Cowin Lora Antenna Kuri OBJEX Ihuza S3LW ihuza Wi-Fi, Bluetooth na LoRa ku kibaho cyiterambere cya IoT

Ibikoresho bya interineti yibintu (IoT) bifite imbaraga nyinshi zisabwa. Kurugero, barashobora gukenera gukusanya ingufu ziva mumirasire y'izuba mugihe bakoresha amashanyarazi make ashoboka, cyangwa barashobora gucunga imitwaro myinshi. Umutaliyani OBJEX injeniyeri Salvatore Raccardi yakemuye ibyo bikenewe hamwe na OBJEX Ihuza S3LW IoT. Igikoresho gikoresha module ya S3LW yakozwe na OBJEX kandi irashobora kuvugana hakoreshejwe Wi-Fi, Bluetooth 5, LoRa na LoRaWAN protocole. Ishimangira kandi cyane gukoresha neza ingufu.
OBJEX Ihuza S3LW nubuyobozi bukora cyane IoT yiterambere rishingiye kuri sisitemu yihariye-kuri-module (SoM). Module ya S3LW itanga Wi-Fi, Bluetooth 5, LoRa na LoRaWAN. Akanama gashinzwe iterambere gafite ibyambu 33 bya GPIO kandi gashyigikira interineti isanzwe ya microcontroller nka I2C, I2S, SPI, UART na USB. Ihuza rya bine-STEMMA ihuza PCBs kugera kubidukikije bigenda byiyongera bya ecosystem ya sensor, ikora na disikuru.
Icyitonderwa. Raccardi yateje imbere OBJEX Ihuriro hashize imyaka myinshi. Igicuruzwa gifite izina rimwe nki kibaho gishya, ariko hariho itandukaniro. Kurugero, ikoresha microcontroller ya ESP32-PICO-D4 aho gukoresha SoM yabigenewe, ariko ntabwo ifite imikorere ya LoRa. Mubyongeyeho, igamije kuba ikibaho gito gishobora gukoreshwa hamwe ninama yuzuye igaragara kubuyobozi bwa IoT.
OBJEX itanga modul ya S3 na S3LW. S3LW ni module yuzuye yuzuye ifite ibikoresho bya microcontroller ya ESP32-S3FN8, RTC, SX1262 hamwe numuyoboro ujyanye nimbaraga. ESP32 itanga ubushobozi bwa Wi-Fi na Bluetooth, mugihe S3 ishyigikira LoRa na LoRaWAN. Module ya S3 ntabwo irimo ibyuma bya LoRa, ariko ifite ibindi bice muri S3LW.
OBJEX Ihuza S3LW yerekana intambwe OBJEX itera kugirango igere ku kuzigama ingufu nyinshi hamwe na module yabigenewe. Ubwa mbere, radio LoRa ifite umurongo udasanzwe wumurongo wa voltage igufasha kuzimya burundu radio mugihe ibikorwa bya LoRa bidasabwa. Ibikurikira haza imbaraga zifunga, zihagarika rwose ibyuma bisigaye bya module. Iyi latch ntabwo isimbuza ESP32′s uburyo bwo gusinzira cyane, ahubwo irayuzuza.
Kubera ko S3LW ifite amaradiyo abiri akorera kuri radiyo zitandukanye, hariho inzira ebyiri za antenna. ESP32 ni antenna chip ihuza imirongo ya 2.4 GHz ya Wi-Fi na Bluetooth. S3LW ifite 50 ohm U.Fl ihuza antenne yo hanze ya LoRA. Radiyo ikorera mumurongo uri hagati ya 862 MHz na 928 MHz.
Imbaraga za OBJEX Ihuza S3LW irashobora kuva ku cyambu gishyigikira USB-C Amashanyarazi (PD) cyangwa kuva kumurongo wamashanyarazi uhuza Vbus imwe na USB-C ihuza. Binyuze mu gutanga amashanyarazi, ikibaho gifite amashanyarazi 20, Amps 5. Imashini yubatswe ya DC-DC iramanuka kuri voltage igera kuri 5V kandi itanga amashanyarazi agera kuri 2A kuri periferi ihujwe.
Ikibaho (na SoM) kirahujwe nuburyo butandukanye bwo gutangiza porogaramu, bigatuma bikwiranye niterambere ryakazi ryose. Kurugero, ishyigikira Espressif ESP-IDF, IDE ya Arduino, PlatformIO, MicroPython na Rust.
Inkunga ya Cowin kuri cusotm Wi-Fi, Bluetooth, LoRa, IoT antenna yo hanze yimbere, kandi itanga raporo yuzuye yo kwipimisha harimo VSWR, Inyungu, Imikorere na 3D Imirasire ya 3D, nyamuneka twandikire niba hari icyo usaba kuri antenne ya selile ya RF, antenne ya WiFi Bluetooth, CAT-M Antenna, Antenna ya LORA, Antenna ya IOT.
