M5Stack 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.
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.
