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-SOLO and ESP32-S2-SOLO-U are two general-purpose Wi-Fi modules. ESP32-S2-SOLO comes with an on-board PCB antenna and ESP32-S2-SOLO-U comes with a connector for an external antenna. ESP32-S2-SOLO or ESP32-S2-SOLO-U on the board may come either with a 4 MB flash, or a 4 MB flash plus a 2 MB PSRAM embedded in the chip.
