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.

Getting Started
|
||||||
|
================
|
||||||
|
|
||||||
|
This section describes how to get started with the ESP32-PICO-KIT-1. It begins with a few introductory sections about the ESP32-PICO-KIT-1, then Section `Start Application Development`_ provides instructions on how to flash firmware onto the ESP32-PICO-KIT-1.

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.

Power Supply Options
|
||||||
|
--------------------
|
||||||
|
|
||||||
|
There are three mutually exclusive ways to provide power to the board:
|
||||||
|
|
||||||
|
* Micro USB port, default power supply
|
||||||
|
* 5V/GND header pins
|
||||||
|
* 3V3/GND header pins
|
||||||
|
|
||||||
|
.. warning::
|
||||||
|
|
||||||
|
The power supply must be provided using **one and only one of the options above**, otherwise the board and/or the power supply source can be damaged.
|
||||||
|
|
||||||

|
|
||||||
|
1. This pin is connected to the pin of the USB bridge chip on the board.
|
||||||
|
2. 32.768 kHz crystal oscillator:
|
||||||
|
a) input
|
||||||
|
b) output
|
||||||
|
3. The operating voltage of ESP32-PICO-KIT-1’s embedded SPI flash is 3.3 V. Therefore, the strapping pin MTDI should be pulled down during the module power-on reset. If connected, please make sure that this pin is not held up on reset.

概述
|
||||||
|
======
|
||||||
|
|
||||||
|
ESP32-PICO-KIT-1 是一款基于 `ESP32 <https://www.espressif.com/zh-hans/products/socs/esp32>`_ 的乐鑫开发板，板上搭载 `ESP32-PICO-V3 <https://www.espressif.com/zh-hans/products/socs>`_ （SiP，系统级封装）模组。ESP32-PICO-V3 具备完整的 Wi-Fi 和蓝牙功能，与其它 ESP32 系列模组相比，此模组已集成下述外围组件，无需额外安装：
|
||||||
|
|
||||||
|
- 40 MHz 晶振
|
||||||
|
- 4 MB flash
|
||||||
|
- 滤波电容
|
||||||
|
- 射频匹配网络等
|
||||||
|
|
||||||
|
将上述组件封装至 ESP32-PICO-V3，用户无需额外购买，大大降低了安装和测试的成本，同时也增加了产品的可用性。
|
||||||
|
|
||||||
|
ESP32-PICO-KIT-1 开发板还集成了 USB-to-UART 桥接电路，方便开发人员直接通过 PC 的 USB 端口直接进行固件烧录和调试。
|
||||||
|
|
||||||
|
为方便硬件连接，ESP32-PICO-V3 上的所有 IO 信号和系统电源管脚均引出至开发板两侧焊盘 (18 x 0.1")。上述 18 个焊盘也均引出至排针，可使用杜邦线连接。
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
|
||||||
|
ESP32-PICO-KIT-1 开发板默认采用排针。
|
||||||
|
|
||||||
|
ESP32-PICO-KIT-1 为用户提供了基于 ESP32 芯片应用开发的硬件，更加方便用户探索 ESP32 芯片的功能。
