Specifications (typical) MCU: ESP32 (dual-core 32-bit up to 240 MHz), 520 KB SRAM Wireless: 2.4 GHz Wi-Fi 802.11 b/g/n, Bluetooth v4.2 BR/EDR + BLE Flash: 4 MB USB–UART: CH340 (driver may be required) I/O: Up to ~30 usable GPIO (board pins: 38) with PWM , I²C , SPI , UART ADC/DAC/Touch: 12-bit ADC (up to 18 ch), 2× DAC , 10× capacitive touch Supply: 5 V via Micro-USB (or 5 V pin), on-board 3.3 V regulator Logic level: 3.3 V (do not feed 5 V into GPIO) Buttons: EN/RESET , BOOT/IO0 Connector: Micro-USB Dimensions: ~51 × 26 mm; 38-pin breadboard footprint المواصفات : المتحكم: ESP32 ثنائي النواة حتى 240 MHz، ذاكرة 520 KB SRAM لاسلكي: واي-فاي 2.4 GHz 802.11 b/g/n، بلوتوث v4.2 BLE الفلاش: 4 MB واجهة USB–UART: CH340 (قد يتطلب تعريفًا) المداخل/المخارج: حتى ~30 منفذ GPIO فعّال (عدد الأرجل 38) مع PWM و I²C و SPI و UART التحويلات: ADC بدقة 12-بت (حتى 18 قناة)، 2× DAC ، 10 لمس capacitive التغذية: 5 V عبر Micro-USB (أو رجل 5 V) مع منظم 3.3 V مدمج مستوى المنطق: 3.3 V (لا تُغذِّ GPIO بـ5 V) الأزرار: إعادة تشغيل EN/RESET و BOOT/IO0 المنفذ: Micro-USB الأبعاد: ~51 × 26 مم؛ تخطيط 38 سنًا مناسب للبريدبورد Compatibility & software Works with Arduino IDE , PlatformIO , ESP-IDF . Select “ESP32 Dev Module”. Install CH340 driver if the board isn’t detected. Supports OTA, LittleFS/SPIFFS, and common libraries (WiFiClient, BLE, MQTT, FastLED, etc.). متوافق مع Arduino IDE و PlatformIO و ESP-IDF . اختر “ESP32 Dev Module”. ثبّت تعريف CH340 إذا لم يتعرّف النظام على اللوحة. يدعم OTA وLittleFS/SPIFFS ومكتبات شائعة مثل WiFiClient وBLE وMQTT وFastLED. Power notes & tips Power from Micro-USB 5 V ; heavy peripherals should use their own supply with common ground. Some pins have boot-strapping functions (e.g., IO0 , IO2 , EN )—avoid pulling them to the wrong level on startup. For LEDs/servos, share GND and use level shifting if a device needs 5 V logic . غذِّ اللوحة من 5 V عبر Micro-USB ؛ الملحقات ذات الاستهلاك العالي تحتاج مزوّدًا منفصلًا مع أرضي مشترك. بعض الأرجل لها وظائف إقلاع ( IO0 , IO2 , EN ) — تجنّب سحبها لمستوى غير مناسب أثناء البدء. مع شرائط LED/سيرفو: اشترك في GND واستخدم مبدّل مستويات إذا تطلب الملحق منطق 5 V .

Description
ESP32-WROOM-32 is a powerful, generic Wi-Fi + Bluetooth + Bluetooth LE MCU module that targets 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. At the core of this module is the ESP32-D0WDQ6 chip*. 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 coprocessor 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. Supply voltage: 5 V – with microUSB Driver: CH340C Dimensions: 52 x 28mm Technical Specifications ESP32-WROOM-32 TECHNICAL Bandwidth 72 MHz Data Rate 150 Mbps Interface Ethernet, I2C, I2S, SPI, UART Max Frequency 2.484 GHz Max Operating Temperature 85 °C Max Supply Voltage 3.6 V Min Operating Temperature -40 °C Min Supply Voltage 3 V Nominal Supply Current 500 mA Number of ADC Channels 16 Number of GPIO 32 Documents CH340C Datasheet ESP32-WROOM-32
