE) Bluetooth 4.2 compliant module, supporting profiles like SPP, HID, GATT, and ATT. It offers customizable hardware interfaces such as UART, USB, PCM, I²C, AIO, and PIO. Incorporating a high-performance MCU, Bluetooth controller, and chip antenna in a small package, it allows for easy integration into compact products. Programming is done through the UART interface using AT commands to configure the module, leveraging Feasycom’s Bluetooth stack for enhanced application possibilities. For programming details, refer to the relevant user guide.
