M5STACK Atom EchoS3R Highly Integrated IoT Voice Interaction Controller
Deskripsyon
Atom EchoS3R is a highly integrated IoT voice interaction controller specially designed for intelligent voice control and human-computer interaction scenarios. At its core is the ESP32-S3-PICO-1-N8R8 main control chip, which supports Wi-Fi wireless communication and comes with built-in 8MB Flash and 8MB PSRAM, meeting the diverse application development needs and providing excellent performance and scalability. The audio system employs the ES8311 monaural codec, combined with a high-sensitivity MEMS microphone and NS4150B power amplifier, to achieve clear sound pickup and high-fidelity audio output, enhancing the voice recognition and interaction experience. It is suitable for voice interaction scenarios such as AI voice assistants and smart home control.

Quick Start
Preparasyon
- Vizite sit ofisyèl Arduino a websit la epi enstale Arduino IDE a https://www.arduino.cc/en/Main/Software
- Ajoute Manadjè Konsèy Administrasyon sa a URL pou File → Preferences → Additional Boards Manager URLs: https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json
- Open the Boards Manager, search for “ESP32”, and click install.
- After installation, select the board “ESP32S3 Dev Module”
- Configure the following options. USB CDC On Boot: “Enabled”, PSRAM：”OPI PSRAM”, USB Mode: “Hardware CDC and JTAG"
Scan Wi-Fi
Chwazi ansyen anamppwogram "Ex" laamples” → “WiFi” → “WiFiScan”, chwazi pò ki koresponn ak aparèy ou an, epi klike sou bouton konpile ak telechaje a nan kwen anwo gòch la. Apre telechajman an fini, ouvri Monitè Serial la pou view Enfòmasyon sou eskanè Wi-Fi.
BLE Scan
Chwazi ansyen anamppwogram "Ex" laamples” → “BLE” → ”Scan”, choose the port corresponding to your device, and click the compile and upload button in the top-left corner. After uploading is complete, open the Serial Monitor to view BLE scan information.
DEKLARASYON FCC
Nenpòt Chanjman oswa modifikasyon pati ki responsab pou konfòmite pa apwouve ekspreseman kapab anile otorite itilizatè a pou opere ekipman an. Aparèy sa a konfòm ak pati 15 Règ FCC yo. Operasyon an sijè a de kondisyon sa yo: (1) Aparèy sa a pa ka lakòz entèferans danjere, epi (2) aparèy sa a dwe aksepte nenpòt entèferans resevwa, enkli entèferans ki ka lakòz operasyon endezirab.
REMAK ENPÒTAN
Nòt: Yo te teste ekipman sa a epi yo jwenn li konfòme yo ak limit pou yon aparèy dijital Klas B, dapre pati 15 Règ FCC yo. Limit sa yo fèt pou bay pwoteksyon rezonab kont entèferans danjere nan yon enstalasyon rezidansyèl. Ekipman sa a jenere, itilize ak ka gaye enèji frekans radyo epi, si li pa enstale ak itilize an akò ak enstriksyon yo, ka lakòz entèferans danjere nan kominikasyon radyo. Sepandan, pa gen okenn garanti ke entèferans pa pral rive nan yon enstalasyon an patikilye. Si ekipman sa a lakòz entèferans danjere nan resepsyon radyo oswa televizyon, sa ki ka detèmine pa fèmen ekipman an epi limen, itilizatè a ankouraje pou eseye korije entèferans lan pa youn oswa plis nan mezi sa yo:
- Reoryantasyon oswa deplase antèn k ap resevwa a.
- Ogmante separasyon ki genyen ant ekipman ak reseptè a.
- Konekte ekipman an nan yon priz sou yon sikwi diferan de sa a ki reseptè a konekte.
- Konsilte konsesyonè a oswa yon teknisyen radyo/televizyon ki gen eksperyans pou èd.
Yo evalye aparèy la pou satisfè egzijans jeneral ekspoze RF yo. Aparèy la ka itilize nan kondisyon ekspoze pòtab san restriksyon.
