Today we are getting right into Bluetooth Audio Receivers in particular the MH-M38. The MH-M38 is a stereo audio receiver with loudspeaker outputs (and an inbuilt amplifier) that can play music from a smartphone/computer, without wires, via Bluetooth. These tiny boards pack a huge punch, letting you drive two 5W speakers very loud, and doing so with a connectivity range of over 20 metres! This board operates with a modern Bluetooth transmission protocol. the Bluetooth V4.2 version. This module supports Bluetooth automatic re-connection technology, supports WAV / WMA / FLAC / APE / MP3 lossless decoding, and has stereo two-channel output.

Did you ever test the module by connecting the USB port to a PC? Allegedly it functions as a sound card. I'd be interested to see how that works out.

Would it be a problem to use 1Watt speakers? Or is that too low?

@Core-Electronics Жыл бұрын

The datasheet states that it will work with speakers ranging from 2-8 ohm to 3-5W, but the optimum speaker for this devices is 4 Ohms at 5 Watts. I think 1 Watt might not be the best for this module.

What if i have two 10W speakers? Can i still use this module?

@Core-Electronics 8 ай бұрын

That shouldn't be an issue as long as the impedance values match. The 10W speaker just won't be as loud as it could if you drove it with a larger signal.

IT IS LOUD my parents can hear it even though it is at one volume

You can always refine (lower) the output from your computer source 😊 so you don't drive your parents up the wall.
