ESP32-DevKitC V2 Getting Started Guide (CMake)¶
This user guide shows how to get started with ESP32-DevKitC development board.
What You Need¶
1 × USB A / micro USB B cable
1 × PC loaded with Windows, Linux or Mac OS
If you want to start using this board right now, go directly to Section Start Application Development.
Overview¶
ESP32-DevKitC 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 connect these pins to peripherals as needed. Standard headers also make development easy and convenient when using a breadboard.
Functional Description¶
The following list and figure below describe key components, interfaces and controls of ESP32-DevKitC board.
- ESP-WROOM-32
Standard ESP-WROOM-32 module soldered to the ESP32-DevKitC board.
- EN
Reset button: pressing this button resets the system.
- 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.
- USB
USB interface. It functions as the power supply for the board and the communication interface between PC and ESP-WROOM-32.
- I/O

Power Supply Options¶
There following options are available to provide power supply to this board:
Micro USB port, this is default power supply connection
5V / GND header pins
3V3 / GND header pins
Warning
Above options are mutually exclusive, i.e. the power supply may be provided using only one of the above options. Attempt to power the board using more than one connection at a time may damage the board and/or the power supply source.
Start Application Development¶
Before powering up the ESP32-DevKitC, please make sure that the board has been received in good condition with no obvious signs of damage.
To start development of applications, proceed to Section Get Started (CMake), that will walk you through the Installation Step by Step.
