M5Stack ATOM Echo programmable smart speaker with built-in ESP32 Bluetooth Wi Fi Internet of Things Development Kit
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.
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 .
For those who are not using Home Assistant, you can flash the device with EasyLoader firmware, to resume the device to Factory Test status.

Product details
Kindly Remind:
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:
* DC output from I2S channel
* Playing white noise for a long time
* Playing full square-wave audio
Usage
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.
