The ESP32-S2-Kaluga-1 is a development kit mainly designed for human-computer interaction applications. It includes one main-board and four extension boards that support: touch panel control, audio playback, LCD display and camera image acquisition, which allows users to interact with machines through sensory channels and body language.

User Guide available here

Touch Panel Control

14 touch sensors, three of which support distance detection(proximity mode)
Support acrylic panels up to 5mm
Wet hand operation
Mis-touch prevention; 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.

Audio Playback

Connect speakers to play audio
Use together with the Touchpanel to control audio playback and adjust the volume

LCD Display

LCD interface(8-bit parallel RGB, 8080, and 6800 interface)
Support display with ST7789 and ILI9341 driver
Support camera data real-time display on LCD screen

Camera Image Acquisition

Support OV2640 and OV3660 camera modules
8/16-bits DVP image sensor interface
Clock frequency up to 40MHz
Optimized DMA transmission bandwidth for easier transmission of high-resolution images

Description of Components

ESP32-S2-Kaluga-1 Development Board Features

Key Component	Description
ESP32-S2-WROVER Module	Module integrating the ESP32-S2 chip that provides Wi-Fi connectivity, data processing power, and flexible data storage.
4.3” LCD FPC Connector	(Reserved) Connect to a 4.3” LCD extension board using the FPC cable.
ESP Prog Connector	(Reserved) Connection for Espressif’s download device (ESP-Prog) to flash ESP32-S2 system.
JTAG Switch	Switch to ON to enable connection between ESP32-S2 and FT2232; JTAG debugging will then be possible using USB-UART/JTAG Port. See also JTAG .
Breakout Header 2	Some GPIO pins of the ESP32-S2-WROVER module are broken out to this header, see labels on the board.
USB-to-UART/JTAG Bridge	FT2232 adapter board allowing for communication over USB port using UART/JTAG protocols.
Camera Header	Mount a camera extension board here (e.g., ESP-LyraP-CAM).
Extension Header	Mount the extension boards having such connectors here.
Reset Button	Press this button to restart the system
Boot Button	Holding down Boot and then pressing Reset initiates Firmware Download mode for downloading firmware through the serial port.
USB-UART/JTAG Port	Communication interface (UART or JTAG) between a PC and the ESP32-S2 module.
USB Power Port	Power supply for the board.
Battery Port	Connect an external battery to the 2-pin battery connector.
Power On LED	Turns on when the USB or an external power supply is connected to the board.
Power Switch	Switch to ON to power the system.
RGB Jumper	To have access to the RGB LED, place a jumper onto the pins.
RGB LED	Programmable RGB LED and controlled by GPIO45. Before using it, you need to put RGB Jumper ON.
Power Regulator	Regulator converts 5 V to 3.3 V.
I2C FPC Connector	(Reserved) Connect to other I2C extension boards using the FPC cable.
Breakout Header 1	Some GPIO pins of the ESP32-S2-WROVER module are broken out to this header, see labels on the board.
Touch FPC Connector	Connect the ESP-LyraP-TouchA extension board using the FPC cable.
Touch Switch	In OFF position, GPIO1 to GPIO14 are used for connection to touch sensors; switch to ON if you want to use them for other purposes.
3.2” LCD FPC connector	Connect a 3.2” LCD extension board (e.g., ESP-LyraP-LCD32) using the FPC cable.
