These modules are cheap and simple way of building a MP3 player/FM radio. There are different models with minor differences but all of them has the same basic Input/Output.
- Power: Supply voltage is 5V. Exceeding this voltage will damage the module.
- Audio Output: 2 channels. This circuit requires a separate Audio Amplifier and Speakers (+ preamp with tone control) .But you can use a headphone without an amplifier.
- FM Radio: Connect an external antenna for better FM reception.
Connections are marked on the PCB.
Use a voltage regulator (7805) in the supply.
Connectors can be changed to your liking.
