FSC-DB008 User Guide

[中文版]

This guide will introduce how to use the FSC-DB008 audio and data transmission development board, and provide more information about this development board.

Overview

The FSC-DB008 Development Board integrates Type-C (supporting UART/USB/charging/power supply), audio input/output, a microphone, a lithium battery, buttons, a reset button, 2.54mm-pitch pin headers, and status indicator LEDs. It can be used with our company’s serial assistant and AT commands for function testing, helping customers familiarize themselves with our products, shorten the development cycle, and improve efficiency.

The FSC-DB008 is also a plug-and-play sub-development board designed specifically for Arduino UNO, enabling Arduino developers to evaluate Feasycom Bluetooth audio modules more effectively.

What You Need

Required Hardware

  • 1 x FSC-DB008-BT1036B Development KIT : FSC-DB008 development board pre-integrated with a FSC-BT1036B (optional)

  • 1 x USB-to-Type-C data cable

  • 1 x PC(Windows / Mac)

  • 1 x Mobile phone or music player

  • 1 x AUX 3.5mm audio cable (optional)

  • 1 x Bluetooth speaker or wired audio input Bluetooth headset (optional)

Software and Setup

  • Serial Driver : FT232r_Universal_Windows_Driver.zip for Windows PC, generally plug-and-play, install this driver if the PC fails to recognize the device in specific environments.

  • Feasycom Serial Port Tool : A serial communication analysis tool based on Windows PC.

  • FeasyBlue :Feasycom APP & SDK resource supporting Android and iOS platforms, which enables functions such as Bluetooth BLE & SPP data communication debugging, Feasycom module firmware version reading, firmware OTA upgrade,parameter configuration, etc.

  • Communication Interface:UART

  • UART Configuration:115200/8/N/1(Feasycom general firmware default)

Hardware Access

Power-on Options

The development board can be powered by any one of the following methods:

  • Type-C power supply (default)

  • 3V3 / GND pin power supply

Note:Do not connect the above power supply modes simultaneously, as this may damage the development board and/or the power supply.

Hardware Access Note

  • Before power-on, confirm that the development board is intact and that no components are loose or stuck together.

  • Connect the development board to the PC using a USB-to-Type-C cable.

  • After power-on, the LEDs on the development board flash, indicating that the module is operational and ready for debugging.

Quick Start

Hardware Access and Start

Connect the Type-C port (Component 8) of the development board (FSC-DB008-BT1036B) to the PC using a USB-to-Type-C cable. A slow flash of Indicator LED (LED1) indicates that the module has started normally.

Serial Port Recognition

The device supports plug-and-play (no additional component control required). The PC will recognize the USB serial device and generate a virtual COMx port.

db008

AT - Serial Communication Test

Open the Feasycom Serial Debug Assistant on the PC.Automatically detect or manually select the corresponding serial port (COMx),set the matching baud rate,(e.g., 115200), check Send New Line, and send the serial communication test command AT , If the response is OK , the serial communication test is successful. The command format and example are shown below:

Command

AT\r\n

Response

\r\nOK\r\n

Description

Test the UART communication between HOST and Module after power on, baudrate changed, etc.

Example:

send:     >>AT\r\n               
response: <<\r\nOK\r\n   //Successfully connected.
