Instruction:
Atom Echo is a programmable smart speaker based on the ATOM design. Extremely compact at just 24 x 24 x 17 mm, it can stream music by connecting—via the ESP32’s wireless functions—to a phone, tablet, etc., or play designated streaming media over Wi-Fi. To simplify voice usage, Atom Echo integrates an STT (speech-to-text) service. Flash the dedicated firmware to enable it and issue voice commands to perform diverse operations. You can also write your own code to connect to cloud platforms such as AWS or Google; using the built-in microphone and speaker, Atom Echo can provide AI capabilities for voice control, smart interaction, IoT, and more. An on-board RGB LED (SK6812) clearly indicates connection status. In addition to serving as a smart speaker, it retains the control abilities of the ATOM series—you can connect external devices through the GROVE port. An M2 screw hole on the back facilitates mounting.
Pin Usage Precautions:G19 / G22 / G23 / G33 have been predefined. Do not reuse these pins; otherwise the Atom Echo may be damaged.Playback Precautions:To prevent damage to the Atom Echo, avoid the following operations:Outputting a DC signal through the I2S channelPlaying white noise for long periodsPlaying full-scale wave square audio
