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
