Description
This tiny but powerful board is the perfect board to get sound to your prop. Pair it with a relay and it will activate the relay while the MP3 file is playing. Runs on only 5V so you can use any phone charging brick with at least 2A, but we recommend 3A. What makes this board so great is the 3.5mm on-board audio jack so you can use standard amplified computer speakers to give your project that booming audio. Also has slot for up to 32BG Micro SD card to store the audio files and a Micro USB jack to transfer the files if you don’t have an SD Card reader (Micro USB cable included). Dip switch settings are below in picture gallery.
