#59013 I'm trying to build ESP8266 based sound machine for my kid to play soothing sounds like ocean waves, etc. What would be the most efficient way to add external memory to store wav (or other format) files. I know it's simple to add SD card reader but I would like to avoid SD cards if possible.
