    The ESP32  can also interface with other systems to provide Wi-Fi and Bluetooth functionality through its SPI / SDIO or I2C / UART interfaces. it comes with a preloaded image of the AT command set, just like the ESP8266 did. If you want to waste 95% of this chip’s potential by using it as a glorified serial-to-WiFi modem, you are good to go!

    The operating voltage ranges from 2.3V to 3.6V. the recommended voltage is 3.3V, and its recommended output current is 500 mA or more.

    The ESP32 development board has pins, as follows:


     

    Power Pins There are two power pins viz. VIN pin & 3.3V pin. The VIN pin can be used to directly supply the ESP32 and its peripherals if you have a regulated 5V voltage source. The 3.3V pin is the output of an on-board voltage regulator. This pin can be used to supply power to external components.

    GND is a ground pin of the ESP32 development board.

    Arduino Pins are nothing but ESP32’s hardware I2C and SPI pins to hook up all sorts of sensors and peripherals in your project.

    GPIO Pins ESP32 development board has 25 GPIO pins which can be assigned to various functions programmatically. Each digital-enabled GPIO can be configured to internal pull-up or pull-down, or set to high impedance. When configured as an input, it can also be set to edge-trigger or level-trigger to generate CPU interrupts.

    ADC Channels The board integrates 12-bit SAR ADCs and supports measurements on 15 channels (analog enabled pins). Some of these pins can be used to build a programmable gain amplifier which is used for the measurement of small analog signals. The ESP32 is also designed to measure the voltages while operating in the sleep mode.

    DAC Channels The board features two 8-bit DAC channels to convert digital signals into true analog voltages. This dual DAC can drive other circuits.

    TouchPads The board offers 9 capacitive sensing GPIOs which detect capacitive variations introduced by the GPIO’s direct contact or close proximity with a finger or other objects.

    UART Pins ESP32 development board has 2 UART interfaces, i.e. UART0 and UART2, which provide asynchronous communication (RS232 and RS485) and IrDA support and communicate at up to 5 Mbps. UART provides hardware management of the CTS and RTS signals and software flow control (XON and XOFF) as well.

    SPI Pins SPI Pins ESP32 features three SPIs (SPI, HSPI, and VSPI) in slave and master modes. These SPIs also support the following general-purpose SPI features:

    • 4 timing modes of the SPI format transfer
    • Up to 80 MHz and the divided clocks of 80 MHz
    • Up to 64-Byte FIFO

    All SPIs can also be used to connect to the external Flash/SRAM and LCD.

    ~ PWM Pins The board has 25 channels (Nearly All GPIO pins) of PWM pins controlled by the Pulse Width Modulation (PWM) controller. The PWM output can be used for driving digital motors and LEDs. The controller consists of PWM timers and the PWM operator. Each timer provides timing in synchronous or independent form, and each PWM operator generates the waveform for one PWM channel.

    EN Pin is used to enabling ESP32. The chip is enabled when pulled HIGH. When pulled LOW the chip works at minimum power.
