: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.

ESP32-PICO-KIT V4/V4.1 Getting Started Guide
|
||||
============================================
|
||||
|
||||
:link_to_translation:`zh_CN:[中文]`
|
||||
|
||||
This guide shows how to get started with the ESP32-PICO-KIT V4/V4.1 mini development board. For the description of other ESP32-PICO-KIT versions, please check :doc:`../../hw-reference/index`.
|
||||
|
||||
This particular description covers ESP32-PICO-KIT V4 and V4.1. The difference is the upgraded USB-UART bridge from CP2102 in V4 with up to 1 Mbps transfer rates to CP2102N in V4.1 with up to 3 Mbps transfer rates.

Overview
|
||||
--------
|
||||
|
||||
ESP32-PICO-KIT 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 with complete Wi-Fi and Bluetooth® functionalities. Compared to other ESP32 modules, ESP32-PICO-D4 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 links
|
||||
|
||||
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-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. For compatibility with Dupont wires, 2 x 17 header pads are populated with two rows of male pin headers. The remaining 2 x 3 header pads beside the antenna are not populated. These pads may be populated later by the user if required.
|
||||
|
||||
.. note::
|
||||
|
||||
1. There are two versions of ESP32-PICO-KIT boards, respectively with male headers and female headers. In this guide, the male header version is taken as an example.
|
||||
2. The 2 x 3 pads not populated with pin headers are connected to the flash memory embedded in the ESP32-PICO-D4 SiP module. For more details, see module's datasheet in `Related Documents`_.

概述
|
||||
----
|
||||
|
||||
ESP32-PICO-KIT 是一款来自 `乐鑫 <https://espressif.com>`_ 的迷你开发板。
|
||||
|
||||
该开发板的核心是具有完整 Wi-Fi 和蓝牙功能的 ESP32 系列 SiP 模组 ESP32-PICO-D4。与其他 ESP32 系列模组相比，ESP32-PICO-D4 模组已完整集成以下外围器件：
|
||||
|
||||
- 40 MHz 晶体振荡器
|
||||
- 4 MB flash
|
||||
- 滤波电容
|
||||
- 射频匹配网络等
|
||||
|
||||
这大大降低了用户额外采购和安装这些元器件的数量和成本，及额外组装测试的复杂度，并增加了可用性。
|
||||
|
||||
ESP32-PICO-KIT 集成了 USB 转 UART 桥接电路，允许开发人员直接通过 PC 的 USB 端口进行下载和调试。
|
||||
|
||||
为了便于连接，ESP32-PICO-D4 上的所有 IO 信号和系统电源管脚均通过开发板两侧焊盘（每侧 20 个 x 0.1 英寸间隔）引出。为了方便杜邦线的使用，ESP32-PICO-KIT 开发板每侧的 20 个焊盘中，有 17 个引出至排针，另外 3 个靠近天线的焊盘未引出，可供用户日后焊接使用。
|
||||
|
||||
.. note::
|
||||
|
||||
1. ESP32-PICO-D4 开发板目前有两种版本，分别采用排针与排母。本指南默认以排针版本为例。
|
||||
2. 每排未引出至排针的 3 个管脚已连接至 ESP32-PICO-D4 SiP 模组的内置 flash 模块。更多信息，请见 `相关文档`_ 中的模组技术规格书。
