Mini MP3 Player

The DFPlayer Mini is a super-compact and budget-friendly MP3 module. It can be directly hooked up to a speaker. You can use this module independently with a battery power supply, a speaker, and a keypad. Or, you can control it through the serial port, just like you would with an Arduino UNO or any microcontroller with a serial port. It comes with perfectly integrated hardware for decoding MP3, WAV, and WMA files. The software supports the TF card driver for FAT16 and FAT32 file systems. With simple serial commands, you can play specific music and access other playback functions. It's incredibly easy to use, stable, and reliable! Key features include support for multiple sampling rates (8 / 11.025 / 12 / 16 / 22.05 / 24 / 32 / 44.1 / 48 KHz), 24-bit DAC output with 90dB dynamic range and 85dB SNR. It fully supports FAT16 and FAT32 file systems, with a maximum support of 32G for TF cards and USB drives, along with 64M bytes of NORFLASH. There are various control modes such as IO control, serial mode, and AD key control. It has a broadcast language spots feature that allows you to pause background music during ads and resume playback after. Audio data can be sorted into up to 100 folders, with each folder able to hold 255 tracks. The volume is adjustable in 30 levels, and the EQ can be adjusted in 6 levels. This module is great for a wide range of applications like car navigation voice broadcasts, voice prompts at transport inspection points and fee stations, security check voice prompts at train and bus stations, voice prompts in power, telecom, and financial operating rooms, multi - channel voice alarms or guidance for equipment operation, failure alarms for electrical and mechanical equipment, fire alarm voice prompts, and automatic/regular broadcasting equipment. The package includes 1 Mini MP3 Player. There are also useful resources like Arduino Library V2.0, a User Manual, and an SVG File.

Using the Mini MP3 Player is a breeze. First, connect it to a power source like a battery. Then, you can either connect it to a speaker directly or use a serial port to control it with a microcontroller. If you're using a TF card or a USB drive, make sure it's formatted in FAT16 or FAT32. You can sort your audio files into folders to keep things organized. To play specific music, just use the simple serial commands. You can adjust the volume in 30 levels and the EQ in 6 levels to get the best sound. When using the broadcast language spots feature, the module will pause the background music while an ad is playing and then resume it automatically. As for maintenance, keep the module clean and dry. Avoid exposing it to extreme temperatures or humidity. If you're using a TF card or USB drive, handle them carefully to prevent data loss. When not in use, disconnect the power supply to save energy and prolong the life of the module. Also, refer to the User Manual for more detailed information and troubleshooting tips.
