Antenna Cowin Lora Maka OBJEX Link S3LW jikọtara Wi-Fi, Bluetooth na LoRa na bọọdụ mmepe IoT.

Ngwa Ịntanetị nke Ihe (IoT) nwere nnukwu ike chọrọ. Dịka ọmụmaatụ, ọ nwere ike ịdị ha mkpa ịnakọta ume site na oghere anyanwụ mgbe ha na-eji obere ọkụ eletrik dị ka o kwere mee, ma ọ bụ ha nwere ike ijikwa nnukwu ike. Onye injinia OBJEX Italy Salvatore Raccardi ejirila bọọdụ mmepe OBJEX Link S3LW IoT lebara mkpa ndị a anya. Ngwaọrụ ahụ na-eji modul S3LW nke OBJEX mepụtara ma nwee ike ịkparịta ụka site na Wi-Fi, Bluetooth 5, LoRa na LoRaWAN protocols. Ọ na-etinyekwa uche dị ukwuu n'iji ike eme ihe nke ọma.
OBJEX Link S3LW bụ bọọdụ mmepe IoT na-arụ ọrụ dị elu dabere na sistemụ-na-modul (SoM). Modul S3LW na-enye njikọ Wi-Fi, Bluetooth 5, LoRa na LoRaWAN. Ụlọ ọrụ mmepe ahụ nwere ọdụ ụgbọ mmiri 33 GPIO ma na-akwado ihu igwe microcontroller dị ka I2C, I2S, SPI, UART na USB. Njikọ STEMMA nwere pin-anọ na-enye PCB ohere ịnweta gburugburu ebe obibi na-agbasawanye mgbe niile nke sensọ, ndị na-eme ihe na ihe ngosi.
Rịba ama. Raccardi mepụtara njikọ OBJEX ọtụtụ afọ gara aga. Ngwaahịa nwere otu aha dị ka bọọdụ ọhụrụ a, mana enwere ụfọdụ ọdịiche. Dịka ọmụmaatụ, ọ na-eji ESP32-PICO-D4 microcontroller kama ịbụ SoM raara onwe ya nye, mana enweghị ọrụ LoRa. Na mgbakwunye, ọ na-achọ ịbụ bọọdụ a na-emegharịgharị nke kacha nta na bọọdụ nwere ngosipụta zuru oke maka mmepe ngwa IoT.
OBJEX na-enye modul S3 na S3LW. S3LW bụ modul zuru oke nke ejiri ESP32-S3FN8 microcontroller, RTC, SX1262 na sekit metụtara ike. ESP32 na-enye Wi-Fi na ikike Bluetooth, ebe S3 na-akwado ndakọrịta LoRa na LoRaWAN. Modul S3 enweghị ngwaike LoRa, mana o nwere ihe mgbochi ndị ọzọ na S3LW.
OBJEX Link S3LW na-egosiputa nzọụkwụ OBJEX na-ewe iji nweta oke nchekwa ike na modul ya raara onwe ya nye. Nke mbụ, redio LoRa nwere onye na-ahụ maka voltaji linear pụrụ iche nke na-enye gị ohere gbanyụọ redio kpamkpam mgbe arụ ọrụ LoRa adịghị mkpa. Na-esote mkpọchi ike, nke na-ewepụ kpamkpam ngwaike modul ndị ọzọ. Ihe mgbochi a anaghị edochi ọnọdụ ụra miri emi nke ESP32, kama ọ na-emeju ya.
Ebe S3LW nwere redio abụọ na-arụ ọrụ na ugboro dị iche iche, enwere ụzọ antenna abụọ. ESP32 bụ mgbawa antenna na-ejikọta na 2.4 GHz Wi-Fi na eriri Bluetooth. S3LW nwere njikọ U.Fl 50 ohm maka antenna LoRA dị n'èzí. Redio na-arụ ọrụ n'ogo ugboro site na 862 MHz ruo 928 MHz.
Ike maka OBJEX Link S3LW nwere ike isi na ọdụ ụgbọ mmiri na-akwado USB-C Power Delivery (PD) ma ọ bụ site na ngọngọ skru nke ejikọrọ na otu Vbus dị ka njikọ USB-C. Site na ọkụ eletrik, osisi ahụ nwere ike ịnweta 20 Volts, 5 Amps. Ihe ntụgharị DC-DC arụnyere n'ime na-agbada voltaji ruo 5V wee na-enye ugbu a ruo 2A na mpaghara ejikọrọ.
Ụlọ ọrụ ahụ (na SoM) dakọtara na mpaghara mmemme dị iche iche, na-eme ka ọ dị mma maka ihe fọrọ nke nta ka ọ bụrụ usoro mmepe ọ bụla. Dịka ọmụmaatụ, ọ na-akwado Espressif ESP-IDF, Arduino IDE, PlatformIO, MicroPython na Rust.
Nkwado Cowin na-akwado Wi-Fi, Bluetooth, LoRa, antenna mpụta nke IoT, ma nye akụkọ nnwale zuru oke gụnyere VSWR, Gain, arụmọrụ na ụkpụrụ Radiation 3D, biko kpọtụrụ anyị ma ọ bụrụ na ị nwere arịrịọ ọ bụla gbasara antenna cellular RF, eriri Bluetooth WiFi, Antenna CAT-M, antenna LORA, IOT Antenna.
