This user guide provides information on Espressif's small-sized development board ESP32-S2-DevKitM-1(U).
This user guide provides information on Espressif's small-sized development board ESP32-S2-DevKitM-1.
ESP32-S2-DevKitM-1(U) is a general-purpose development board based on `ESP32-S2FH4 <https://www.espressif.com/sites/default/files/documentation/esp32-s2_datasheet_en.pdf>`__ chip, which falls into ESP32-S2 chip series. With a rich peripheral set and optimized pinout, this board allows rapid prototyping.
ESP32-S2-DevKitM-1 is embedded with `ESP32-S2-MINI-1 <https://www.espressif.com/sites/default/files/documentation/esp32-s2-mini-1_esp32-s2-mini-1u_datasheet_en.pdf>`__ module (on-board PCB antenna), while ESP32-S2-DevKitM-1U with `ESP32-S2-MINI-1U <https://www.espressif.com/sites/default/files/documentation/esp32-s2-mini-1_esp32-s2-mini-1u_datasheet_en.pdf>`__ module (external antenna connector).
ESP32-S2-DevKitM-1 is entry-level development board. Most of the I/O pins on the module 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-DevKitM-1 on a breadboard.

Getting Started
===============
This section describes how to get started with ESP32-S2-DevKitM-1(U). It begins with a few introductory sections about the ESP32-S2-DevKitM-1(U), then Section `Start Application Development`_ provides instructions on how to get the ESP32-S2-DevKitM-1(U) ready and flash firmware into it.
Overview
--------
ESP32-S2-DevKitM-1(U) is entry-level development board equipped with either ESP32-S2-MINI-1 or ESP32-S2-MINI-1U module. Most of the I/O pins on the module 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-DevKitM-1(U) on a breadboard.
