Amadivayisi e-inthanethi Yezinto (IoT) anezidingo zamandla aphezulu. Isibonelo, bangase badinge ukuqoqa amandla kuma-solar panel ngenkathi besebenzisa ugesi omncane ngangokunokwenzeka, noma bangase badinge ukuphatha imithwalo yamandla aphezulu. Unjiniyela wase-Italy we-OBJEX u-Salvatore Raccardi ubhekane nalezi zidingo ngebhodi lokuthuthukisa i-OBJEX Link S3LW IoT. Idivayisi isebenzisa imojuli ye-S3LW eyakhiwe yi-OBJEX futhi iyakwazi ukuxhumana nge-Wi-Fi, i-Bluetooth 5, i-LoRa ne-LoRaWAN protocol. Iphinde igcizelele kakhulu ukusetshenziswa kwamandla ngendlela efanele.
I-OBJEX Link S3LW iyibhodi lokuthuthukiswa kwe-IoT esebenza kahle ngokususelwe kuhlelo lwangokwezifiso lwe-module (SoM). Imojula ye-S3LW inikeza i-Wi-Fi, i-Bluetooth 5, i-LoRa ne-LoRaWAN yokuxhumana. Ibhodi lokuthuthukisa linamachweba we-GPIO angu-33 futhi lisekela ukuxhumana okujwayelekile kwe-microcontroller njenge-I2C, i-I2S, i-SPI, i-UART ne-USB. Izixhumi ze-STEMMA ezinamaphini amane zivumela ama-PCB ukuthi afinyelele i-ecosystem ehlala ikhula yezinzwa, ama-actuator nezibonisi.
Qaphela. U-Raccardi uthuthukise i-OBJEX Link eminyakeni embalwa edlule. Umkhiqizo unegama elifanayo naleli bhodi elisha, kodwa kukhona umehluko. Isibonelo, isebenzisa i-microcontroller ye-ESP32-PICO-D4 esikhundleni se-SoM ezinikele, kodwa ayinakho ukusebenza kwe-LoRa. Ngaphezu kwalokho, ihlose ukuba ibhodi elincane elisebenziseka kabusha kanye nebhodi elinezici ezigcwele zokuthuthukiswa kwesicelo se-IoT.
I-OBJEX ihlinzeka ngamamojula we-S3 kanye ne-S3LW. I-S3LW iyimojula enezici ezigcwele efakwe i-ESP32-S3FN8 microcontroller, i-RTC, i-SX1262 kanye namasekhethi ahlobene namandla. I-ESP32 inikeza amandla e-Wi-Fi nawe-Bluetooth, kuyilapho i-S3 isekela ukuhambisana kwe-LoRa ne-LoRaWAN. Imojula ye-S3 ayiqukethe ihadiwe ye-LoRa, kodwa inamanye amabhulokhi ku-S3LW.
I-OBJEX Link S3LW ibonisa izinyathelo ezithathwa yi-OBJEX ukuze kuzuzwe ukonga amandla okuphezulu ngamamojula ayo azinikele. Okokuqala, umsakazo we-LoRa unomlawuli we-voltage okhethekile ovumela ukuthi ucime ngokuphelele umsakazo lapho kungadingeki ukusebenza kwe-LoRa. Okulandelayo kuza ukhiye wamandla, okhubaza yonke ingxenye yezingxenyekazi zekhompuyutha ezisele. Le latch ayithathi indawo yemodi yokulala okujulile ye-ESP32, kodwa iyahambisana nayo.
Njengoba i-S3LW inemisakazo emibili esebenza kumafrikhwensi ahlukene, kunezindlela ezimbili zama-antenna. I-ESP32 iyi-antenna chip exhuma kumabhendi e-Wi-Fi angu-2.4 GHz kanye ne-Bluetooth. I-S3LW inesixhumi esingu-50 ohm U.Fl sothi lwe-LoRA lwangaphandle. Umsakazo usebenza kububanzi obusuka ku-862 MHz ukuya ku-928 MHz.
Amandla e-OBJEX Link S3LW angavela embobeni esekela i-USB-C Power Delivery (PD) noma asuke ku-screw terminal block exhunywe ku-Vbus efanayo nesixhumi se-USB-C. Ngokunikezwa kwamandla, ibhodi likwazi ukufinyelela ku-20 Volts, 5 Amps. Isiguquli esakhelwe ngaphakathi se-DC-DC sehlisa amandla kagesi aze afike ku-5V futhi sinikeze okwamanje kufika ku-2A kuma-peripheral axhunyiwe.
Ibhodi (kanye ne-SoM) iyahambisana nezinhlobonhlobo zezindawo zokuhlela, okuyenza ifaneleke cishe noma yikuphi ukugeleza komsebenzi wentuthuko. Isibonelo, isekela i-Espressif ESP-IDF, i-Arduino IDE, i-PlatformIO, i-MicroPython ne-Rust.
Ukusekelwa kwe-Cowin ku-cusotm Wi-Fi, i-Bluetooth, i-LoRa, i-antenna yangaphandle ye-IoT yangaphakathi, futhi inikeze umbiko ophelele wokuhlola ohlanganisa i-VSWR, Inzuzo, Ukusebenza kahle kanye nephethini ye-3D Radiation, sicela usithinte uma unesicelo mayelana ne-antenna yeselula ye-RF, i-WiFi Bluetooth antenna, I-CAT-M Antenna, i-antenna ye-LORA, i-IOT Antenna.
