ESP32 is a powerful, low-cost microcontroller developed by Espressif Systems. It is widely used in IoT (Internet of Things) applications due to its Wi-Fi and Bluetooth capabilities, high processing power, and low power consumption.
Dual-core or single-core processor: Uses Xtensa LX6 or Xtensa LX7 (ESP32-S3) at up to 240 MHz.
Wi-Fi and Bluetooth: Supports Wi-Fi 802.11 b/g/n and Bluetooth 4.2/5.0 (BLE + Classic).
Low power consumption: Suitable for battery-operated projects with deep sleep modes.
Multiple GPIO pins: Supports ADC, DAC, I²C, SPI, UART, PWM, and Capacitive Touch.
Security features: Supports encryption, secure boot, and flash encryption.
Built-in peripherals: Includes an RTC, temperature sensor, Hall effect sensor, and more.
Large flash and RAM: Typically comes with 4 MB flash and 520 KB SRAM.
