Cowin Lora Eriya Don OBJEX Link S3LW yana haɗa Wi-Fi, Bluetooth da LoRa akan allon ci gaban IoT

Na'urorin Intanet na Abubuwa (IoT) suna da babban buƙatun wuta. Misali, suna iya buƙatar tattara makamashi daga hasken rana yayin da suke amfani da ƙarancin wutar lantarki gwargwadon iyawa, ko kuma suna iya buƙatar sarrafa manyan kayan wuta. Injiniya OBJEX na Italiya Salvatore Raccardi ya magance waɗannan buƙatun tare da hukumar haɓaka OBJEX Link S3LW IoT. Na'urar tana amfani da tsarin S3LW wanda OBJEX ya haɓaka kuma yana da ikon sadarwa ta hanyar Wi-Fi, Bluetooth 5, LoRa da LoRaWAN ladabi. Har ila yau, yana ba da babbar mahimmanci ga ingantaccen amfani da makamashi.
OBJEX Link S3LW babban kwamiti ne na ci gaba na IoT wanda ya dogara da tsarin al'ada-kan-module (SoM). Tsarin S3LW yana ba da haɗin Wi-Fi, Bluetooth 5, LoRa da LoRaWAN haɗin gwiwa. Hukumar ci gaba tana da tashoshin GPIO guda 33 kuma tana goyan bayan mu'amalar microcontroller na yau da kullun kamar I2C, I2S, SPI, UART da USB. Masu haɗin STEMMA mai fil huɗu suna ba da damar PCBs samun damar haɓaka yanayin yanayin firikwensin firikwensin, masu kunnawa da nuni.
Lura. Raccardi ya haɓaka OBJEX Link shekaru da yawa da suka gabata. Samfurin yana da suna iri ɗaya da wannan sabon allon, amma akwai wasu bambance-bambance. Misali, tana amfani da ESP32-PICO-D4 microcontroller maimakon keɓewar SoM, amma bashi da aikin LoRa. Bugu da kari, yana da niyyar zama mafi ƙarancin hukumar da za a sake amfani da ita da kuma cikakken allo don haɓaka aikace-aikacen IoT.
OBJEX yana ba da samfuran S3 da S3LW. S3LW cikakken tsari ne wanda aka sanye shi da ESP32-S3FN8 microcontroller, RTC, SX1262 da da'irori masu alaƙa da wuta. ESP32 yana ba da damar Wi-Fi da Bluetooth, yayin da S3 ke goyan bayan dacewa da LoRa da LoRaWAN. Tsarin S3 bai ƙunshi kayan aikin LoRa ba, amma yana da wasu tubalan a cikin S3LW.
OBJEX Link S3LW yana nuna matakan da OBJEX ke ɗauka don cimma matsakaicin tanadin makamashi tare da keɓantattun kayayyaki. Na farko, rediyon LoRa yana da na'ura mai sarrafa wutar lantarki na musamman na layi wanda ke ba ku damar kashe rediyo gaba ɗaya lokacin da ba a buƙatar aikin LoRa. Na gaba ya zo da kulle wutar lantarki, wanda gaba daya ya kashe sauran kayan aikin module. Wannan latch ɗin baya maye gurbin yanayin barci mai zurfi na ESP32, amma ya cika shi.
Tun da S3LW yana da rediyo biyu masu aiki akan mitoci daban-daban, akwai hanyoyin eriya guda biyu. ESP32 guntu ce ta eriya wacce ke haɗa zuwa 2.4 GHz Wi-Fi da makada na Bluetooth. S3LW yana da mai haɗin U.Fl 50 ohm don eriyar LoRA ta waje. Rediyo yana aiki a cikin kewayon mitar daga 862 MHz zuwa 928 MHz.
Wutar OBJEX Link S3LW na iya fitowa daga tashar jiragen ruwa da ke goyan bayan isar da wutar lantarki ta USB-C (PD) ko kuma daga madaidaicin tasha da aka haɗa da Vbus iri ɗaya kamar mai haɗin USB-C. Ta hanyar samar da wutar lantarki, hukumar tana da damar zuwa 20 Volts, 5 Amps. Wurin da aka gina a cikin DC-DC Converter yana saukar da ƙarfin lantarki har zuwa 5V kuma yana samar da na yanzu har zuwa 2A zuwa abubuwan haɗin da aka haɗa.
Hukumar (da SoM) sun dace da yanayin shirye-shirye iri-iri, yana sa ya dace da kusan kowane ci gaba na aiki. Misali, yana goyan bayan Espressif ESP-IDF, Arduino IDE, PlatformIO, MicroPython da Rust.
Goyan bayan Cowin zuwa cusotm Wi-Fi, Bluetooth, LoRa, eriya ta ciki na IoT, da kuma samar da cikakken rahoton gwaji ciki har da VSWR, Gain, Inganci da Tsarin Radiation na 3D, da fatan za a tuntuɓe mu idan kuna da wata buƙata game da eriyar wayar hannu ta RF, eriyar Bluetooth WiFi, CAT-M Eriya, eriya LORA, IOT Eriya.
