Its form factor is very small, its dimensions are only 24 * 24 * 17 mm. Music can be played using the Bluetooth 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 ECH 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 Bluetooth speaker, it still has the control ability of Atom series. You can connect devices through the grove interface, G21 \/ G25 can only be used for general I\/O, they do not support I2C and UART.Screw hole on the back is convenient for users to fix. \u003cbr\u003e\n \u003cbr\u003e\nNote: This product is not recommended to play low-frequency or heavy music for a long time. \u003cbr\u003e\n \u003cbr\u003e\nProduct Features: \u003cbr\u003e\nLight and small; \u003cbr\u003e\nSupport STT services; \u003cbr\u003e\nBased on ESP32, Support A2DP, BLE 4.0; \u003cbr\u003e\n2.4G WiFi IEEE 802.11b\/g\/n; \u003cbr\u003e\nBuilt-in microphone and speaker; \u003cbr\u003e\nRGB LED status display indication; \u003cbr\u003e\nGROVE extension interface; \u003cbr\u003e\nRecord and playback; \u003cbr\u003e\nProgrammable key; \u003cbr\u003e\nProgramming platform:Ard、ESP-IDF\/ADF; \u003cbr\u003e\nInclude: \u003cbr\u003e\n1x ATOM ECH; \u003cbr\u003e\nApplications: \u003cbr\u003e\nBluetooth Speaker; \u003cbr\u003e\nVoice control; \u003cbr\u003e\nIoT; \u003cbr\u003e\nSpecification: \u003cbr\u003e\nResources: Parameter; \u003cbr\u003e\nSoC: ESP-PICO-D4,240MHz,Dual Core,BLE,Wi-Fi; \u003cbr\u003e\nFlash: 4MB; \u003cbr\u003e\nInterface: 1x IR-TX,1x Function Button,1x Reset Button; \u003cbr\u003e\nPinOut: G21\/G25\/5V\/GND, 3V3\/G22\/G19\/G23\/G33; \u003cbr\u003e\nRGB LED: SK6812; \u003cbr\u003e\nSpeaker: 0.5W\/NS4168 I2S; \u003cbr\u003e\nMicphone: SPM1423 PDM; \u003cbr\u003e\nnet weight: 5g; \u003cbr\u003e\nGross weight: 10g; \u003cbr\u003e\nProduct Size: 24*24*17mm; \u003cbr\u003e\nPackage Size: 63*63*12mm; ; \u003cbr\u003e\nCase Material: Plastic ( PC ); \u003cbr\u003e\nNote: G19 \/ G22 \/ G23 \/ G33 has been defined, please do not reuse the above pins, otherwise ATOM ECH will be damaged. \u003cbr\u003e\n \u003cbr\u003e\nPeripherals Pin Map: \u003cbr\u003e\nDataOut BCLK DataIn LRCK RGB Btn: \u003cbr\u003e\nG22 G19 G23 G33 G27 G39: \u003cbr\u003e\n \u003cbr\u003e\nUsage: \u003cbr\u003e\nThe factory default firmware is Bluetooth 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 Bluetooth device is established, the LED will turn green. At this time, the sound can be output through atom ech. 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 Lexin.
