 ESP-IDF Programming Guide  » Get Started » ESP32-S2-DevKitC-1 ESP32-S2-DevKitC-1 [中⽂] This user guide will help you get started with ESP32-S2-DevKitC-1 and will also provide more in-depth information. ESP32-S2-DevKitC-1 is an entry-level development board based on ESP32-S2-SOLO (on-board PCB antenna) or ESP32-S2-SOLO-U (external antenna connector), which are two general-purpose modules with a 4 MB SPI flash. This board integrates complete Wi-Fi functions. 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-S2-DevKitC-1 on a breadboard. ESP32-S2-DevKitC-1 with the ESP32-S2-SOLO Module The document consists of the following major sections: Getting Started: Overview of ESP32-S2-DevKitC-1 and hardware/software setup instructions to get started. Hardware Reference: More detailed information about the ESP32-S2-DevKitC-1’s hardware. Hardware Revision Details: Revision history, known issues, and links to user guides for previous versions (if any) of ESP32-S2-DevKitC-1. Related Documents: Links to related documentation. Getting Started This section provides a brief introduction of ESP32-S2-DevKitC-1, instructions on how to do the initial hardware setup and how to flash firmware onto it. Description of Components ESP32-S2-DevKitC-1 - front The key components of the board are described in a clockwise direction. Key Component Description ESP32-S2-SOLO or ESP32-S2-SOLO-U ESP32-S2-SOLO and ESP32-S2-SOLO-U are two general-purpose Wi-Fi modules with a 4 MB SPI flash. ESP32-S2-SOLO comes with an on-board PCB antenna and ESP32-S2-SOLO-U comes with a connector for an external antenna. Both modules have two variants, depending on whether the chip embedded has a 2 MB PSRAM. 3.3 V Power On LED Turns on when the USB power is connected to the board. USB-to-UART Bridge Single USB-to-UART bridge chip provides transfer rates up to 3 Mbps. Pin Headers All available GPIO pins (except for the SPI bus for flash) are broken out to the pin headers on the board. For details, please see Header Block. ESP32-S2 USB Port ESP32-S2 full-speed USB OTG interface, compliant with the USB 1.1 specifications. The interface is used for power supply to the board, for flashing applications to the chip, and for communication with the chip using USB 1.1 protocols. Reset Button Press this button to restart the system. Key Component Description Boot Button Download button. Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port. USB-to-UART Port A Micro-USB port used for power supply to the board, for flashing applications to the chip, as well as the communication with the chip via the on-board USB-to-UART bridge. RGB LED Addressable RGB LED, driven by GPIO18. 5 V to 3.3 V LDO Power regulator that converts a 5 V supply into a 3.3 V output. Start Application Development Before powering up your ESP32-S2-DevKitC-1, please make sure that it is in good condition with no obvious signs of damage. Required Hardware ESP32-S2-DevKitC-1 USB 2.0 cable (Standard-A to Micro-B) Computer running Windows, Linux, or macOS  Note Be sure to use an appropriate USB cable. Some cables are for charging only and do not provide the needed data lines nor work for programming the boards. Hardware Setup Connect the board with the computer using USB-to-UART Port. Connection using ESP32-S2 USB Port is not fully implemented in software. In subsequent steps, USB-to-UART Port will be used by default. Software Setup Please proceed to ESP-IDF Get Started, where Section Installation Step by Step will quickly help you set up the development environment and then flash an application example into your ESP32-S2-DevKitC-1. Contents and Packaging Retail orders If you order a few samples, each ESP32-S2-DevKitC-1 comes in an individual package in either antistatic bag or any packaging depending on your retailer. For retail orders, please go to https://www.espressif.com/en/company/contact/buy-a-sample. Wholesale Orders If you order in bulk, the boards come in large cardboard boxes. For wholesale orders, please go to https://www.espressif.com/en/contact-us/sales-questions. Hardware Reference Block Diagram The block diagram below shows the components of ESP32-S2-DevKitC-1 and their interconnections. ESP32-S2-DevKitC-1 (click to enlarge) Power Supply Options There are three mutually exclusive ways to provide power to the board: USB-to-UART Port and ESP32-S2 USB Port (either one or both), default power supply (recommended) 5V and G (GND) pins 3V3 and G (GND) pins Header Block The two tables below provide the Name and Function of the pin headers on both sides of the board (J1 and J3). The pin header names are shown in ESP32-S2-DevKitC-1 - front. The numbering is the same as in the ESP32-S2-DevKitC-1 Schematic (PDF).
