 Product Description 
 
ATOM 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.

 Kindly Remind

1, 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. See the following links for the source code of factory firmware and bin file, where the BIN file burning address is 0x0000.

2, Echo already supports HomeAssistant! The latest shipped devices with the sticker ESPHome FW Pre-installed for HomeAssistant have pre-burned ESPHome firmware, users can refer to the following link .Detailed tutorial reference Tutorials for setting up the M5Stack Atom Echo as a voice assistant for Home Assistant.

For those who are not using Home Assistant, you can flash the device with EasyLoader firmware, to resume the device to Factory Test status.

3, G19 / G22 / G23 / G33 has been defined, please do not reuse the above pins, otherwise ATOM ECHO will be damaged.

Note: please avoid such conditions with M5Stack Atom Echo.

 Product Description 
 
The Atomic Echo Base is a voice recognition base designed specifically for the M5 Atom series. It uses an integrated solution with the ES8311 mono audio decoder, MEMS microphone, and NS4150B power amplifier. The ES8311 offers 24-bit audio resolution and a sample rate of 16KHz to 64KHz, supporting I2S communication and high-fidelity audio processing. The MEMS microphone with high signal-to-noise ratio (SNR) is suitable for automatic speech recognition, while the built-in speaker ensures efficient audio output. The device supports full-duplex communication, enabling simultaneous voice transmission and reception, enhancing interactive features such as speech recognition, wake-up, and audio playback. It is ideal for applications in smart homes and education.
