Overview:

ESP32-DevKitC V4 is a small-sized ESP32-based development board produced by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-DevKitC V4 on a breadboard.

 Functional Description:

• ESP32-WROOM-32

ESP32-WROOM-32 module soldered to the ESP32-DevKitC V4 board. Optionally ESP32-WROOM-32D, ESP32-WROOM-32U or ESP32-SOLO-1 module may be soldered instead of the ESP32-WROOM-32.

• USB-UART Bridge

A single chip USB-UART bridge provides up to 3 Mbps transfers rates.

• Boot

Download button: holding down the Boot button and pressing the EN button initiates the firmware download mode. Then user can download firmware through the serial port.

• Micro USB Port

USB interface. It functions as the power supply for the board and the communication interface between PC and the ESP module.

• 5V Power On LED

This LED lights when the USB or an external 5V power supply is applied to the board. For details see schematic in Related Documents.

• EN 

Reset button: pressing this button resets the system.

• I/O

Most of the pins on the ESP module are broken out to the pin headers on the board. Users can program ESP32 to enable multiple functions such as PWM, ADC, DAC, I2C, I2S, SPI, etc.
