Overview

ESP32-DevKitC V4 is a small-sized ESP32-based development board produced by Espres-sif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing. Developers can either connect peripherals with jumper wires or mount ESP32-DevKitC V4 on a breadboard.

To cover a wide range of user requirements, the following versions of ESP32-DevKitC V4 are available:

different ESP32 modules

ESP32-WROOM-32

ESP32-WROOM-32D

ESP32-WROOM-32U

ESP32-SOLO-1

ESP32-WROVE

ESP32-WROOM-32D/U ESP32-WROVER Type-C

Features

1.ESP32-DevKitC development board, the new version of the mainstream TYPE-C interface, the backplane can be equipped with ESP32 modules: ESP-WROOM-32,ESP-WROOM-32D,ESP-WROOM-32U, ESP32-WROVER.
2.ESP32-DevKitC is an entry-level ESP32 development board with integrated ESP32 pins pinned out for easy connection and use. It can be used to evaluate the full range of ESP32 modules and chips, and can be easily plugged into a breadboard.
3.ESP32-DevKitC is a small development board based on ESP32 modules, supporting Wi-Fi and Bluetooth functions. The board has a rich set of peripherals, so users can easily realize product development.
4.The on-board LDOs are led out to supply power for external components.ESP32-DevKitC groups different peripheral interfaces to help users get started with product development easily.
5. The ESP32-DevKitC has excellent RF performance, allowing users to design and develop applications without having to consider RF and antenna design. The basic system requirements are already included on the development board, so users only need to connect the USB cable for development.
