FSC-DB004-PIN User Guide
This guide introduces how to use the FSC-DB004-PIN and provides further information about this development board.
Overview
FSC-DB004-PIN development board supports Arduino Bluetooth connection development. It is compatible with various 13mm×26.9mm stamp 36-pin packaged Bluetooth modules, such as the FSC-BT616, FSC-BT618, FSC-BT826 Series, FSC-BT836 Series, and FSC-BT9101 Series, which are designed for data transmission applications.
Compared with using a single Bluetooth module, the FSC-DB004-PIN development board offers greater convenience and usability for users to quickly test products, thereby saving time during the testing process and ensuring safety.

Communication Interface : UART
UART Configuration: 115200/8/N/1 (Feasycom general firmware default)
Hardware Access
Power-on
3V3 / GND pin power supply
Hardware Access Note
Before powering on, ensure the development board is intact and all components are secure without looseness or shorts;
Development Board A (FSC-DB004-BT9101AI) and Development Board B (USB-TTL Serial Converter) are connected via Dupont wires for TXD/RXD/VCC/GND, and Development Board B (USB-TTL Serial Converter) is connected to the PC via USB;
After power-on, the LED indicator of Development Board A (FSC-DB004-BT9101AI) flashes continuously, indicating that the development board has been successfully powered on and the Bluetooth module has been connected.
Communication Test
1.Power Supply Connection
Connect the intact Development Board A (FSC-DB004-BT9101AI) and Development Board B (USB-TTL Serial Converter) via Dupont wires for TXD/RXD/VCC/GND, and Development Board B (USB-TTL Serial Converter) is connected to the PC via USB.
2.Serial Port Recognition
The PC detects the USB serial device and generates a virtual COMx.

3.UART Communication Test
Run the Feasycom Serial Port Tool on the PC, set the correct COM and Baud, and check the New Line.
Send the UART communication test command AT. If the response is OK, it indicates the serial communication test is successful.
