*****************
:link_to_translation:`zh_CN:[中文]`
Overview
===========
ESP32-PICO-KIT-1 is an ESP32-based development board produced by `Espressif <https://espressif.com>`_.
The core of this board is `ESP32-PICO-V3 <https://www.espressif.com/en/products/socs>`_ - a System-in-Package (SiP) module with complete Wi-Fi and Bluetooth functionalities. Compared to other ESP32 modules, ESP32-PICO-V3 integrates the following peripheral components in one single package, which otherwise would need to be installed separately:
- 40 MHz crystal oscillator
- 4 MB flash
- Filter capacitors
- RF matching network
This setup reduces the costs of additional external components as well as the cost of assembly and testing and also increases the overall usability of the product.
The development board features a USB-to-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-V3 are led out to two rows of 18 x 0.1" header pads on both sides of the development board for easy access. For compatibility with Dupont wires, all header pads are populated with two rows of male pin headers.
.. note::
ESP32-PICO-KIT-1 comes with male headers by default.
ESP32-PICO-KIT-1 provides the users with hardware for development of applications based on the ESP32, making it easier for users to explore ESP32 functionalities.

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-V3 Standard ESP32-PICO-V3 module soldered to the ESP32-PICO-KIT-1 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-to-UART bridge CP2102N, single-chip USB-to-UART bridge that offers up to 3 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.
5V Power On LED This red LED turns on when power is supplied to the board. For details, see the schematic in `Related Documents`_.
I/O Connector All the pins on ESP32-PICO-V3 are broken out to pin headers. You can program ESP32 to enable multiple functions, such as PWM, ADC, DAC, I2C, I2S, SPI, etc. For details, please see Section `Pin Descriptions`_.
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.
================== =================================================================================================================================

.. note::
1. 该管脚已连接至板上 USB 桥接器芯片;
2. 32.768 kHz 晶振输入输出管脚:
- (a) 输入管脚;
- (b) 输出管脚;
3. ESP32-PICO-KIT-1 内置 SPI flash 的工作电压为 3.3 V。因此Strapping 管脚 MTDI 在上电复位过程中应拉低。如果连接了该管脚,请确保该管脚在复位中不要拉高。
