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.

* - 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/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.
