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 `_. 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. .. figure:: ../../../_static/esp32-pico-kit-v3-layout.jpg :align: center :alt: ESP32-PICO-KIT V3 board layout :figclass: align-center ESP32-PICO-KIT V3 board layout Below is the description of the items identified in the figure starting from the top left corner and going clockwise. ================== ================================================================================================================================= 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.
