The description of components starts from the ESP32-S2 module on the left side and
Description
Module integrating the ESP32-S2 chip that provides Wi-Fi connectivity, data
processing power, and flexible data storage.
(Reserved) Connect to a 4.3"LCD extension board using the FPC cable.
(Reserved) Connection for Espressif's download device (ESP-Prog) to flash
ESP32-S2 system.
Switch to ON to enable connection between ESP32-S2 and FT2232; JTAG
debugging will then be possible using USB-UART/JTAG Port. See also
Debugging.
Some GPIO pins of the ESP32-S2-WROVER module are broken out to this
header, see labels on the board.
FT2232 adapter board allowing for communication over USB port using
UART/JTAG protocols.
Mount a camera extension board here (e.g., ESP-LyraP-CAM).
Mount the extension boards having such connectors here.
Press this button to restart the system
Holding down Boot and then pressing Reset initiates Firmware Download
mode for downloading firmware through the serial port.
Communication interface (UART or JTAG) between a PC and the ESP32-S2
module.
Power supply for the board.
Connect an external battery to the 2-pin battery connector.
Turns on when the USB or an external power supply is connected to the board.
Switch to ON to power the system.
To have access to the RGB LED, place a jumper onto the pins.
Programmable RGB LED and controlled by GPIO45. Before using it, you
need to put RGB Jumper ON.
Regulator converts 5 V to 3.3 V.
(Reserved) Connect to other I2C extension boards using the FPC cable.
Some GPIO pins of the ESP32-S2-WROVER module are broken out to this
header, see labels on the board.
Connect the ESP-LyraP-TouchA extension board using the FPC cable.
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.
Connect a 3.2" LCD extension board (e.g., ESP-LyraP-LCD32) using the FPC
cable.
Before powering up your ESP32-S2-Kaluga-1, please make sure that it is in good
