M5STACK Atom EchoS3R Selaoli sa Tšebelisano ea Lentsoe la IoT Haholo
Tlhaloso
Atom EchoS3R ke taolo ea tšebelisano ea lentsoe ea IoT e kopaneng haholo e etselitsoeng ka ho khetheha taolo e bohlale ea lentsoe le maemo a tšebelisano ea khomphutha ea motho. Motheong oa eona ke chip ea taolo ea mantlha ea ESP32-S3-PICO-1-N8R8, e ts'ehetsang puisano e se nang mohala ea Wi-Fi mme e tla le 8MB Flash le 8MB PSRAM e hahelletsoeng, e fihlelang litlhoko tse fapaneng tsa nts'etsopele ea ts'ebeliso le ho fana ka ts'ebetso e ntle haholo le sekhahla. Sistimi ea molumo e sebelisa ES8311 monaural codec, e kopantsoeng le maekerofounu e phahameng ea MEMS le matla a NS4150B. amplifier, ho fumana molumo o hlakileng oa molumo le molumo o phahameng oa molumo, ho ntlafatsa temoho ea lentsoe le boiphihlelo ba tšebelisano. E loketse maemo a tšebelisano ea lentsoe joalo ka bathusi ba lentsoe la AI le taolo e bohlale ea lapeng.

Tokisetso
- Etela Arduino ea molao websebaka mme o kenye Arduino IDE https://www.arduino.cc/en/Main/Software
- Kenya Motsamaisi oa Boto ea latelang URL ho File → Likhetho → Motsamaisi oa Liboto tse Eketsehileng URLs: https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json
- Bula Motsamaisi oa Boto, batla "ESP32", ebe o tobetsa kenya.
- Kamora ho kenya, khetha boto "ESP32S3 Dev Module"
- Lokisa likhetho tse latelang. USB CDC ho Boot: "E nolofalitsoe", PSRAM:" OPI PSRAM", Mokhoa oa USB: "Hardware CDC le JTAG”
Wi-Fi Scan
Khetha mohlalaample lenaneo “Examples” → “WiFi” → “WiFiScan”, khetha boema-kepe bo tsamaellanang le sesebelisoa sa hau, ebe o tobetsa konopo ea bokella le ho kenya k'honeng e kaholimo ho le letšehali. Kamora ho kenya ho phethehile, bula Serial Monitor ho view Lintlha tsa tlhahlobo ea Wi-Fi.
BLE Scan
Khetha mohlalaample lenaneo “Examples” → “BLE” → “Scan”, khetha boema-kepe bo tsamaellanang le sesebelisoa sa hau, ebe o tobetsa konopo ea bokella le ho kenya sekhutlong se kaholimo ho le letšehali. Kamora ho kenya ho phethehile, bula Serial Monitor ho view Lintlha tsa tlhahlobo ea BLE.
TLHOKOMELO FCC
Liphetoho life kapa life tse sa amoheloeng ka kotloloho ke mokha o ikarabellang bakeng sa tumellano li ka hlakola matla a mosebelisi a ho sebelisa sesebelisoa. Sesebelisoa sena se lumellana le karolo ea 15 ea Melao ea FCC. Ts'ebetso e ipapisitse le maemo a mabeli a latelang: (1) Sesebelisoa sena se kanna sa se ke sa baka tšitiso e kotsi, 'me (2) sesebelisoa sena se tlameha ho amohela tšitiso efe kapa efe e amohetsoeng, ho kenyelletsa le tšitiso e ka bakang ts'ebetso e sa batleheng.
BOHLOKOA HLOKO
Hlokomela: Thepa ena e lekoa 'me e fumanoe e lumellana le meeli ea sesebelisoa sa digital sa Sehlopha sa B, ho latela karolo ea 15 ea Melao ea FCC. Meeli ena e etselitsoe ho fana ka tšireletso e utloahalang khahlanong le tšitiso e kotsi mohahong oa bolulo. Thepa ena e hlahisa, e sebelisa le ho khantša matla a maqhubu a seea-le-moea, 'me haeba e sa kengoa le ho sebelisoa ho latela litaelo, e ka baka tšitiso e kotsi likhokahanong tsa radio. Leha ho le joalo, ha ho na tiiso ea hore tšitiso e ke ke ea etsahala setsing se itseng. Haeba sesebelisoa sena se baka tšitiso e kotsi ea seea-le-moea kapa kamohelo ea thelevishene, e ka lekanyetsoang ka ho tima le ho tima sesebelisoa, mosebelisi o khothalletsoa ho leka ho lokisa tšitiso ka e le 'ngoe kapa tse ling tsa mehato e latelang:
- Sheba hape kapa o suthise lenakana le amohelang sebakeng se seng.
- Eketsa karohano pakeng tsa thepa le moamoheli.
- Hokela lisebelisoa le seketsoaneng sa potoloho se fapaneng le seo moamoheli a hokahaneng le sona.
- Ikopanye le morekisi kapa setsebi sa radio/TV se nang le boiphihlelo bakeng sa thuso.
Sesebediswa sena se hlahlobilwe ho fihlela ditlhoko tse akaretsang tsa kgahlamelo ya RF. Sesebelisoa se ka sebelisoa maemong a ponts'o a nkehang ntle le thibelo.
