Hi, I have set up my DFplayer mini using just the I/O mode (no arduino board) as per the set up [I_O%20mode] . Putting my small 30mm diameter 8ohm, 2 W speaker in either the SPK1 or the DAC_R pins and get a very very quiet output. Is my speaker just too small? Is this the right impedance? / watt…

I’d go with a higher impedance speaker - and don’t connect the speaker directly to the DAC pins. The 3W amp is connected to SPK1 & 2. Are you powering the module with 5V or 3.3V? Have you tried volume control?

i have used a 8ohm .5 watt speaker before with a similar low power output and it was good sound loudness, although it was a quite small speaker. 2 watt or over speakers better to have 4ohm unless you plan to add an external amplifier to the mix.

in context to the connection diagram you should check your resistance used. "Note: For simple use ,the upper diagram is ready,But if you find the noise is quite loud, then you could attach an 1K resistor to the TX pin." In your case, it is too quiet, which resistance did you use where? Like to po…

Did you set the speaker volume to the max in the setup() ? I have something like… void setup() { ... mp3_set_volume (0x30); // Set the volume to max } void execute_CMD(byte CMD, byte Par1, byte Par2) { // Calculate the checksum (2 bytes) int16_t checksum = -(Version_Byte + Command_L…

I finally had time this week to sit down and troubleshoot a bit. Only after trying several different speakers that I had around, did I realize that it was actually the waffle board that Ihad my initial setup on that was not providing a very good connection. I went ahead and soldered everything toget…
