ECHO is a Programmable Smart Speaker based on the M5ATOM design. Its form factor is very small, its dimensions are only 24 * 24 * 17 mm. Music can be played using the BT capabilities of the ESP32 from a mobile phone or tablet. The device could be programmed to access AWS, Baidu and other cloud platforms, using the built-in microphone and speaker for voice interaction, so that ATOM ECHO has certain AI capabilities, realizing voice control, story telling, 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 BT speaker, it still has the control ability of Atom series.Screw hole on the back is convenient for users to fix.\u003c\/span\u003e\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e\u003cspan style=\"background-color:rgb(254, 146, 0);color:rgb(255, 255, 255);font-size:26px\"\u003e Kindly Remind \u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e\u003cp\u003e\u003cspan style=\"font-size:16px\"\u003e1, The Factory Test firmware is BT speaker, which uses A2DP protocol to transmit audio data(call reception is not supported). After power on, the red LED will be displayed. When the connection with BT device is established, the LED will turn green. At this time, the sound can be output through atom echo. The LED turns red when disconnected. The firmware is compiled on the esp-idf platform. If senior users need to develop other functions by themselves, they can build the environment according to the official documents of Espressif.

offline voice module. The unit offers powerful capabilities such as speech recognition, voiceprint recognition, voice enhancement, and voice detection. It supports AEC (Acoustic Echo Cancellation), effectively removing echoes and noise interference, thereby enhancing voice recognition accuracy. It also supports mid-conversation voice interruption, allowing flexible interruption during voice recognition and quick response to new commands. The product comes pre-configured with 42 English wake-up words and feedback command words. It uses UART serial communication for data transmission and supports awakening the device via UART or voice keywords. The unit also supports user-customizable modification of multi-language wake-up recognition words by regenerating the firmware and can recognize up to 300 command words. Equipped with a microphone for clear audio capture and a built-in speaker for high-quality audio feedback, this product is widely used in AI assistants, smart homes, security monitoring, automotive systems, robotics, smart hardware, and healthcare. It is an ideal choice for implementing intelligent voice interaction.\u003c\/span\u003e\u003cbr\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003cdiv\u003e \u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\u003c\/div\u003e\u003cp
