Review on 🎶 HiLetgo WTV020 SD Audio Player Module for Arduino by Omar Svagera

I finally got it working with my Arduino and I wanted to save the rest of the world some trouble: 1. I failed with nothing but a microSD card with a capacity of 1 GB, which according to the specifications is the maximum size.2. Nothing worked until I formatted the SD card with SDFormatter. I have no idea why - it blew me away.3. Look for "WTV020-SD-16P Audio Module Library". It has examples and makes things easier.4. Despite the description, it does not play native MP3 files, but only a specific format (library for audio module WTV020-SD-16P). There are several conversion tools, but I found a way to export directly from Audacity with the following settings: Mono File Project Rate 16000 Hz (bottom left corner) File > Export Audio. File Type: Other uncompressed files Format Options Header: WAV (Microsoft) Encoding: Unsigned 8-bit PC Save the file as 0###.wav where ### is 000 to 511 Good luck
