I have not yet figure out which pin to cut to disconnect the power to the display (I plan to replace the connecting wire with a switch). Another issue is that the LED display is on all the time draining the battery.

For one It is a bit big for a portable player (but it still fits into your shirt pocket). When using anything less than 5V you can only play from a SDCard and not from a USB key. You need to bypass the voltage regulator and solder a connector directly to the unit (I solder it right across the filter capacitor for the voltage regulator) to be able to run it off 18650 (it needs a minimum of about 3.8V to run).

The very cheap “DIY bluetooth car mp3 player/radio with remote” made by Kebidu and sold on aliexpress (bought 4 of them at around 3 dollar each) actually does most of what you are looking for, the most important of which is that it remembers where you were when you stop/power off the device.

It can even play ads in between songs, should you want such a thing.Ĭontrolling the DFPlayer module is easy using serial commands from a microcontroller, making it a convenient subsystem in bigger projects, and a potential alternative to the popular VLSI chips or the hard to come by WT2003S IC.

This tiny module comes packed with a ton of interesting capabilities such as EQ adjustment, volume control, and a 3 watt amplifier amongst other things. You must not take separate gas cartridges on board.When saw DFRobot’s DFPlayer module, he decided he wanted to make his own retro MP3 player.
