ESP32 is a series of low-cost, low-power systems on a chip microcontroller with integrated Wi-Fi and dual-mode Bluetooth. It can perform as a complete standalone system or as a slave device to a host MCU, reducing communication stack overhead on the main application processor. ESP32 can interface with other systems to provide Wi-Fi and Bluetooth functionality through its SPI / SDIO or I2C / UART interfaces.

Specifications of ESP32

  • The ESP32 is dual-core, which means it has 2 processors.
  • It has Wi-Fi and Bluetooth built-in.
  • It runs 32-bit programs.
  • The clock frequency can go up to 240MHz and it has 512 kB RAM.
  • This particular board has 30 or 36 pins, 15 in each row.
  • It also has a wide variety of peripherals available, like capacitive touch, ADCs, DACs, UART, SPI, I2C, and much more.
  • It comes with a built-in hall effect sensor and a built-in temperature sensor.
