Cowin Lora Antenna ee loogu talagalay OBJEX Link S3LW waxay ku daraysaa Wi-Fi, Bluetooth iyo LoRa guddiga horumarinta IoT

Aaladaha Internetka ee Waxyaabaha (IoT) waxay leeyihiin shuruudo awood sare leh. Tusaale ahaan, waxa laga yaabaa inay u baahdaan inay tamar ka soo ururiyaan baallayaasha cadceedda iyagoo isticmaalaya koronto yar intii suurtogal ah, ama waxay u baahnaan karaan inay maareeyaan culayska tamarta sare leh. Injineer talyaani OBJEX Salvatore Raccardi ayaa baahiyahan wax ka qabtay guddiga horumarinta OBJEX Link S3LW IoT. Qalabku wuxuu isticmaalayaa moduleka S3LW ee uu sameeyay OBJEX wuxuuna awood u leeyahay inuu ku xidhiidho Wi-Fi, Bluetooth 5, LoRa iyo borotokoolka LoRaWAN. Waxa kale oo ay xooga saartaa isticmaalka hufan ee tamarta.
OBJEX Link S3LW waa guddi horumarineed IoT-waxqabad sare leh oo ku salaysan nidaamka-ku-salaysan-module-ka (SoM). Qaybta S3LW waxay bixisaa isku xidhka Wi-Fi, Bluetooth 5, LoRa iyo LoRaWAN. Guddiga horumarintu waxa uu leeyahay 33 dekedood oo GPIO ah waxana ay taageertaa is dhex galka microcontroller-ka caadiga ah sida I2C, I2S, SPI, UART iyo USB. Xidhiidhiyayaasha STEMMA ee afar-pin ah ayaa u oggolaanaya PCB-yada inay galaan nidaamka deegaanka ee sii kordhaya ee dareemayaasha, hawl-wadeennada iyo bandhigyada.
Ogow. Raccardi wuxuu horumariyay OBJEX Link dhowr sano ka hor. Alaabtu waxay leedahay magac la mid ah guddigan cusub, laakiin waxaa jira kala duwanaansho. Tusaale ahaan, waxay isticmaashaa ESP32-PICO-D4 microcontroller halkii ay ka isticmaali lahayd SoM-ga u heellan, laakiin ma laha shaqeyn LoRa. Intaa waxaa dheer, waxay higsaneysaa inay noqoto guddiga ugu yar ee dib loo isticmaali karo iyo guddi si buuxda u leh horumarinta codsiga IoT.
OBJEX waxay bixisaa S3 iyo S3LW modules. S3LW waa module si buuxda u qalabaysan ESP32-S3FN8 microcontroller, RTC, SX1262 iyo wareegyada la xiriira awoodda. ESP32 waxay bixisaa Wi-Fi iyo awoodaha Bluetooth, halka S3 ay taageerto waafaqid LoRa iyo LoRaWAN. Module-ka S3 kuma jiro qalabka LoRa, laakiin waxa uu leeyahay qaybo kale oo S3LW ah.
OBJEX Link S3LW waxa uu muujinayaa tillaabooyinka OBJEX ay qaado si loo gaadho kaydka tamarta ugu badan iyada oo la adeegsanayo cutubyadeeda u heellan. Marka hore, raadiyaha LoRa wuxuu leeyahay nidaamiye danab toosan oo toos ah kaas oo kuu ogolaanaya inaad gabi ahaanba damiso raadiyaha marka hawlgalka LoRa aan loo baahnayn. Waxaa ku xiga qufulka korontadu, kaas oo gebi ahaanba curyaamiya inta ka hartay qalabka moduleka. Xidhmadani ma beddesho habka hurdo qoto dheer ee ESP32, laakiin taa beddelkeeda.
Maadaama S3LW uu leeyahay laba raadiye oo ku shaqeeya mawjadaha kala duwan, waxaa jira laba waddo oo anteeno ah. ESP32 waa chip anteeno ah oo ku xidha 2.4 GHz Wi-Fi iyo xadhkaha Bluetooth. S3LW waxay leedahay isku xidhaha 50 ohm U.Fl anteenada LoRA ee dibadda ah. Raadiyaha wuxuu ku shaqeeyaa inta jeer ee u dhexeysa 862 MHz ilaa 928 MHz.
Awoodda OBJEX Link S3LW waxay ka iman kartaa deked taageerta USB-C Power Delivery (PD) ama ka soo xidhidhiyaha teerminalka ee ku xidhan isla Vbus sida xidhiidhiyaha USB-C. Iyada oo loo marayo sahayda korantada, guddigu wuxuu heli karaa 20 Volts, 5 Amps. Beddelaha ku dhex jira DC-DC wuxuu hoos u dhigaa danabka ilaa 5V wuxuuna sahayda hadda ilaa 2A meelaha ku xiran.
Guddiga (iyo SoM) waxay la jaan qaadayaan deegaan barnaamijyo kala duwan, taasoo ka dhigaysa mid ku habboon ku dhawaad ​​shaqo kasta oo horumarineed. Tusaale ahaan, waxay taageertaa Espressif ESP-IDF, Arduino IDE, PlatformIO, MicroPython iyo Rust.
Taageerada Cowin ee ku habboon Wi-Fi, Bluetooth, LoRa, anteenada gudaha IoT, oo bixi warbixin tijaabo ah oo dhammaystiran oo ay ku jiraan VSWR, Gain, Hufnaanta iyo Habka Shucaaca 3D, fadlan nala soo xiriir haddii aad wax codsi ah ka qabto anteenada gacanta ee RF, anteenada Bluetooth ee WiFi, CAT-M anteeno, anteeno LORA, IOT anteeno.
