ماژول ESP32-WROOM-32

معرفی

 ESP32-WROOM-32D دارای بلوتوث و وای فای نسل تکامل یافته ESP8266 است که بارزترین تفاوت آن بلوتوث داخلی آن و دو هسته با فرکانس 80 تا 240 مگاهرتز است. دارای هسته وای فای 2.4 گیگاهرتز و بلوتوث داخلی تولید شده با تکنولوژی 40 نانومتری شرکت TSMC است. این برد وای فای دارای بهترین عملکرد در مصرف انرژی است.

از سری رابط هایی که این ماژول پشتیبانی می کند می توان به SD card, UART, SPI, SDIO, I2C, LED PWM, Motor PWM, I2S, IR, GPIO, capacitive touch sensor, ADC, DAC اشاره کرد. بر روی خود ماژول سنسور اثر هال و سنسور دما نیز تعبیه شده است. ماژول قدرتمند ESP-WROOM-32 با وجود بلوتوث، وایفای داخلی و هسته ESP32 برای رنج وسیعی از کاربردها و اهداف اینترنت اشیاء نظیر شبکه کردن سنسورها، هوشمندسازی ساختمان و… ساخته شده است.

Introduction

ESP32-WROOM-32D and ESP32-WROOM-32U are powerful, generic Wi-Fi+BT+BLE MCU modules that target a wide variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice encoding, music streaming and MP3 decoding. ESP32-WROOM-32U is different from ESP32-WROOM-32D in that ESP32-WROOM-32U integrates a U.FL connector.

The chip embedded is designed to be scalable and adaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable from 80 MHz to 240 MHz. The chip also has a low-power co-processor that can be used instead of the CPU to save power while performing tasks that do not require much computing power, such as monitoring of peripherals. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPI, UART, I²S and I²C.
