FSC-DB200 Arduino Bluetooth Audio Module Evaluation Daughter Board

FSC-DB200 is a plug-and-play daughter development board designed for Arduino UNO, by utilizing Bluetooth module such as FSC-BT806A, FSC-BT806B, FSC-BT1006, FSC-BT1026 Bluetooth modules.
FSC-DB200 enables the Ardunio developers to evaluate Feasycom Bluetooth audio module in a more efficient way.


The FSC-DB200 Arduino audio development board includes a Bluetooth module, LINE in, Headphone audio output, MIC input, Type-C power supply, USB-to- UART, LED status indicator, external antenna connector, Arduino reset button, Bluetooth module reset button, CTS/RTS select, SDID output, I2S/SPI select, NEXT/VOL+/Back/VOL-, ON/OFF/PLAY, etc.

FSC-DB200 only occupies ~10 and ~11, other I/Os are open to developers.

We also provide the Arduino example source code to guide developer to program with the Feasycom Bluetooth module.


A: Please check whether the hardware connection between Arduino development board and FSC-DB200 is correct. When FSC-DB200 is working normally, the blue indicator light will flash. When Serial Monitor app prints "mySerialbaudrate = 38400", it means the connection is successful.

A: Please check whether the other software has occupied your serial port. If occupied, please close that software.

A: Please check whether the AT command you sent is correct, . Illegal command will never be responded to. All AT commands should be ended up with New Line and Carriage Return, so select Both NL & CR at the bottom right of the Serial Monitor.
