FSC-DB008 Arduino Bluetooth Audio Module Evaluation Daughter Board


FSC-DB008 is a plug-and-play daughter development board designed for Arduino UNO, by utilizing Bluetooth module such as FSC-BT966, FSC-BT906, FSC-BT909 Bluetooth module, FSC-DB008 enables the Ardunio developers to evaluate Feasycom Bluetooth audio module in a more efficient way.

Basic Parameter

● The FSC-DB008 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, etc.

● FSC-DB008 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.

1 Why the Serial Monitor app print “Cannot get correct baudrate”?

A: Please check whether the hardware connection between Arduino development board and FSC-DB008 is correct. When FSC-DB008 is working normally, the blue indicator light will flash. When Serial Monitor app prints "mySerialbaudrate = 38400", it means the connection is successful.

2 Why the program upload failed?

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

3 Why can’t I get the response when I send AT-Command ?

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.
