Internet yezvinhu (IoT) zvishandiso zvine simba repamusoro zvinodiwa. Semuenzaniso, vangangoda kuunganidza simba kubva kune solar panels pavanenge vachishandisa magetsi mashoma sezvinobvira, kana kuti vangangoda kubata masimba makuru emagetsi. Italian OBJEX mainjiniya Salvatore Raccardi agadzirisa izvi zvinodiwa neOBJEX Link S3LW IoT yekuvandudza bhodhi. Chishandiso chinoshandisa S3LW module yakagadzirwa neOBJEX uye inokwanisa kutaurirana kuburikidza neWi-Fi, Bluetooth 5, LoRa uye LoRaWAN protocol. Inoisawo simbiso huru pakushandiswa zvakanaka kwesimba.
OBJEX Link S3LW ndeyepamusoro-inoshanda IoT yekuvandudza bhodhi yakavakirwa pane yakasarudzika system-on-module (SoM). Iyo S3LW module inopa Wi-Fi, Bluetooth 5, LoRa uye LoRaWAN yekubatanidza. Iyo bhodhi yekuvandudza ine makumi matatu nenhatu GPIO madoko uye inotsigira yakajairwa microcontroller interfaces seI2C, I2S, SPI, UART uye USB. Zvina-pini STEMMA zvibatanidza zvinobvumira maPCB kuti awane inogara ichiwedzera ecosystem yemasensor, actuators uye kuratidza.
Cherechedza. Raccardi akagadzira OBJEX Link makore akati wandei apfuura. Chigadzirwa chine zita rakafanana neiyi bhodhi idzva, asi pane zvimwe zvakasiyana. Semuenzaniso, inoshandisa ESP32-PICO-D4 microcontroller panzvimbo yeSoM yakatsaurirwa, asi haina LoRa kushanda. Pamusoro pezvo, ine chinangwa chekuve diki diki reusable board uye yakazara-inoratidzwa bhodhi yeIoT application yekuvandudza.
OBJEX inopa iyo S3 uye S3LW modules. S3LW is a full-featured module ane ESP32-S3FN8 microcontroller, RTC, SX1262 uye magetsi ane hukama. Iyo ESP32 inopa Wi-Fi uye Bluetooth kugona, nepo S3 inotsigira LoRa uye LoRaWAN kuenderana. Iyo S3 module haina LoRa hardware, asi ine mamwe mabhuroko muS3LW.
OBJEX Link S3LW inoratidza matanho anotorwa neOBJEX kuti uwane huwandu hwekuchengetedza simba nemamodule ayo akazvitsaurira. Chekutanga, iyo LoRa redhiyo ine yakakosha mutsara voltage regulator iyo inokutendera iwe kudzima zvachose redhiyo kana LoRa isingadiwe. Inotevera inouya simba rekuvhara, iro rinodzima zvachose mamwe ese emodule's hardware. Iyi latch haitsivi iyo ESP32's yakadzama yekurara modhi, asi kuti inozadzisa iyo.
Sezvo iyo S3LW iine maredhiyo maviri anoshanda pane akasiyana mafrequency, kune maviri antenna nzira. Iyo ESP32 iantenna chip inobatanidza kune 2.4 GHz Wi-Fi uye mabhendi eBluetooth. Iyo S3LW ine 50 ohm U.Fl yekubatanidza yekunze LoRA antenna. Radhiyo inoshanda mu frequency renji kubva pa862 MHz kusvika 928 MHz.
Simba reOBJEX Link S3LW rinogona kubva pachiteshi chinotsigira USB-C Power Delivery (PD) kana kubva kune screw terminal block yakabatana kune imwechete Vbus se USB-C yekubatanidza. Kuburikidza nemagetsi, bhodhi rinokwanisa kuwana makumi maviri Volts, 5 Amps. Iyo yakavakirwa-mukati DC-DC inoshandura inodzika pasi voltage kusvika ku5V uye inopa ikozvino kusvika ku2A kune yakabatana maperipheral.
Bhodhi (uye SoM) inoenderana nenzvimbo dzakasiyana siyana dzehurongwa, zvichiita kuti ive yakakodzera kune chero budiriro yekufambisa. Semuenzaniso, inotsigira Espressif ESP-IDF, Arduino IDE, PlatformIO, MicroPython uye Rust.
Cowin tsigiro yecusotm Wi-Fi, Bluetooth, LoRa, IoT yemukati yekunze antenna, uye inopa yakazara yekuyedza mushumo inosanganisira VSWR, Gain, Kubudirira uye 3D Radiation Pattern, ndapota taura nesu kana uine chero chikumbiro nezveRF cellular antenna, WiFi Bluetooth antenna, CAT-M Antenna, LORA antenna, IOT Antenna.
