AtomS3R AI Chatbot Kit (8MB PSRAM)
Description AtomS3R-AI Chatbot is an AI voice development kit. The kit consists of two core parts: the controller and the voice base. The controller adopts AtomS3R, which is based on the ESP32-S3 chip. It provides a large memory combination of 8 MB Flash + 8 MB PSRAM. It also integrates a 9-axis IMU (BMI270 + BMM150), IR emission tube, and other rich peripherals. The voice base uses Atomic Echo Base, based on the ES8311 audio codec chip, capable of high-fidelity audio decoding and microphone and speaker driving. The kit supports integration with XiaoZhi Voice Assistant, OpenAI Voice Assistant, and Volcengine Voice Assistant, enabling real-time voice interaction, custom wake words, and low-latency recognition. Features Supports XiaoZhi Voice Assistant, OpenAI Voice Assistant, etc. AI voice recognition Edge-cloud collaboration and model management Integrated ESP32-S3 main controller 9-axis sensor system Edge AI inference 8 MB Flash and 8 MB PSRAM Supports infrared emission control Expandable pins and interfaces Full-duplex I2S voice 24-bit audio codec MEMS digital microphone Class D amplifier (8 Ω @ 1 W speaker) Development platforms: ESP-IDF PlatformIO Arduino UiFlow2 Includes 1 x AtomS3R 1 x Atomic Echo Base Applications Voice assistant Smart home Specifications Specification Parameter SoC ESP32-S3-PICO-1-N8R8, dual-core Xtensa LX7 @240 MHz, USB-OTG PSRAM 8 MB PSRAM FLASH 8 MB FLASH TFT Driver GC9107 Color IPS Resolution 128 × 128 6-axis attitude sensor(BMI270) Accuracy: 0.05% (acceleration), 0.05°/s (angular velocity)I2C address: 0x68 3-axis geomagnetic sensor(BMM150) Accuracy: 0.3 μTMounted on BMI270, magnetometer data obtained via Sensor Hub Infrared IR ∠180° emission distance: 12.46 m (unobstructed) Expansion Interfaces Bottom GPIO: G5/G6/G7/G8/G38/G39 and HY2.0-4P expansion port Audio Codec ES8311: 24-bit resolution, using I2S protocol MEMS Microphone MSM381A3729H9BPC, SNR: ≥65 dB Power Amplifier NS4150B: Class D power amplifier Speaker 2014 cavity speaker: 1 W @ 8 Ω Operating Temperature 0 ~ 40 °C Product Dimensions AtomS3R: 24.0 × 24.0 × 12.9 mmAtomic Echo Base: 24.0 × 24.0 × 14.14 mm Product Weight AtomS3R: 6.6 gAtomic Echo Base: 6.3 g Package Dimensions 120.0 × 65.0 × 16.0 mm Package Weight 21.6 g LEARN AND DOCUMENTS DOCUMENTS
