 **ATOM ECHO**  is a programmable smart speaker designed based on ATOM. It has a small size with only 24 * 24 * 17 mm. Music can be played by bluetooth of ESP32 with mobile phones and tablets, and you can also play the specified streaming music through WiFi. In order to facilitate the usage of speech function, we have integrated STT (speech to text) service in ATOM ECHO. You can use this function by burning the specified firmware, and complete various operations by voice command. Of course, you can access AWS, GOOGLE and other cloud platforms by writing code and using built-in microphone and speaker for speech interaction. In that way, ATOM ECHO possesses certain AI capabilities like realizing voice control, intelligent conversation, internet of things and other functions. The speaker is embedded with an RGB LED (SK6812) which can visually display the connection status. In addition to being used as a bluetooth speaker, it still has the control ability of ATOM series. You can connect the device through the GROVE interface. G21 / G25 can only be used for general I/O, they do not support I2C and UART. cScrew hole on the back is convenient for users to fix.
 
-?>**Note: the product can not be used for a long time. It is recommended to play music for about 1 hour. It is not allowed to play low-frequency and heavy music, otherwise the speaker will be damaged.**

 **ATOM ECHO**是一款基于ATOM设计的可编程智能音箱，它的体积非常小巧，只有24*24*17毫米，通过ESP32自带的蓝牙功能与手机、平板等进行连接即可播放音乐，也可以通过WIFI播放指定的流媒体音乐。为了方便用户使用语音功能，我们在ATOM ECHO内集成了STT(语音转文字)服务，您可以通过烧录指定固件开启该功能，通过语音下达指令完成多样化的操作。当然，您还可以通过自行编写代码接入AWS、GOOGLE等云平台，使用内置麦克风和扬声器进行语音交互，使得ATOM ECHO具备一定的AI能力，实现语音控制、智能对话、物联网等功能。音箱内嵌一颗RGB LED（SK6812)，可以直观的显示连接状态。除了可以作为智能音箱使用外，它依然具备了ATOM系列的控制能力，你可以通过GROVE接口连接外部设备，G21/G25仅能用于通用IO，不支持UART与I2C。其背面有一个M2螺丝孔，方便用户进行固定。
 
-?> **注意：产品不可长时间使用，音乐播放建议在1小时左右，不可播放低频过重的音乐，否则将损坏扬声器。**
