Description
ESP32: Dual-Core WiFi/BLE Powerhouse for Connected Applications
The ESP32 is a feature‑rich, low‑power microcontroller that integrates a dual‑core Xtensa LX6 CPU with built‑in Wi‑Fi (802.11b/g/n) and Bluetooth LE 5.0. With up to 520 KB of SRAM and 448 KB of embedded flash, it delivers robust performance for demanding embedded applications while keeping power consumption down thanks to deep‑sleep and power‑management modes.
Its compact ESP‑12E/ESP‑01S board variants provide 34 programmable GPIOs, 18‑bit ADC, 2 × DAC, I²C, SPI, UART, SDIO, PWM, and capacitive touch, making the ESP32 a universal platform for sensors, actuators, and industrial control. The board is natively supported by Arduino, ESP‑IDF, and MicroPython, accelerating product development from prototypes to production.
