The ESP32 chip will be the heart of most of the projects we are going to build in the near future, because it offers everything we need in one low cost solution! On the board, except from the ESP32 chip, there is also a 3.3V regulator because the chip uses 3.3V logic levels, a CP2102 USB to serial driver, 2 tiny push buttons and 2 LEDs, a RED led which indicates that the board is receiving power and a BLUE led which is connected to digital pin 2. The board offers 30 pins to use in our projects. Let’s now take a look at the heart of the board the ESP32 chip.
As you can see, this chip is Dual Core! It offers two 32Bit Processing Units. One is responsible for the WiFi connectivity and the other one is available for executing our code! The typical frequency of the CPU cores is 160MHz which is double than the operating frequency of the ESP8266. The chip also offers WiFi and Bluetooth connectivity, 512KBs of RAM memory, up to 16MBs of flash memory, 36 GPIO pins, SPI, I2C, UART, I2S busses, up to 18 12Bit ADCs, 2 8Bit DAC, hardware encryption cores, temperature sensor, touch sensor, a Hall sensor and many more things.
