Extremely compact at just 24 x 24 x 17 mm, it can stream music by connecting—via the ESP32’s wireless functions—to a phone, tablet, etc., or play designated streaming media over Wi-Fi. To simplify voice usage, Atom Voice integrates an STT (speech-to-text) service. Flash the dedicated firmware to enable it and issue voice commands to perform diverse operations. You can also write your own code to connect to cloud platforms such as AWS or Google; using the built-in microphone and speaker, Atom Voice can provide AI capabilities for voice control, smart interaction, IoT, and more. An on-board RGB LED (SK6812) clearly indicates connection status. In addition to serving as a smart speaker, it retains the control abilities of the ATOM series—you can connect external devices through the GROVE port. An M2 screw hole on the back facilitates mounting. Note Pin Usage Precautions G19 / G22 / G23 / G33 have been predefined. Do not reuse these pins; otherwise the Atom Voice may be damaged. Playback Precautions To prevent damage to the Atom Vioice, avoid the following operations: Outputting a DC signal through the I2S channel Playing white noise for long periods Playing full-scale square-wave audio Features Compact and lightweight Built-in STT service ESP32-based, supporting A2DP and BLE 4.0 Wi-Fi protocol IEEE 802.11 b/g/n Integrated microphone and speaker RGB LED status indication GROVE expansion connector Audio recording and playback Independent programmable button Development platforms: Arduino, ESP-IDF / ADF Includes 1 x Atom Vioice Applications Specifications Specification Parameter SoC ESP32-PICO-D4, 240 MHz, Dual Core, Wi-Fi Flash 4 MB Interface 1 x IR-TX, 1 x Button, 1 x Reset Button PinOut G21/G25/5V/GND, 3V3/G22/G19/G23/G33 RGB LED SK6812 Speaker 0.8 W / NS4168 (I²S) Microphone SPM1423 (PDM) Enclosure Plastic (PC) Product Weight 5 g Gross Weight 10 g Product Size 24 x 24 x 17 mm Package Size 85 x 65 x 17 mm Pin Usage Precautions G19 / G22 / G23 / G33 have been predefined.
