Features and Details
- Microcontroller: ESP-WROOM-32
- Processor: Xtensa dual-core 32-bit LX6
- Clock Speed: 240 MHz
- RAM: 520 KB SRAM, 448 KB ROM, 16 KB SRAM in RTC
- Flash Memory: 4 MB
- WiFi: 802.11b/g/n
- Bluetooth: V4.2
- GPIOs: 25
- Antenna: On-board PCB antenna
- Programming Port: Micro USB
- USB to UART: CP2102
- Dimensions: 50 × 29 mm (±2)
- HSPI and VSPI both can be used for SPI interfaces, where VSPI pins are commonly used in standard libraries.
- All GPIOs (except input-only) can be used as PWM pins.
- ADC2 pins can’t be used when WiFi is enabled.
- All DACs have 8-bit resolution.
- ESP32 has two I2C buses but no dedicated pins. It allows for flexible pin assignment. (GPIO21 and GPIO22 are commonly used.)
- Installing the ESP32 Board in the Arduino IDE
