M5STACK Atom EchoS3R Yophatikizidwa Kwambiri ndi IoT Voice Interaction Controller
Kufotokozera
Atom EchoS3R ndi chowongolera cholumikizira mawu cha IoT chopangidwa mwaluso kuti chizitha kuwongolera mawu mwanzeru komanso momwe mumalumikizirana ndi makompyuta a anthu. Pakatikati pake pali chipangizo chachikulu chowongolera cha ESP32-S3-PICO-1-N8R8, chomwe chimathandizira kulumikizana popanda zingwe za Wi-Fi ndipo chimabwera ndi 8MB Flash ndi 8MB PSRAM yomangidwa, kukwaniritsa zosowa zosiyanasiyana zachitukuko cha mapulogalamu ndikupereka magwiridwe antchito abwino kwambiri komanso scalability. Makina omvera amagwiritsa ntchito ES8311 monaural codec, yophatikizidwa ndi maikolofoni ya MEMS yamphamvu komanso mphamvu ya NS4150B. amplifier, kuti mukwaniritse mawu omveka bwino komanso mawu odalirika kwambiri, kupititsa patsogolo kuzindikira kwamawu komanso kulumikizana. Ndiwoyenera kuyanjana ndi mawu monga othandizira mawu a AI komanso kuwongolera kwanzeru kunyumba.

Yambani Mwamsanga
Kukonzekera
- Pitani ku Arduino yovomerezeka webtsamba ndikuyika Arduino IDE https://www.arduino.cc/en/Main/Software
- Onjezani Board Manager wotsatira URL ku 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”
Jambulani Wi-Fi
Sankhani wakaleampndi pulogalamu "Examples” → “WiFi” → “WiFiScan”, sankhani doko lolingana ndi chipangizo chanu, ndikudina batani lophatikiza ndi kukweza pamwamba kumanzere. Mukamaliza kutsitsa, tsegulani seri Monitor kuti view Zambiri za scan ya Wi-Fi.
BLE Scan
Sankhani wakaleampndi pulogalamu "Examples” → “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 Zambiri za scan ya BLE.
NKHANI YA FCC
Kusintha kulikonse kapena kusintha komwe sikunavomerezedwe ndi gulu lomwe limayang'anira kutsata kungathe kulepheretsa wogwiritsa ntchito kugwiritsa ntchito zidazo. Chipangizochi chikugwirizana ndi gawo 15 la Malamulo a FCC. Kugwira ntchito kumadalira zinthu ziwiri izi: (1) Chipangizochi sichingabweretse kusokoneza koopsa, ndipo (2) chipangizochi chiyenera kuvomereza kusokoneza kulikonse komwe kumalandira, kuphatikizapo kusokoneza komwe kungayambitse ntchito yosayenera.
MFUNDO YOFUNIKA
Zindikirani: Zipangizozi zayesedwa ndipo zapezeka kuti zikugwirizana ndi malire a chipangizo cha digito cha Gulu B, motsatira gawo 15 la Malamulo a FCC. Malire awa adapangidwa kuti apereke chitetezo chokwanira ku kusokoneza koyipa pakukhazikitsa nyumba. Chipangizochi chimapanga, chimagwiritsa ntchito komanso chimatha kuwunikira mphamvu zamawayilesi ndipo, ngati sichinayikidwe ndikugwiritsidwa ntchito motsatira malangizo, chikhoza kuyambitsa kusokoneza kwa mawayilesi. Komabe, palibe chitsimikizo kuti kusokoneza sikudzachitika mu unsembe winawake. Ngati chida ichi chikuyambitsa kusokoneza koyipa kwa wailesi kapena kulandila wailesi yakanema, komwe kungadziwike ndikuzimitsa ndi kuyatsa zida, wogwiritsa ntchitoyo akulimbikitsidwa kuyesa kusokoneza ndi chimodzi kapena zingapo mwa izi:
- Yankhanitsaninso kapena sinthani mlongoti wolandira.
- Wonjezerani kulekana pakati pa zida ndi wolandila.
- Lumikizani zida ndi potuluka padera losiyana ndi lomwe wolandila amalumikizidwa.
- Funsani wogulitsa kapena wodziwa ntchito pa wailesi/TV kuti akuthandizeni.
Chipangizochi chawunikidwa kuti chikwaniritse zofunikira zonse za RF. Chipangizochi chitha kugwiritsidwa ntchito powonekera popanda kuletsa.
