19Overview
20--------
21
22ESP32-DevKitC V2 is a small-sized ESP32-based development board produced by `Espressif <https://espressif.com>`_. 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.

55Power Supply Options
56--------------------
57
58There are three mutually exclusive ways to provide power to the board:
59
60* Micro USB port, default power supply
61* 5V / GND header pins
62* 3V3 / GND header pins
63
64.. warning::
65
66    The power supply must be provided using **one and only one of the options above**, otherwise the board and/or the power supply source can be damaged.

69Start Application Development
70------------------------------
71
72Before powering up your ESP32-DevKitC V2, please make sure that the board is in good condition with no obvious signs of damage.
73
74After that, proceed to :doc:`../../get-started/index`, where Section :ref:`get-started-step-by-step` will quickly help you set up the development environment and then flash an example project onto your board.
