Getting Started
===============
This section describes how to get started with the ESP32-S2-Kaluga-1. It begins with a few introductory sections about the ESP32-S2-Kaluga-1, then Section `Start Application Development`_ provides instructions on how to do the initial hardware setup and then how to flash firmware onto the ESP32-S2-Kaluga-1.
Overview
--------
The ESP32-S2-Kaluga-1 main board is the heart of the kit. It integrates the ESP32-S2-WROVER module and all the connectors for extension boards. This board is the key tool in prototyping human-computer interaction interfaces.
The ESP32-S2-Kaluga-1 board has connectors for:
- Boards with the Extension Header (ESP-LyraT-8311A, ESP-LyraP-LCD32)
All the four extension boards are specially desgined to support the following features:
* Touch panel control
* 14 touch sensors, three of which support distance sensing (proximity mode)
* Supports acrylic panels up to 5 mm
* Wet hand operation
* Water rejection, ESP32-S2 can be configured to disable all touchpads automatically if multiple pads are simultaneously covered with water and to re-enable touchpads if the water is removed
Please proceed to :doc:`../../get-started/index`, where Section :ref:`get-started-step-by-step` will quickly help you set up the development environment.
