Atom-Echo is a programmable smart speaker based on the ATOM design, with a very compact size of only 24 x 24 x 17mm. It can connect to mobile phones, tablets, etc., via the ESP32's built-in wireless capabilities to play music, or stream specified media via WIFI. To facilitate the use of voice functions, we have integrated STT (Speech-to-Text) services into Atom-Echo. You can enable this feature by flashing specific firmware, allowing you to perform various operations through voice commands. Additionally, you can write your own code to connect to cloud platforms like AWS and Google, using the built-in microphone and speaker for voice interactions, giving Atom-Echo some AI capabilities to achieve voice control, smart conversations, IoT functions, and more. The speaker has an embedded RGB LED (SK6812) that visually displays the connection status. Besides being a smart speaker, it retains the control capabilities of the ATOM series, allowing you to connect external devices via the GROVE interface. There is an M2 screw hole on the back for easy mounting.
