The Atom VoiceS3R Smart Speaker Dev Kit is a programmable IoT voice interaction controller built for intelligent voice control and human-computer interaction applications. Powered by the ESP32-S3-PICO-1-N8R8 dual-core Xtensa LX7 processor running up to 240MHz, this compact device measures just 0.94 x 0.94 x 0.66 inches and weighs only 0.33 ounces. It features 8MB Flash and 8MB PSRAM, providing ample memory for diverse application development. The audio system incorporates an ES8311 24-bit mono codec with I2S protocol, a high-sensitivity MEMS microphone with 65dB SNR, and an NS4150B Class D amplifier paired with an 8-ohm 1W speaker for clear voice pickup and high-fidelity audio output. Supporting 2.4GHz Wi-Fi wireless communication, the device includes an integrated infrared transmitter and expandable pins for enhanced functionality. Ideal for AI voice assistants, smart home control, and voice recognition projects, this development kit operates between 0 to 104 degrees Fahrenheit and requires DC 5V power input. The compact package includes everything needed to start building sophisticated voice interaction solutions.
