ESP32-PICO-KIT V3 Getting Started Guide
=======================================
This user guide shows how to get started with the ESP32-PICO-KIT V3 mini development board. For description of other versions of the ESP32-PICO-KIT check :doc:`../hw-reference/index`.
What You Need
-------------
* 1 × ESP32-PICO-KIT V3 mini development board
* 1 × USB A / Micro USB B cable
* 1 × PC loaded with Windows, Linux or Mac OS
Overview
--------
ESP32-PICO-KIT V3 is a mini development board based on the ESP32-PICO-D4 SIP module produced by `Espressif <https://espressif.com>`_. All the IO signals and system power on ESP32-PICO-D4 are led out through two standard 20 pin x 0.1" pitch headers on both sides for easy interfacing. The development board integrates a USB-UART Bridge circuit, allowing the developers to connect the development board to a PC's USB port for downloads and debugging.
Functional Description
----------------------
The following list and figure below describe key components, interfaces and controls of ESP32-PICO-KIT V3 board.
ESP32-PICO-D4
Standard ESP32-PICO-D4 module soldered to the ESP32-PICO-KIT V3 board. The complete system of the ESP32 chip has been integrated into the SIP module, requiring only external antenna with LC matching network, decoupling capacitors and pull-up resistors for EN signals to function properly.
USB-UART Bridge
A single chip USB-UART bridge provides up to 1 Mbps transfers rates.
I/O
All the pins on ESP32-PICO-D4 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.
Micro USB Port
USB interface. It functions as the power supply for the board and the communication interface between PC and ESP32-PICO-KIT V3.
EN Button
Reset button; pressing this button resets the system.
BOOT 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.

Start Application Development
------------------------------
Before powering up the ESP32-PICO-KIT V3, 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 :doc:`index`, that will walk you through the following steps:
* :ref:`get-started-setup-toolchain` in your PC to develop applications for ESP32 in C language
* :ref:`get-started-connect` the module to the PC and verify if it is accessible
* :ref:`get-started-build-flash` an example application to the ESP32
* :ref:`get-started-build-monitor` instantly what the application is doing

For easy interfacing, all the IO signals and system power on ESP32-PICO-D4 are led out through two 20 x 0.1" pitch header pads on both sides of the development board. To make the ESP32-PICO-KIT V4 fit into mini breadboards, the header pads are populated with two 17 pin headers. Remaining 2 x 3 pads grouped on one side of the board besides the antenna are not populated. If required, the additional 2 x 3 pin headers may be soldered later by the user. The development board integrates a USB-UART Bridge circuit, allowing the developers to connect the board to a PC's USB port for downloads and debugging.
.. note::
The 2 x 3 pads not populated with pin headers are internally connected to the flash memory embedded in the ESP32-PICO-D4 SIP module. For more details see module's datasheet in :ref:`get-started-pico-kit-v4-related-documents`.

Previous Versions of ESP32 Modules and Boards
=============================================
This sections contains overview and links to documentation of previous version ESP32 Modules and Boards that have been replaced with newer versions or discontinued. It is maintained for convenience of users as several of these boards are still in use and some may still be available for purchase.
To see the latest development boards, please refer to section :ref:`esp-modules-and-boards`.

ESP32-PICO-KIT V3
-----------------
The first public release of Espressif's ESP32-PICO-D4 chip on a mini development board. The board has a USB port for programming and debugging and two rows of 20 pin headers to plug into a breadboard. The ESP32-PICO-D4 chip itself is small and requires only a few external components. Besides two core CPUs it integrates 4MB flash memory, a crystal oscillator and antenna matching components in one single 7 x 7 mm package. As a result the chip and all the components making the complete development board fit into 20 x 52 mm PCB.

The first release of ESP-WROVER-KIT shipped with ESP32-WROVER module installed by default. This release also introduced several design changes to conditioning and interlocking of signals to the bootstrapping pins. Also, a zero Ohm resistor (R166) has been added between WROVER/WROOM module and VDD33 net, which can be desoldered, or replaced with a shunt resistor, for current measurement. This is intended to facilitate power consumption analysis in various operation modes of ESP32. Refer to schematic - the changes are enclosed in green border.
