What is the best ESP32 board and audio playback solution for a smart clock with NTP synchronization?
Hello @Daniel kalu For your compact smart clock project, I recommend using the
ESP32-WROOM-32 module due to its small size and adequate processing power for your needs. For audio playback, you can use an external I2S DAC like the MAX98357A, which is well-suited for playing MP3 or WAV files. To synchronize the time with NTP servers, you can use the NTPClient library, and for scheduling audio playback, the Ticker library is a reliable choice. Make sure you use efficient coding practices to manage the timing and synchronization to keep the operations smooth and reliable.4 replies
