Main Components & Basic Introduction
EN: Reset button
Boot: Download key. Press and hold the Boot key while pressing the EN key (do not release the Boot key at this time) to enter Firmware Download mode and download the firmware via the serial port.

USB-to-UART Bridge: A single chip USB-UART bridge that provides a transfer rate of up to 3 Mbps.

Micro USB Interface: USB interface that can be used as a power supply for the board or as a communication interface between the PC and the ESP32-WROOM-32 modules.

5V Power On LED: This indicator lights up when the board is powered on (USB or external 5 V).

I/O: Users can program the ESP32 to implement various functions such as PWM, ADC, DAC, I2C, I2S, SPI and so on.

Overview:
ESP32-DevKitC is a small development board based on ESP32. Most of the pins of the modules on the board have been pinned out, so developers can easily connect a variety of peripheral devices via jumper cables according to the actual needs, or plug the board into a breadboard for use.It has 4MB Flash, I/O, USB as well as buttons and LEDs.with a rich set of peripherals and an optimised pin layout to help users quickly realise their product development.

Supports Wi-Fi & Bluetooth Connectivity
ESP32-DevKitC is a small development board based on ESP32 modules, supporting Wi-Fi and Bluetooth functions. The board is equipped with a rich set of peripherals, which enables users to easily develop their products.

Easy and fast development
The ESP32-DevKitC has excellent RF performance, which allows users to design and develop applications without having to consider RF and antenna design. Basic system requirements are included on the board, so users can simply connect the USB cable and start development.

Flexible and Rich Features
The ESP32-DevKitC features complete circuitry to support the ESP32-WROOM, ESP32-WROVER and ESP32-SOLO family of modules, including key components such as the USB-UART bridge, Reset and Boot buttons, LDO regulators and Micro-USB connectors. Key GPIO ports are pinned out for developer use.

Easy Breadboard Insertion
The ESP32-DevKitC has an optimised pinout that makes it easy to plug it into a breadboard for development and debugging. On-board LDOs are pinned out to power external components, and the ESP32-DevKitC groups different peripheral interfaces to help users easily get started with product development.

Package included:
2* ESP32-DevKitC、ESP32-WROOM-32E Core Board、4*rows of pins

Note: Before powering up the ESP32-DevKitC, please make sure the development board is intact first.
