ESP32-PICO-KIT V3 Getting Started Guide
===============================================
:link_to_translation:`zh_CN:[中文]`

This guide shows how to get started with the ESP32-PICO-KIT V3 mini development board. For the description of other ESP32-PICO-KIT versions, please check :doc:`../hw-reference/index`.


What You Need
-------------

* ESP32-PICO-KIT V3 mini development board
* USB 2.0 A to Micro B cable
* Computer running Windows, Linux, or macOS

You can skip the introduction sections and go directly to Section `Start Application Development`_.


Overview
--------

ESP32-PICO-KIT V3 is an ESP32-based mini development board produced by `Espressif <https://espressif.com>`_. The core of this board is ESP32-PICO-D4 - a System-in-Package (SiP) module.

The development board features a USB-UART Bridge circuit, which allows developers to connect the board to a computer's USB port for flashing and debugging.

All the IO signals and system power on ESP32-PICO-D4 are led out to two rows of 20 x 0.1" header pads on both sides of the development board for easy access.


Functional Description
----------------------

The following figure and the table below describe the key components, interfaces, and controls of the ESP32-PICO-KIT V3 board.

Key Component       Description
==================  =================================================================================================================================
ESP32-PICO-D4       Standard ESP32-PICO-D4 module soldered to the ESP32-PICO-KIT V3 board. The complete ESP32 system on a chip (ESP32 SoC) has been integrated into the SiP module, requiring only an external antenna with LC matching network, decoupling capacitors, and a pull-up resistor for EN signals to function properly.

LDO                 5V-to-3.3V Low dropout voltage regulator (LDO).

USB-UART bridge     Single-chip USB-UART bridge provides up to 1 Mbps transfers rates.

Micro USB Port      USB interface. Power supply for the board as well as the communication interface between a computer and the board.

Power On LED        This red LED turns on when power is supplied to the board.

I/O                 All the pins on ESP32-PICO-D4 are broken out to pin headers. You can program ESP32 to enable multiple functions, such as PWM, ADC, DAC, I2C, I2S, SPI, etc.

BOOT Button         Download button. Holding down **Boot** and then pressing **EN** initiates Firmware Download mode for downloading firmware through the serial port.

EN Button           Reset button.

Start Application Development
-----------------------------

Before powering up your ESP32-PICO-KIT V3, please make sure that the board is in good condition with no obvious signs of damage.

After that, proceed to :doc:`../get-started-cmake/index`, where Section :ref:`get-started-step-by-step-cmake` will quickly help you set up the development environment and then flash an example project onto your board.

If you prefer using an older GNU Make build system, then proceed to respective :ref:`get-started-step-by-step` for the GNU Make.
