Flyron Technology Co., Ltd. FN-BC07 MP3 Sound Module with 15W Amplifier
1. Overviews
1.1. Brief Introduction
FN-BC07 is a high quality MP3 sound module developed by Flyron Technology Co., Ltd. Equipped with an on
board 15W amplifier, the sound module can be controlled by 7 separate buttons hooked up to the “one-on-one"
inputs terminals and by RS485 or UART serial port. When it is playing a sound, it is able to drive an external load
(equipment) like a warning light or a motor simultaneously. Great audio output, industry-grade design and strong
anti-jamming capability make it possible to be used for many different applications.
1.2. Features
1). Equipped with a high quality audio decoder, which supports MP3 and WAV audio formats.
2). Sampling rates supported: 8/11.025/12/16/22.05/24/32/44.1/48(KHz).
3). 24 bit DAC output and supports dynamic range 90dB and SNR 85dB.
4). Supports 7 key control mode, RS485 and UART serial port control modes.
5). In button control mode, it supports eight different trigger modes.
-Able to play 7 one-on-one sound files.
-Able to work as a standard MP3 player.
-Able to play a sound in a loop when power is applied, and any of the seven buttons can interrupt it.
-Able to play multiple sound files per button.
-Set a trigger mode using a config file easily.
6). Uses the built-in SPI flash memory and a micro SD card as the storage devices.
7). Built-in 8MB SPI flash memory and supports max. 32GB micro SD card.
8). Possible to load audio files to the flash memory directly via the micro USB connecting with computer like
using a USB flash drive.
9). Equipped with a class D mono 15 watts amplifier that can drive a max. 15 watts speaker directly.
10). Equipped with a 3.5mm audio jack for stereo output that can drive an earphone directly or connect with an external amplifier.
11). Adjustable sound volume for speaker output through the blue potentiometer.
12). Able to drive an external equipment simultaneously when it is playing a sound.
13). Wide range for power input (DC 9-24V).
14). PCB size: 52mmx49mm
1.3. Technical Parameters
1). Working voltage: DC 9V-24V
2). Working current: ≤2500mA (with external load)
3). Output current to an external load: ≤1000mA
4). Power consumption: ≤25W (with external load)
5). On-board flash memory size: 8MB
6). Audio format: MP3 and WAV
1.4. Connections
K1, K2, K3, K4, K5, K6 and K7 are representing Normally Open (N.O.) manual buttons. TX port and RX port are used for UART
serial control mode, and 485 A and 485 B are used for RS485 control mode. Please refer to the connection example below.
