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 machine through sensory channels and body language.

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 Touch panel to control audio playback and adjust 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-WROVER Module: Module integrating the ESP32-S2 chip that provides Wi-Fi connectivity, data processing power, and flexible data storage.
4.3inch 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.
3.2inch LCD FPC connector: Connect a 3.2” LCD extension board (e.g., ESP-LyraP-LCD32) using the FPC cable.
