Cowin Lora Antenna Ya OBJEX Link S3LW imaphatikiza Wi-Fi, Bluetooth ndi LoRa pa bolodi lachitukuko la IoT

Zida za Internet of Things (IoT) zili ndi mphamvu zambiri. Mwachitsanzo, angafunikire kutolera mphamvu kuchokera ku mapanelo adzuwa pomwe akugwiritsa ntchito magetsi ochepa momwe angathere, kapena angafunikire kuyang'anira mphamvu zambiri. Katswiri waku Italy wa OBJEX Salvatore Raccardi wathana ndi zosowazi ndi bolodi yachitukuko ya OBJEX Link S3LW IoT. Chipangizochi chimagwiritsa ntchito S3LW module yopangidwa ndi OBJEX ndipo imatha kulankhulana kudzera pa Wi-Fi, Bluetooth 5, LoRa ndi LoRaWAN protocol. Imatsindikanso kwambiri kugwiritsa ntchito mphamvu moyenera.
OBJEX Link S3LW ndi gulu lachitukuko la IoT lochita bwino kwambiri potengera makonda amtundu-on-module (SoM). Module ya S3LW imapereka kulumikizana kwa Wi-Fi, Bluetooth 5, LoRa ndi LoRaWAN. Bungwe lachitukuko lili ndi madoko 33 a GPIO ndipo limathandizira mawonekedwe a microcontroller monga I2C, I2S, SPI, UART ndi USB. Zolumikizira za STEMMA zokhala ndi pini zinayi zimalola ma PCB kuti azitha kugwiritsa ntchito zachilengedwe zokulirakulira za masensa, ma actuators ndi zowonetsera.
Zindikirani. Raccardi adapanga OBJEX Link zaka zingapo zapitazo. Mankhwalawa ali ndi dzina lofanana ndi bolodi latsopanoli, koma pali zosiyana. Mwachitsanzo, imagwiritsa ntchito microcontroller ya ESP32-PICO-D4 m'malo mwa SoM yodzipereka, koma ilibe ntchito ya LoRa. Kuphatikiza apo, ikufuna kukhala bolodi yaying'ono kwambiri yomwe ingagwiritsidwenso ntchito komanso bolodi yodzaza ndi ntchito za IoT.
OBJEX imapereka ma module a S3 ndi S3LW. S3LW ndi gawo lathunthu lomwe lili ndi ESP32-S3FN8 microcontroller, RTC, SX1262 ndi mabwalo okhudzana ndi mphamvu. ESP32 imapereka mphamvu za Wi-Fi ndi Bluetooth, pomwe S3 imathandizira kuyanjana kwa LoRa ndi LoRaWAN. S3 module ilibe LoRa hardware, koma ili ndi midadada ina mu S3LW.
OBJEX Link S3LW ikuwonetsa masitepe omwe OBJEX imatenga kuti apulumutse mphamvu zambiri ndi ma module ake odzipereka. Choyamba, wailesi ya LoRa ili ndi chowongolera chapadera chamagetsi chomwe chimakulolani kuti muzimitse wailesiyo ngati palibe ntchito ya LoRa. Kenako pamabwera loko yamagetsi, yomwe imalepheretsa zida zonse za module. Latch iyi silowa m'malo mwa ESP32's tulo tofa nato, koma imakwaniritsa.
Popeza S3LW ili ndi ma wayilesi awiri omwe akugwira ntchito pama frequency osiyanasiyana, pali njira ziwiri za tinyanga. ESP32 ndi chipangizo cha mlongoti chomwe chimalumikizana ndi 2.4 GHz Wi-Fi ndi mabandi a Bluetooth. S3LW ili ndi cholumikizira cha 50 ohm U.Fl cha mlongoti wakunja wa LoRA. Wailesi imagwira ntchito pafupipafupi kuchokera ku 862 MHz mpaka 928 MHz.
Mphamvu ya OBJEX Link S3LW imatha kubwera kuchokera padoko lomwe limathandizira USB-C Power Delivery (PD) kapena kuchokera pa screw terminal block yolumikizidwa ku Vbus yomweyo monga cholumikizira USB-C. Kupyolera mu mphamvu zamagetsi, bolodi ili ndi mwayi wa 20 Volts, 5 Amps. Chosinthira chomangidwa mkati cha DC-DC chimatsitsa ma voliyumu mpaka 5V ndikupereka pano mpaka 2A ku zotumphukira zolumikizidwa.
Bolodi (ndi SoM) imagwirizana ndi mitundu yosiyanasiyana yamapulogalamu, ndikupangitsa kuti ikhale yoyenera pamayendedwe aliwonse achitukuko. Mwachitsanzo, imathandizira Espressif ESP-IDF, Arduino IDE, PlatformIO, MicroPython ndi Dzimbiri.
Thandizo la Cowin ku cusotm Wi-Fi, Bluetooth, LoRa, IoT mlongoti wakunja wakunja, ndikupereka lipoti lathunthu loyesa kuphatikiza VSWR, Gain, Efficiency ndi 3D Radiation Pattern, chonde titumizireni ngati muli ndi pempho la RF cellular antenna, WiFi Bluetooth antenna, CAT-M Antenna, LORA Mlongoti, IOT Mlongoti.
